DroneMobile Smartphone Vehicle Control Response Time vs OEM

Smartphone Control

Being able to lock, unlock or remote start your car or truck using an app on your smartphone is handy. In listening to what owners of these solutions have been saying over the last few years, we’ve noticed a disturbing pattern: Most factory-installed remote systems are agonizingly slow. Nobody wants to wait around for their vehicle to unlock. So let’s do some research and see how the DroneMobile system from Firstech stacks up in terms of responsiveness.

What Is a Telematics System?

In the context of cars and trucks, telematics is a way of remotely controlling basic vehicle functions using an app on your smartphone. In essence, these systems replicate the operation of a key fob to let you lock or unlock your vehicle, pop the trunk or hatch, or remote start the engine. In addition, many systems include a GPS receiver that can locate your vehicle on a map or configure location-based security alerts.

DroneMobile is the aftermarket telematics system offered by Firstech – the company behind Compustar remote car starter and security systems. DroneMobile can be integrated with a Compustar remote car starter to provide unlimited control range. So long as your vehicle is parked somewhere with cellular service and your smartphone has access to the internet, you can send commands quickly and easily.

DroneMobile does much more than just let you lock, unlock and remotely start your vehicle.

Smartphone Control Response Time

In addition to reliability and ease of use, impressive response time is one of the main reasons thousands of people have upgraded their cars and trucks with this system. Firstech moved its authentication services to AWS a few years ago to increase reliability and responsiveness. AWS is one of the world’s premier cloud computing platforms and is used by companies like Netflix, Amazon, Capital One, Coca-Cola, Expedia and thousands more to host their online platforms.

If you’re sitting at your desk at work and want to remote start your vehicle with your smartphone, it doesn’t matter significantly if the process takes 2, 20 or 120 seconds. However, if you’re walking up to your vehicle and want to use your phone to unlock it, response time matters. The last thing you want is to stand in front of your vehicle for 30, 40 or 60 seconds while data commands travel around the globe. You want the system to unlock as quickly as possible so you can be on your way.

We surveyed a group of friends to look at the response time of the telematics systems that came with their cars and trucks. The answers were surprising in all regards. Most response times were slower than we expected, with a surprisingly significant number of users completely giving up on these systems because they often didn’t respond.

Smartphone Control

If we average all the responses, it took just under 18 seconds from when an icon on the smartphone was pressed to when the vehicle responded on most factory-installed telematics systems. In most cases, this was a simple lock or unlock command. However, the time it took for these vehicles to remote start and then report their status back to the app was often more than twice that.

DroneMobile – The King of Vehicle Remote Control Speed

Most of the employees at BestCarAudio.com have Compustar remote starters installed in their vehicles. We also have DroneMobile telematics systems integrated with those starters. We surveyed our team and many of our peers and found that the average response time for a lock or unlock request was about 2 seconds. In some cases, it was less. Sending a lock command over LTE was often faster than using a one-button RF remote. This isn’t a failing of the remote – it waits a second before transmitting to see if you’re going to press the button again.

If you have remote started your car or truck from inside your home, work, a restaurant or movie theater and are approaching the vehicle, using the DroneMobile system to unlock the doors in about 2 seconds is, frankly, the way these systems should work.

Upgrade Your Vehicle with DroneMobile

Many friends we talked with for this article expressed an interest in replacing the factory system with a solution like DroneMobile. The slow response time or complete failure of the system to function had led many of them to abandon using the factory-installed solutions. If you’re shopping for a lightning-quick telematics system for your car or truck, drop by a local DroneMobile retailer today. You can learn more about this impressive smartphone control solution by visiting the DroneMobile website, their Facebook page, Instagram feed or YouTube channel.

Convenience System Accessories

Convenience System Accessories

A remote starter, keyless entry or security system is a great way to enhance the functionality of your vehicle. A remote starter can make dealing with weather extremes much more comfortable. A properly installed security system can let you know if someone damages your vehicle or tries to steal it. If your car didn’t come with a remote control to unlock the doors, a keyless entry system can speed up the process of getting into your vehicle and locking it when you leave. An entire list of convenience options can be added to these systems to make them even more convenient and further improve the security of your vehicle.

Cellular Interface

ConvenienceMany companies sell smartphone interfaces for remote start and security systems. These systems work by interfacing between an app on your smartphone and the convenience system in your vehicle. Yes, you have to pay for a monthly (or yearly) service plan, so don’t be surprised by that aspect. These systems will allow you to lock and unlock your vehicle, start it remotely (if you have a remote starter installed), and pop the trunk if that is hooked up.

The best part is that if you have a security system, your phone will alert you with a message if your alarm goes off. Anywhere your car and your smartphone have access to a cellular connection, you can control the system.

Many smartphone interfaces include GPS receivers. Such a receiver can send the longitude and latitude of your vehicle to the app on your smartphone. This information will let you know exactly where your vehicle is and how fast it is traveling. The app also can let you know right away if the vehicle moves when it’s not supposed to.

Some of these systems include the ability to monitor battery voltage, advise you of vehicle diagnostic codes and tell you the temperature of the vehicle interior. A few of these systems include a built-in backup battery and will alert you if the unit is disconnected.

Power Window Control Interfaces

One of the “classic” convenience accessories is the power window interface. This module lets your convenience system roll your windows up and down with the press of a button on your remote. The system can be programmed to roll the windows up when the doors are locked. Many of these window control systems have the option of venting a window an inch or two with a short press of the button on your remote, then rolling the window down completely when you hold the button for a second or two.

Power window modules also can be used to control sliding doors or sun roofs.

Tilt and Motion Sensors

ConvenienceIf you are worried about someone stealing your wheels or towing your vehicle, then a tilt and motion sensor would be a great addition. These sensors calibrate themselves each time the alarm is armed, then trigger the system when the vehicle angle changes by more than a couple degrees. These sensors should not trigger the alarm under normal wind conditions, thanks to integrated software that recognizes when the vehicle is rocking.

Backup Battery Siren

If you are concerned about someone cutting you the wire to your siren so they can work on bypassing the rest of a security system, ask your mobile electronics retailer about a battery backup siren. These sirens will go off if someone cuts the wiring to it. A key on the siren will turn it off.

Radar Sensors Boost Protection

If you have a convertible-top vehicle or like to leave your windows down, a radar or field disturbance sensor is a great way to keep your vehicle protected. These sensors Convenienceusually have two stages of protection. The first will provide a warning to an intruder when something or someone enters the field. The second triggers the alarm right away. Your installer can fine-tune the size of the fields for a given sensor mounting location and vehicle type.

Keypads Add Convenience

Several companies offer convenience keypads that attach to the inside of your windshield. You can type in a code of your choice to arm or Conveniencedisarm the system.

Some keypads have the option of acting as a pager for an owner who has a two-way remote or smartphone interface. These systems use technology similar to what a smartphone uses with a glass screen uses to detect your finger presses.

Proximity Remote

Many new cars have proximity keys that unlock the doors when you walk up to the vehicle. Your installer can add similar technology to an aftermarket keyless entry system. You simply keep a fob in your pocket. When you walk up to the vehicle, it will disarm the alarm without your having to press a button.

High-output Sirens

ConvenienceIf you want to get people’s attention when your alarm goes off, then the addition of a high-output siren is just for you. Some of these sirens are extremely loud, while others offer a sound that is truly ear-piercing! These high-frequency sirens are often called pain generators and are typically installed in the vehicle.

Protecting your vehicle from theft or vandalism is an art. Some installers take great pride in their security system installations. They conceal wiring in the dash very carefully and use wire protection that matches the factory look and feel. Split-loom, flexible-conduit, Tesa tape and vinyl tape are just some of the wire protection options. Installers route wires with factory wiring to further conceal their work.

Adding features and functionality to a security or convenience system is a great way to enhance its performance and usefulness. These are just a few of the possible additions available. Be sure to ask your local mobile electronics specialist retailer about the options they have available.

Product Spotlight: Rockford Fosgate HD14RGST-STAGE3 Harley-Davidson Stereo Upgrade

Rockford Fosgate HD14RGST-STAGE3

Rockford Fosgate has cemented itself as the undisputed leader in Harley-Davidson motorcycle audio system upgrades in the past few years. They offer dozens of direct bolt-in speaker and amplifier kits for all the popular touring bike models. In this spotlight, we will look at the HD14RGST-STAGE3 aftermarket audio system for 2014 and newer Street Glide and 2015 and up Road Glide touring bikes. This kit also works with the Road Glide Special and Street Glide Special bikes from the same year.

Rockford Fosgate HD14RGST-STAGE3

Harley-Davidson has done a good job engineering the Boom! Box infotainment system on the latest touring bikes. Although the source unit is amazing, the first-generation factory-installed sound system falls short in speaker output capability and power delivery. Rockford Fosgate’s HD14RGST-STAGE3 kit is the perfect upgrade to make the audio system crystal clear at 75 mph and even drown out that rowdy exhaust note.

The HD14RGST-STAGE3 includes a set of Power Series 6.5-inch speakers and grilles for the front fairing, a pair of 6×9-inch speakers and grilles for the saddlebags, a Power Series four-channel amplifier and all the wiring, connectors and mounting components your installer will need to complete the installation. Best of all, everything integrates into the wiring on the bike without any modifications so it won’t affect a brand-new motorcycle’s electrical system warranty.

The TMS65 and TMS69 speakers in the kit were designed specifically for motorcycle and powersports applications – meaning they are frequency-response tuned for open-air environments and protected to withstand the harsh outdoors. They include oversized voice coils on the woofers to handle extreme power levels for long periods. The Vertical Attach Surround Technique (VAST) cone and surround design increases the effective radiating area of these drivers to deliver more output than conventional drivers. Grilles are included for both the Road Glide and Street Glide fairings.

The HD14RGST-STAGE3 system includes the TMS69BL14 saddlebag speaker installation kit. Your installer can mount the TMS69 speakers in the bag lid covers quickly and efficiently with these parts. There’s no need to spend money or waste time color-matching new lid covers to get great sound. Finally, these speakers are designed to meet Rockford Fosgate’s strict Element Ready requirements to withstand rain, dust and prolonged UV exposure without failing.

The TMS69BL14 Saddlebag Speaker Kit is a perfect solution to add big sound to your existing saddlebags.

The TM400X4ad four-channel amplifier is rated to simultaneously produce up to 100 watts of power to each of the four speakers. Knowing how Rockford Fosgate rates its amps, actual power is likely 10 to 15% higher. The system includes the RFK-HD14 amplifier mounting bracket with an integrated heatsink that works with Bat Wing and Shark Nose fairings. Power wiring, speaker connectors and signal input harness with OE-grade Harley-specific connectors are also included. The optional DSR1 digital signal processor can easily be added to upgrade the system using the included loop-through harness.

Speaking of the factory-installed Boom! Box radio, an authorized Rockford Fosgate retailer will need to flash the software in the radio to change its built-in equalizer settings before bringing the new amp and speakers to life. You can find a retailer with the tools and training to do this here.

Product Spotlight: Rockford Fosgate P1650 and P1694

Rockford Fosgate Speakers

Would you think it was possible to pack a whole slew of technologies into a pair of car audio speakers? For the fanatics at Rockford Fosgate, that tech translates to more output and better sound in your vehicle. In this product spotlight, we’ll take a deep dive into the Punch Series P1650 6.5-inch and the P1694 6×9-inch sets.

Rockford Fosgate P1650 Speakers

Rockford Fosgate Speakers

Perhaps the most popular speaker size today is the 6.5-inch coaxial. This size fits into hundreds of models of cars and trucks. The Punch Series P1650 set includes a pair of coaxial speakers that feature mineral-filled, injection-molded polypropylene woofer cones and ¾-inch treated PEI dome tweeters. The addition of minerals like mica helps damp resonances to reduce distortion while improving the thermal stability of the cones.

The cone is attached to the basket with a Santoprene rubber surround that will outlast conventional foam designs. The P1650 drivers use the Vertical Attach Surround Method (VAST) to increase the effective radiating area of the driver for more efficiency and bass output. To ensure smooth frequency response, the P1650 set uses -12 dB/octave crossovers concealed within the basket. Rockford Fosgate calls this its Integrated Concealed Crossover (ICC) design. In addition to being neat and tidy, there are no extra modules (external crossover enclosures) for your installer to deal with, so the installation will be quick and efficient.

Choosing speakers that fit your vehicle is as important as selecting ones that sound great. The P1650 speakers feature the FlexFit2 stamped basket design. This design provides eight mounting holes and eight elongated slots to ensure that the speaker can fit a variety of vehicle OEM mounting points. The mounting depth is specified at 2.24 inches. A set of steel mesh grilles is also included.

Wrapping up the specs on these drivers, we have a continuous power handling rating of 55 watts and a max rating of 110 watts. Their nominal impedance is 4 ohms, and they have a sensitivity rating of 88 dB SPL at 1 watt at 1 meter. Sensitivity at this level typically indicates that the suspension design is optimized for sound quality.

If you have a car or truck with 6×9 speaker locations in the doors or rear parcel shelf and you want to rock out, the four-way P1694 6×9 set is the perfect option. Once again, these speakers include the same mineral-doped polypropylene woofer material as their little brothers and use the VAST surround design for optimized efficiency. These drivers feature a pair of PEI dome tweeters that flank a compact titanium composite cone midrange driver that also includes a rubber surround.

The mounting depth on the P1694 speakers is 3.07 inches, and the drivers include steel mesh grilles and mounting hardware. They can handle 75 watts of power continuously and peaks of 150 watts. Their nominal impedance is 4 ohms, and they have an impressive 91 dB SPL 1W/1M efficiency rating.

It’s worth noting that all of Rockford Fosgate’s speaker and subwoofer specifications fully comply with the CTA-2031 standard for the Testing and Measurement of Mobile Loudspeaker Systems. What does this mean? The dimensions are accurate, and the specifications are entirely believable and uninflated. Not all car audio brands can make this statement.

Are Single or Dual Voice Coil Subwoofers Better?

Voice CoilWhen it comes to buying subwoofers, a lot of people have questions or make assumptions about the benefits and drawbacks of single voice coil and dual voice coil versions. Understanding the differences between them requires a slightly enhanced understanding of how an amplifier works. We cover both topics in this article.

How an Amplifier Works

An amplifier is a simple device that takes an audio signal (from your radio, for example) and increases the voltage. That’s it.

You may (logically) be asking yourself, “Why do we call it a power amplifier?” We get an increase in power because the speakers we connect to the outputs of the amplifier have a low impedance. In car audio, we typically see loads between 1 and 4 ohms. This low impedance, combined with the increased voltage of the audio signal in the amplifier, causes relatively large amounts of current to flow through the voice coil of the speaker. This current flow causes a magnetic field and, subsequently, the voice coil moves toward or away from the magnetic field created by the stationary magnet on the speaker.

(OK, maybe this didn’t stay as simple as originally planned.)

Amplifier Load Determines Amplifier Power

Voice Coil
Ohm’s Law Pie Chart
Let’s use an example of an amplifier that has a peak output voltage of 20 V. We don’t need to worry about the fact that this is an alternating current signal – we will examine this at a single point in time. With 20 V applied to our voice coil, let’s say we have a 4 ohm impedance on this coil. Ohm’s law states that a potential of 20 volts applied across a resistance of 4 ohms will result in 5 amp of current to flow. Using the equation P (Power) = Voltage x Current, we get 20 x 5, or 100 watts of power. If we change the impedance of the load to 2 ohms, we double the current to 10 amps, for a resulting power level of 200 watts.

If you look at the specifications for an amplifier, especially a subwoofer amplifier, you will see power ratings at different load impedances. In most cases, unless the voltage of the power supply in the amplifier is adjustable, amplifiers will make more power as the load impedance decreases.

What About These Subs?

Deciding which subwoofers to buy depends on the amp you are using and the number of subwoofers you are going to use. You want to choose a combination of subwoofers that will let you wire the voice coils together to an impedance that will allow the amp to make the power you want. Let’s look at several examples.

Example 1

Voice Coil

We have the option of two different fictional subwoofers, each rated for 750 watts of continuous power handling. One subwoofer has a single 4 ohm voice coil. The other subwoofer has dual 4 ohm voice coils.

The dual voice coil subwoofer can have its coils wired in series to produce an 8 ohm load, or in parallel to produce a 2 ohm load. To complete this fictional example, we have an amplifier that will produce 400 watts into a 4 ohm load and 700 watts into a 2 ohm load. We have a small car and want to use a single 12 inch subwoofer in a large vented enclosure to get maximum low-frequency output. What sub should we use?

If we use the single voice coil subwoofer, the amplifier will not make full power in the 4 ohm load. We should use the dual voice coil subwoofer and wire the voice coils in parallel to present the amp with a 2 ohm load.

Example 2

Voice Coil

In this example, we have the same electronic equipment, but the vehicle is a large SUV. There is a lot of room for subwoofers, and the owner wants to list to reggae, loudly. The owner has listened to a friend’s system and found out that a pair of subs matches his listening preferences perfectly. Which subs should we use?

If we use the dual voice coil subs, we have three options for wiring the four (two on each sub) voice coils together. We could wire all the coils in parallel. Parallel wiring will present the amp with a 1 ohm load. Most likely, the amp will go into protection because the load is too low. We could wire all the coils in series to present the amp with a 16 ohm load – but that’s not going to happen. We could wire the voice coils on each subwoofer in series, then parallel the pair of subwoofers to get a 4 ohm load. A 4 ohm load is not ideal.

If we use a pair of single voice coil subwoofers, however, and wire the subs in parallel, we get a 2 ohm load. Happy amp and happy customer!

Choosing and Wiring Subwoofers

  • Voice CoilYou can use as many subwoofers as you want on a single amplifier.
  • You must use all the voice coils on each sub. If you need a 4 ohm load but have a dual 4 ohm sub, using only one coil is going to cause issues. Bad issues.
  • Wire all the subwoofers you choose so the current going through each subwoofer is the same. In most cases, this means using pairs of subs. In the past, several companies offered dual 6 ohm voice coil subs that could be wired in groups of three to present amplifiers with standard load impedances of 1 or 4 ohms.

Do not wire one dual voice coil subs in series and one in parallel before connecting the subs together in parallel. You will get more current through the (parallel) low-impedance subwoofer. This imbalance will upset the performance of the enclosure and wreak havoc with the reliability and quality of your system. This is unrelated to the wiring of multiple subwoofers, but: Don’t mix and match different subwoofers. Each has its enclosure requirements and response characteristics. There is no way to guarantee that the output of two different subwoofers will sum positively at all frequencies.

So, Which Voice Coil Configuration Is Better?

The answer to the question “which is better” is neither. SVC and DVC subwoofers are simply two different options when buying. They are analogous to a tire manufacturer offering different-sized tires for different vehicles – there is an application for each.

Adding a subwoofer system should be one of the very first things you do to upgrade a factory audio system. When you are ready to make the leap into the realism, impact and dynamics that a great subwoofer can add, drop by your local car audio specialist retailer. They would be happy to work with you to design a system that meets your performance expectations.
