The Match PP52DSP signal processor will greatly improve the sound quality of your factory audio system without cutting a single wire or changing your vehicle's look. After the PP52DSP works its magic, you'll be able to hear music like you were in a recording studio, instead of a noisy vehicle on the road.
First, you'll need to purchase a vehicle-specific adapter harness that plugs in between your car's stock radio and speakers, then connects to the PP52DSP. The PP52DSP then takes the signal from the factory radio and transforms it into focused, clear, and powerfully moving music that'll veritably dance across your dashboard.
The processor's built-in amplifier puts out 35 watts RMS to each of your car's four speakers and sends another 160 watts RMS to an optional Match subwoofer, so you'll definitely feel big improvement in your music's impact. For you subwoofer fans who want more bass than that, the PP52DSP also includes outputs for hooking up your own larger amplifier and sub.
The main control panel for the PP52DSP, as it appears on your computer screen
If you're a constant tweaker who's crazy about sound quality, then you will have a blast with the PP52DSP. It works with your Windows-operated personal computer to offer a world of sonic adjustments that can maximize the performance of almost any car audio system.
Once you've downloaded the application and software from Helix, you plug your PC or laptop into the processor's USB port. A detailed control panel will appear on your computer screen that lets you set virtually every tunable audio parameter, so you can enjoy the highest musical fidelity possible in your car. The visual display shows the resulting sound curve of each setting, so you'll know for sure how your adjustments are affecting audio output.
The PP52DSP includes a 30-band graphic equalizer on every channel, to compensate for all the dips and bumps in your speakers' responses inside your car, so each speaker will sound its best. The EQ section also features a fine tuning adjustment that lets you get in between the preset bands to smooth out any rough spots. The time alignment feature lets you correct for each speaker's placement, so the sound from each speaker gets to you at the same time, centering the stereo image for your sitting position.
You can configure almost any type of high-pass and low-pass filter on each channel. Not only can you adjust a crossover's frequency, but you can also choose the slope, its "filter characteristics" (see Highlights below), and adjust its "Q-factor," which widens or tightens the bump at a particular crossover point. Filters and EQ can be set separately for each channel, or channels can be linked together for common settings.
Don't worry, you won't have to drive around with your computer plugged in. You simply download your settings to the PP52DSP, after saving them on your laptop. The PP52DSP can store two settings at once, so you can toggle between them to see which sounds better. You can also use an optional microSD memory card to store and transfer settings to your PP52DSP, which comes in handy when you want to switch settings without plugging in your laptop.
An auxiliary input lets you plug in other sources like an MP3 player or a navigation device. The PP52DSP senses when a signal is present there and automatically switches to AUX mode to play it. If it hears nothing for 2 seconds, it switches back to the receiver's signal.
You can use the URC-2A remote control (not included) to control several functions of your processor from the front seat, without having to plug in a computer. You can adjust the main and subwoofer volumes, switch between your receiver and auxiliary sources, and even quickly switch back and forth between two previously saved processor setups. You can re-configure some of the URC-2A's functions using the DSP-PC Software.
Many newer vehicles feature accessory circuits that remain on for several minutes after the engine shuts off, so an aftermarket amplifier could possibly drain your vehicle's battery. The Match PP52DSP solves this problem by turning off the amps connected to its remote output after not sensing music for 60 seconds. It will turn them back on within a second after sensing the signal.
For more details and tips, check out Audiotec Fischer's DSP Special Sound Tuning Magazine, which includes the operation and adjustment manual for the Match PP52DSP.
Important Note: This Match upgrade system plugs in between your vehicle's factory radio and speakers, so it will not work in a premium sound system equipped with a factory amplifier. You must identify your vehicle to order a Helix Match Plug and Play upgrade system online. Or, if you prefer, call an Advisor at 1-888-955-6000 to make sure you get the upgrade system that works in your vehicle.

This transformed the mediocre system in my 2013 Tiguan into something I can really enjoy. I'm hearing all kinds of details in music that I've never heard before. Hooking it up is super easy with the additional adapter and I'm able to use the head-unit power since I'm not driving a sub. The provided harness gave me plenty of room to locate the unit in the same spot a factory amp would be under the driver's seat. I had good luck setting the levels using pink noise from the Sheffield/Autosound 2000 Test CD and the built-in mic on a Macbook Pro. I bought a USB condenser mic which pics up the lower frequencies better but otherwise didn't make that much difference. I wasn't able to use the pre-built profile I downloaded from Audiotec-Fischer. A note about warranty coverage: I was worried about this given the price - didn't want to have to ship back to Germany! - so I tracked down these answers. I had little luck with the manufacturer Audiotec-Fischer. I finally got an answer from Rockford Fosgate. I was able to get this confirmed by Crutchfield. Rockford is the US distributor, so if warranty service is needed you can either return it to the dealer or contact Rockford Fosgate's customer service. Warning: If you're going to spend as much time as I did figuring out how to set the levels and finding the perfect sound, don't forget to hook up a battery charger!
Pros: Sound quality, correction of major sound issues - OEM system was so shrill it was distorting at high volumes, super easy plug and play with the adapter
Cons: Price, warranty coverage not clear, fixed input/output mapping for 4 factory channels - each input channel is mapped to the same output channel. You can only change the mapping for line out and sub outputs.
I am happy to report that this product does what it says. I elected to do the entire upgrade with this DSP and the PP7E subwoofer system. It was very easy to install, the hardest part was routing the wiring as the rest was plug n play. It has breathed fresh life into my OEM system of my 06 GTI. It cleaned up the signal, puts out clarity, adds depth and a nice low end to the sound. I am hearing parts of songs and instruments that were buried in the reproduction from my stock system. It's capabilities to customize the sound and imaging are limitless as I tune the system even more as I learn the dos and dont's. The customer support from Helix is incredible as there was no car specific profiles for my car at the time I purchased these products since this product was so new. After a couple of calls, I spoke to Rico who created the needed profile and got it to me ASAP. Of course, the folks at Crutchfield have been incredible as well although they did sell me a cable that was not needed but they will be taking it backing and paying shipping. There are 3 draw backs as I see it and that is why it didn't get a full 5 star rating. The price is high compared to the previous model as it has almost doubled. 2nd is the subwoofer options. They only offer the dual 7" system (Performs better than expected) even though they offer a wide selection in Germany. Last is the programming and instructions are a bit vague and I think that is due to German to English translation.
Pros: Easy to install, will revive your OEM system and make you want to love it again.
Cons: High price, Subwoofer options, Programming is a bit difficult and the instructions lack a little.
Overview: The Helix PP 52DSP is an amplifier and digital signal processor, designed to be used with a Helix vehicle specific adapter to create a plug & play upgrade to a factory stereo system. Once the PP 52DSP is installed, the vehicle specific profile containing customized EQ and time alignment data is downloaded from the Helix web site to a MicroSD card and loaded into the DSP (be sure to check their site before purchasing to confirm they have a profile for your car). This allows you to upgrade your vehicle's factory sound, while leaving all the factory features and controls intact. If no profile is available for your vehicle, extensive adjustments can be made to the EQ, crossover, and time alignment using Audiotec Fischer's DSP PC-Tool software, downloaded free from their web site.
Computer Controls: These controls are on the Helix PC-Tool software, downloaded to your computer from their web site (If a vehicle specific profile is downloaded, its settings cannot be changed using the PC-Tool):

It a perfect upgrade for my wife's 2015 BMW 30i, to covert her stock stereo from speaker outputnto line level ( RCA ), so she can have a better stereo envirnment. [ Timothy May 12, 2016 ]

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you. [ Krissy Jan 24, 2015 ] Staff
