Pioneer DEQ-S1000A Universal Sound Processor

The DEQ-S1000A universal sound processor sports 4 x MOSFET 50W amplifier, 3 x Hi-Volt RCA pre-outs, and a full-custom, high-performance 48-bit dual-core DSP – significantly improving the sound quality produced by factory-fitted receivers and can be installed almost anywhere in the car.

Sound Tune App

Pioneer’s Sound Tune app is a great way to bring the sound of high-end audio to a basic factory car stereo and speaker set. All operations are performed easily through a smartphone and a wide range of settings are accessible.


31-Band Graphic EQ

With Pioneer’s Sound Tune app, drivers are able to have full control over their car’s sound – with up to 31 bands of EQ available for adjustment. Pioneer’s Sound Tune app’s granular interface allows audiophiles to precisely zoom in to each band and adjust specific sections of the audio curve to their liking with a simple tap or a swipe of the finger.

Super Todoroki Sound

Super Todoroki Sound boosts low sounds and automatically adjusts mid- and high-range sounds to add impact and clarity to your audio environment.

First of all, it's a very small unit. I installed it in the glove box and it was super easy to wire to my factory radio. Easy to set up with my android phone and as soon I turn it on, the difference was night and day. Using my phone I was able to remove all low frequency from my doors speakers (factory speakers) and now I it doesn't distort at high volume. I'm very happy with this Pioneer DSP, and soon I'm getting a second one for my wife's car.
