Key Features

Universal Sound Processor - Pioneer DEQ-S1000A2

The DEQ-S1000A2 is Pioneer's Universal Sound Processor, designed for upgrading the sound quality of your factory vehicle stereo and speakers. Since the originally fitted stereo does not need to be replaced, installation* is simple. Due to it's compact size, it can be installed out of sight, adding to a cleaner installation.

The DEQ-S1000A2 incorporates Pioneer's full custom high performance 48-bit dual-core DSP for high quality premium sound reproduction. An internal clock and pattern are optimally tuned. Sound degradation from jitter noise is thoroughly eliminated.

When used along with Pioneer's Sound Tune app, you can bring high end audio to the basic factory speakers. All operations are performed easily through a compatible smartphone and a wide range of settings are accessible from live simulation settings to 31-band custom equaliser settings via the Sound Tune app.
The DEQ-S1000A2 features easier connectivity thanks to the included ISO T-Harness and OTG cables for Android smartphone users. 
(*Optional vehicle specific cables may be required, sold separately).

Customer reviews

No good
Singh on 10/07/2020 2 star rating

Had this installed in the Nottingham branch, the sound was not massively improved (only slightly). Paid a lot of money for it and there is no noticeable improvement. The app is good though! I went back after a few days and after paying a fee, they removed the unit and installed the SRC6 by In Phase instead. MASSIVE DIFFERENCE. My car is an Audi A5 so removing the headunit and installing an aftermarket unit is a ball ache and expensive. So I will be back to have my sound system improved!

Not worth the Money
Mark on 12/05/2020 2 star rating

Having had this in my car for over 3 months now its has been back twice as its picks up a lot of interference. The App is not required as once set up I have not really tinkered with it.I have had too many issues with this and now will try the SRC6 as the reviews are good for that
