Pioneer’s DEQ-S1000A2 universal sound processor, is all that you need to upgrade the sound quality of your factory vehicle stereo and speakers or an upgraded speaker/amp combination.

The DEQ-S1000A2 incorporates a 4x50w internal amplifier (used if connecting directly to speakers), 3 x Hi-Volt RCA Pre-Outs (for external amplifiers) and is partnered with Pioneer’s high performance 48-bit dual-core DSP for high quality sound reproduction. An internal clock and pattern are optimally tuned, so sound degradation from jitter noise is thoroughly eliminated.

When used with Pioneer’s Sound Tune app, all settings, from the simplest, to the most advanced, can all be done intuitively and easily from your smartphone’s touchscreen.
