Avery ★★★★★ Oct 22, 2026

Finally got this wired up in my truck and the 9.5 volt RMS output gave my system the clean boost it needed. I especially appreciate the input signal summing per channel pair, which simplified my factory integration. It’s a solid DSP upgrade that works exactly as described.

The dash remote is a game changer for adjusting volume and bass on the fly without reaching for my phone. Even with my factory head unit, the 9.5 volt output cleaned up the signal enough that my amps finally sound crisp.

Finally got my bass back without losing any clarity from the factory head unit. The dash remote makes it super easy to dial in the volume and bass recovery on the fly.
