Review on 🔊 Powerful 800W RMS 4-Channel Car Amplifier: Polk Audio PA D4000.4 (PAD4000.4) by Aaron Vang

Just hooked up this bad boy it replaces the DUAL XPE4700 which I'm returning due to distortion at higher levels and so can't get anywhere near full power out of decent computer speakers. I built this block just like the previous one and there is one big difference! I'm getting every watt out of my speakers and it can be higher but my speakers can't handle it. I'm using a POLK db571 (50 watts into 4 ohms) on the rear and a POLK MM571 (90 watts into 2 ohms) on the front. Sometimes I like my music to be really loud, and this amp can do that and more. No wow what a deal.
