ZapcoHB-410-ADSP 10 Ch. DSP / 8 Ch. Class D Amplifier

Very small and compact, not the most powerful amp by any means but the sound quality is amazing. I installed it in my Silverado EV and am pushing some very efficient Hertz audio speakers. There is absolutely no noise, the bass is extremely smooth and punchy, the highs are crisp and when listening to live music like Dave Matthews Band you can hear every note. The PC program is the best way to set it up as there is a flaw in the phone apps. I tried for both Android and IPhone. The issue is that when mapping the input channels to the outputs the phone apps do not match up and you cannot change a few of the channels. If this had a little more power and the apps worked 100% I would have given it 5 stars. I know this is not the Zapco of old from Modesto Ca. (Where I grew up) but I do recommend it if you are just looking for a clean amp for a basic upgrade. It will also make an amazing standalone DSP if I did want to run bigger amps later for more power. Hope this helps someone out. FYI this is an 8 channel amp even though the description says 4.
