Great amp

I have this on 5x7 Polk audio door speakers in a 2008 Ford explorer. Delivers clean power to my speakers and I can adjust rear gain to balance my system rather than using my fader. No overheating issue and it's in a fairly enclosed space. If u want compact size this is not the amp otherwise it will be more than what u hoped it to be
