Description
The 175.4 competition series amplifier is a 175 watts per channel @ 4 ohms or 250 watts per channel @ 2 ohms. It is not 1 ohm stable. We know alot of our customers love their low end ground pounders but want their mids and highs to keep up. That's why we offer such a large 4 channel amp.
We believe that "Overkill is Under-Rated". For power inputs it will accept 4 awg for power and 4 awg for ground.

4-channel amplifier
Plenty of power and the best quality for highs I've ever ran. I have been building my own systems for over 25 years. Right on :)

DC Audio Class A/B 175.4
I have 3 of these DC Audio 175.4 and they sound excellent. I'm charging at 15.3 - 15.5 and they put out great power. I have two running at 4 ohm and one running at 2 ohm. The 4 ohm amps don't even get warm. The 2 ohm amp does get warm but it doesn't get blazing hot and go into protect like most A/B amps. The quality is definitely there. Class A/B amps are the best sound that you can get for mids/highs. Lastly, Down 4 Sound is great to deal with. They get it to you quick too.
