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.
