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.

• Variable high pass filter

First class people, first class service, first class product!

Low Hertz is a lot more than a website. I know I could reach out to them if I needed anything.
No, not just with products. You can always count on quality. But questions about the hobby. Low Hertz is a movement in Car Audio. Where your not judged but helped! So get in the movement with us.

The last 3 box designs I've purchase were all 150+ db certified in the lanes, your results may vary depending on vehicle and power but they definitely know what they're doing. Well worth the money !

Eric Feliciano

They designed my husbands box. Came out great. Never a disappointment when it comes to these guys. Definitely will be coming back for another build!
