175.4 beast

The dc audio 175.4 is a competition amplifier. Has plenty of power. A bit on the pricy side but looks sleek and performs well. Worth the cost

DC Audio 175.4

I would recommend the DC 175.4 if you have a power hungry set of comps or even a multiset of pro audio mids. I myself am using it to power a comp set of Focal 165 KRX2 and it makes them scream at almost no gain.

Wow what a beast

This thing is huge, built solid as a tank and even turned way down is making the mids and highs scream loud and clear.
