If you’re looking for an amp that puts out crystal clear audio at very low cost to you, then look o further. I have this guy strapped down on 8 American Bass SQ speakers and it doesn’t matter whether I’m on 10 or 40, i get zero distortion with a very adjustable HPF. I’ve been a professional installer for 4 years and have yet to find anything that’ll get you as loud as SSL products. Especialy at such a low price range. There are many expensive brands that cant even compete with these guys.
