Wait, I take the junk back... The amp quality is great, but if you ever blow one and send it to get fixed.... You better be prepared to wait unless your a team member!!! My buddy sent two amps back to get related, a colossus xxv and a Sampson.....they both got shipped off around the end of DECEMBER 09' .... They had to completely rebuild the Sampsons board for him because they said they couldn't get the parts to fix it.... The amps not that old and they don't have parts???? So finally got that fixed and got it back a couple months ago... Yeah, 7-8 months later!!!! And guess what? STILL DON'T HAVE THE COLOSUS BACK!!! They are giving him the constant run around on it.... So needless to say ALL the hifonics stuff has Been pulled out and sold... Running nothing but good ol' Sundown Audio now
