ok a little back story on this. Great amp, strong and worked flawlessly for me. Sold truck, pulled amp took pics and put on ebay same day i took it out of truck. Mind you was working fine a few moments before i pulled it from truck. Anyway sold and shipped to Cali. guy gets amp and swears it smells burnt etc. He can't get it to play for him and just send a loud whine through his subs. I call bs on him a few times:verymad: but ebay does not protect a seller so I got it sent back and refunded the guy. I got the amp back and I can't find anything wrong with it, no burnt smell as he said. opened up the board is clean as can be. only thing i saw was the mounting tabs were bent up to the point of touching the rca input which prob gave him his loud whine. I have no need for this and obviously can't 100% say whether it works or not(haven't tested) but if anyone wants good power for cheap i'll ship it to you for $175obro . it's taking up closet space and if it is bad prob would't be too bad to fix. can send pics if reqested. pm me
