Performance Teknique ICBM-775 4 Channel Amplifier 500W MAX [Electronics]

here's another that I have for a little while now I actually didn't purchase this I got this for free it was found in the dumpster at one of the stores I used to service back when I was working my last job so I took it home hoping it would work it actually does work it's just there's a problem with this right here if you can see that positive block but if they see all that like bubbling on the plastic and all that fun stuff gets worse on the bottom side right where's my hand right I don't know there it gets worse something happened with it and I think it causes a short wall not really a short just like interference with the remote wire because the amp doesn't turn on or doesn't turn off once you plug it in even if you have your remote wire on a switch to relay it stays on and you get wacky voltage tried installing this and didn't work out too well so I had to pull it out it works fine a
