Sold FS: US Amps AX4300 - one channel not working

[mysilver02alty 10+ year member]

I bought it on this forum but one of the channles does not work. Basically one speaker works and one does not. If you switch the rca cables, the other speaker works, but the first one does not.

I dont know how to fix amps but maybe one of you guys do and can do it easy. One of the mounting holes broke off. Maybe you can glue it back on i dont know. One of the 4 channels does not work. Im no amp expert so i have no clue what is wrong with it.

I cant use it unless i just use it to power my rear speakers so theres no point in me keeping it. Its got about 2 hours of play time on it and its in perfect cosmetic condition other than the top right broken mounting hole. I guess you could use it as a 3 channel amp if you have any use for one of those. The other 3 channels are in perfect working order. Maybe you use the one working rear channel to power 2 rear speakers or a set of tweeters with 37.5 watts each. Im no install wizzard so i dont know. I heard these are underrated but im not a big expert on US Amps products either.

Make an offer.

If you swap RCA's and one side works then something is wrong with the signal going into the amp not the amp itself.....

Hes saying swap the RCA and see if you hear sounds. If you do then its not the amp

Im a little confused. The guy at the audio shop today said it was the amp.

Heres what happens:

rca 1 goes to left rear

rca 2 goes to right rear

left rear works

right rear does not work

if i put rca 1 into the rca 2 slot and rca 2 into the rca 1 slot:

right rear works

left rear does not work

You think maybe the hu is messed up?

Lawls, I think you owe asaner85 an apology.
