I Installed a new 300/4 JL audio amp and having some problems with the front right channel on the amp. I wanted to verify the amp was fully functional so I wired a speaker and checked each of the 4 channels.
All the the channels worked perfect expect for the front right channel. When hooking up the speaker to front right channel I get a loud screaming high pitch sound that will almost make you deaf. Sometimes a little music comes through and pops a few times and then that death ray sound comes.
I don't want to take back the amp until I am sure this is the problem. Anyone familiar with the symptoms I just described. Sounds like a bad channel in the amp to me? The speaker worked in all other channels expect for the front right channel. Is it common for JL audio amps to be defective like this?
Sounds like you already know what's wrong with it, and from what your saying, yes, that channel is blown. Take it back ASAP. Don't play around with something that isn't working right, and also don't hook anything else up to that channel, usually when 1 channel goes bad, the others are sure to follow. Have it checked at your earliest conveience.
Rcas were changed out several times no difference. The same set of speaker wires and speaker were used on four channels when I tested it. The other three channels works fine with the speaker. So it can't be the speaker wire. It can't be the RCA because I had the amp on two channel mode and the rear right channel would be defective as well if the RCA was bad. But I did change the RCAs. Has to be the amp I am convinced nothing else.
