Help.. Squeal/Howling from Amp

[DetoxLS 10+ year member]

I have an amp for my door speakers. There is a howling noise that comes from the speakers.

The power cables are not close to the RCAs. However, if I unplug the front or the rear RCAs leaving one set plugged in, the howling dissapears totally.

When they are all plugged in, it sqeals.

Should I get the best rcas out there to fix the problem?

It kinda sounds like the RCAs are pinched or punctured. I'd check the rca wire and see if its in good shape. Also, check to see if its one particular rca jack or output from the radio that is causing the noise. Change the connections around and see what happens.

If it was punctured wouldnt they always sqeal? They both dont squeal until all of them are plugged in.

It'll do it if one of the plugs wires was messed up. If the rest of the wires are okay, then it'll only do it if all the wires are plugged in.
