Does my amp need to be repaired/replaced??

[Alimoose 10+ year member]

Recently got my car finished with everything installed and playing, but there was horrible ground noise coming through my mids/highs.

Removed the RCAs and the amp (MB Quart Onyx 4.125) went into protect. RCAs plugged in, the amp stays on fine but there is horrible ground noise. Also tried an RCA to AUX cable to play from my ipod, came on for 1 sec and then it went into protect.

Before all this ground noise, we did find out that my Crescendo XST2's terminals were all apart and what not (how the hell does a speaker fall apart?!! same thing happen to my other XST2 and same with my friends) and it was grounding out onto one of the bars on the trunk lid, causing all my mids/highs to pop extremely loud.

Any idea?

A speaker grounding off the chassis is VERY bad, i would go as far as saying the amplifier could be fucked

yea, sounds like some internal components failed on the amp.

Hmm... alright, thanks. I'll see if I can get a warranty repair/replacement. Didn't mention the part about it grounding out on the chassis to them though lol.

will the head rcas play good on another amp? could have popped a pico fuse or ground/noise strap in the amp, or head.
