Faulty amp?

[Ninja_Turtle 10+ year member]

I have a two ch. profile CA amp and all the sudden it has been causing my speakers to make a annoying engine whine noise. I try using hooking up different RCA to it and it immediately shuts off . Its grounded to the vehicle's chassis ( same place my subwoofer amp is) so I don't think its a bad ground. Could it be the amp is broken??

There's a thread on here about how to ground RCAs. Not sure how accurate it is, but it is said that it tends to happen when you mess with RCAs while the amp/HU is powered up.

The rca's are grounded to the HU. The whine only happens when I hook up the Profile amp to the Front RCA. I can hook up my sub amp to my front Ch. and no whine.

if u got a portable music device and a 3.5 to rca adaptor plug that into the amp and see if the noise is still there.
