Amp whining?

We were going to take out a Clarion DPX11500 from my mom's truck and pair it up with an Fi BL. But recently it's been making a whining noise when you turn the truck on. It's only been happening on and off for a couple months though.

Any ideas why?

bad grounds somewhere could also be the culprit

i think there real i was looking through that guys stuff he sells and it looks like he finds stuff at auctions and just sells it

Yea, it looks like someone got the mids about a month ago....shit. If I had a whole Hertz front stage my ears would jizz all over my cheeks.

If it's nothing with the amp itself we should be good when we pull it tomorrow.

EDIT: Checked the grounds, nothing seemed bad. Wiggled the RCAs in some and the whining stopped. Hopefully it won't come back.
