Bad Amp?

[Dual L7 10+ year member]

Im new to this forum and have a question. I have 2 12" kicker L7s being pushed by a Lanzar 2ch 4000w amp. I woke up this morning and got in my car to go to work and my subs just started poundin. I turned my volume to 0 and it just kept poundin. Im thinking that my amp is bad but I wanted to know if it could be something else.

I will try grounding my RCAs today. Its just weird because it was working fine and then the next day it started happening.

Bad RCA's in the amp. But possibly bad RCA grounds in the headunit. More than likely in the amp.

Do you think that I should trying replacing my RCAs or maybe try a ground loop isolator?
