Stock amp ground wire

[Mitchell21]

Lately one of my speakers sounds fuzzy and when I turn the volume up for a while it will cut in and out then go out taking the other speakers with it. Comes back on after I turn the car on again. From what I’ve read it could be a bad ground on the amp, so does anyone know how to access the amp ground wire? (It’s got brand new speakers so it isn’t blown)

Honestly, I would go into the trunk and take a small mallet and tap the D.S.P.

What year car do you have. And just to confirm, you have sony Audio?
