Problem with interiors

[LiL PiNoY]

When I play my music at a certain level the interiors go out. I think it could be the deck. It is a alpine cda9884. This only happens when I play CDs or I play my iPod but if I play the radio then it is fine. The deck is 4 years old and is mainly used for CDs. Has anyone heard of this problem? I doubt it is the amp because there a indicator light that tells me if something is wrong ( I use a 4*100 alpine pdx and the interiors are alpine type r's). I doubt it is the interiors as well because I play the radio as loud as I want with no problems. Please tell me what you think

Looks like its time for an upgrade.
