I've been having a weird issue with my sound system for my tsx. The car has aftermarket sounds(i can tell from the wiring in the trunk) but i'm not sure which, I bought the car like that.
Does anyone know what the problem could be? thanks

Every now and then the sound would skip like a cd skipping but I'm pretty sure its not the cd player because it happens on the radio also.

Another problem i've had is a weird scratching sound coming on occasionally.
