currently got a cd player from halfords with the out put for my sub, which is the 2000w fly double sub....this cd player is new the sub ive had for a couple months, for some reason my cd player occasionally cuts out, and i need to give it 5 mins before it works again, could this be down to an over heating problem , or a fuse, ive checked the fuse box in my astra and that all seems okay. whether i need to buy a new cd player as ive lost my receipt and halfords are hopeless. please help
