Radio / speaker problem

The other day i was in my car listning to the radio. and i had it up pretty high suddenly just tonight there was no bass?? i know the speakers arent blown because ive had that alot. but i crank the low end bass up and you can just dimmly hear it like the bass is completly off? would it be the stock deck or speakers or maby wiring..... help me out guys

Hmm... I'd guess the stock deck is shot. I'm no audiophile, but I'd say you'd be better off to just get an aftermarket CD player vs installing a stock tape deck as it will help the overall value of the car.
