I installed two 6*9s and two front xplodes to my 97 grand prix se and alout of nowhere the rear deck starts chiming in and out then just stops working the speakers are still good I was just driving down the road and it happened. I also only have the 6*9s on the deck. The fours are snipped and blown. Help. Wires are good and right the fuses are good. And I think the amp is good Idk what to do I'm livid.
