I have a 96 Maxima with the Bose system just a few months ago my audio shop added a 10 inch RS Self-Amplified Bazooka and Believe me it sounds very good. But my main problem is after I was playing the radio very loud I shut the car off came back a few hours later started the car and the radio wouldnt turn on! I checked the fuses and there both good. I was wondering if there is another fuse behind the radio or did I just smoked my radio?

 

The radio wouldn't turn on? Well, if the fuses are fine, it is probably the remote wire. When you get a sub installed, they tap into the remote wire. This wire tells the radio to turn on when the car is on. The stereo place may not have made a secure connection and it fell out of place.
