my 1988 f150 is havin some problems with the wiring or fuses.

i just got a new jvc stereo and pioneer speakers to put in, they were working great. but then i went through a carwash and they just stopped working. this has happened before, but all i had to do was change the fuses. this time all the fuses are in perfect working order, none of them are blown or anything.

could this be some wiring issue? or is it the stereo?

sorry if these questions are dumb, not a very good wiring guy:P

 

Your going to have to check your wires for power. A test light will help but a multimeter would be better. If you don't have one you can pick one up from harbor freight for free with a coupon. You should have one lead to constant 12v from the battery one that supplies 12v when the key is on accessory or run and one to ground. No other wires should register ground. You may also have a fuse in the radio harness or in the radio itself.
