i wired in all the wires to my new radio and i turn it on.. it turns on and everything but no sound from the speakers? i put the old headunit back in and still no sound from the speakers... everything is wired in correctly thoguh, double checked everything.. whats the problem>?

 

is there a fuse blown somewhere?

 

Thats what i was thinking too. Check all the fuses. A test light should be your best friend. How did you wire the power for the new headunit ??? from the old power or is there a little inline fuse? ....is that blown ? ....how about on the side of your dash fuse ? ....if everything is ok start test lighting the wires , if thee is power going into the headunit , and a good ground, and still no sound. rip everything out and start over lol good luck !
