radio problems

[jeepster_23]

for some reason all my speakers in my truck quit working but the radio is working fine. they where all working fine early and all of them just quit.

is it a aftermarket radio or stock. if stock does it have a internal amp. if it has a internal amp it might of blown a fuse or blown itself.

[jeepster_23]

its aftermarket. i checked the fuses and they are all good

[Squirell]

what truck is it in? next step would be, take radio out and hook a speaker up to a output and see if you got sound, also if you have preouts they may be grounding out. which would cost sound lost. what kind of radio is it?
