I had a Pioneer head unit and Polk Audio speakers installed ('05 Base xfire, no rear speakers, just in front doors) about a year and a half ago. Everything has worked fine up until recently. Out of no where I lost sound in my speakers. I have to crank the volume all the way up to hear anything and what I can hear is faint, distant and has static. I was told I probably blew a channel on the head unit so I installed another and still have the same issues. I hooked a home speaker to the Pioneer head unit and it worked perfectly. So with all of that being said I know its not the head unit. So the question is...what is it? Speakers? Hard to believe that both speakers went bad at the same time. So next would be factory amp, except I don't think the Base model had a factory amp. I could be wrong but so far everyone says its under the passenger seat. So I took out the passenger seat and pulled the carpet and found nothing. Not sure what to do from here. Something is messed up between head unit and speakers. HELP!!!

 

Welcome to the forum! It's not under the passenger seat, but under the passenger side carpet closest to the firewall. I'm not sure if the base models had an amp or not, but if you have one, that's where it'll be, you'll pull some carpet back, then some styrofoam, then you'll see the amp. But with the speakers...since you CAN hear them, even though very quiet, i'd doubt they're blown, as you'd hear either nothing at all, or it'd rattle like hell. I'm going to guess, along with the static, that at some point your speaker wire was getting pinched, possibly in a door, under the floor, in the door jamb possibly...and they've gotten to be exposed metal, which could cause a ground loop.

But a busted amp does sound like a reasonable cause, try hooking the speakers up directly to your head unit and see if they work. The reason this may have happened, if it did. Is that you're most likely running a high level input through an amplifier that's designed for low-level. Gives you some extra volume, yes, but also creates crazy amounts of "clipping," which kills amps. If you look and see that you DO have an amplifier, let me know, as I have one I could sell you for cheap, they're hardly ever on ebay these days, and when they are they're like 400 dollars IIRC.
