So my car (03 Z) was at the dealership and they told me my battery voltage was very low. The battery is quite a few years old so I told them to just change it out. On my way home I noticed that my 10" woofer is not working. I went in and reset all the settings on my deck and even checked the cables from the battery and everything looks fine. The power light is even on the amp. Of course the dealership is playing the "we don't know anything about that" card. Any suggestions on what to do or how to troubleshoot?

 

Your gonna have to trouble shoot from the batt on back its most likely a loose connection
or they could of shorted out something so check all your fuses also

 

grab a dmm, test light, or probe and see if your getting power out of your amp to your sub...just troubleshoot til you find the problem

 

Check the fuse

 

It started working about an hour after I posted this. All connections were solid, fuses were good. Could it have been capacitor related?

 

check the remote wire.
