Just got a 2011 ram 1500 with the alpine sound system. The door speakers all work and sound great but the sub under the back seat does nothing. Tested the sub with 9v battery and it works. I'm lost

If the sub works then check the speaker wire.....is there a short? If the wire is OK then look to the head unit for output.

All the wire I could see looked good. How is the best way to check for output? I'm not very good with this kind of stuff I just hate it when things don't work. Is there only one fuse that powers the amp?
