My front speakers sound great. But while replacing a taillight, I noticed that my subwoofer is not contributing anything.
So I set out to investigate.
It is receiving power. The speakers are moving *slightly*. But not enough to really produce any sound.
I checked the voltage on the orange signal wires. I have an analog multimeter, and sometimes you can see the needle move with the signal.
But since it is line level, I really couldn't tell much.
Also, I pulled the head unit (had to fashion a tool from an old, small hacksaw blade, but that is another post) and reseated all the connectors.
Still, front has lots of bass. Subwoofer has nothing. Even with the fade set to full rear and subwoofer set to +9, nothing.
Anyone have any ideas?
Do the amplifiers go bad in these things? How would I tell?
Could it be a low signal from the head unit?
Does the wiring go straight from the head unit to the subwoofer? Or does it take a detour through the front amps or rear speakers?
Thanks to anyone that can give me any guidance.
