Question about Audio Players & Recorders
Check all connections for bits of wire that may short out, and check the way the wires are run to the sub, they maybe crushed by something they run under like a seat etc. Also your subs may be cooked. This is easily checked by carefully pressing on the sub around the the center hub with a 'clawed' hand (so that your fingers are evenly spaced and you press evenly straight inward), if you hear a grinding noise (like there's sand in it) or if the sub dosen't move at all then it's destroyed.
Let me know if this helps.

You need to check the DC voltage across the B+ and ground terminals. You also need to check the DC voltage across the remote and ground terminals. If the voltage is less than 11 volts, you need to check the B+ supply and remote wiring for breaks or open fuses. You should also check the ground connection to confirm that it's not loose.
If the voltage is OK, the output transistors are likely shorted.
