[QUOTE="HardofWhoring, post: 8856833, member: 674149"] I'm not really clear on your troubleshooting. It sounds like you checked everything. If you have door speakers playing right, your head unit is working and narrows it down to your preouts to sub. If you have a multimeter, check the resistance on the sub, (there $6 at Harbor). If the coil(s) read the correct ohm it's not the sub. Check the resistance of the sub speaker wire disconnected at the amp terminal end. If you hook up your multimeter to the sub amp's speaker outputs you can check AC voltage. Which would mean you have power, ground, and signal. Preamp outputs are not fused individually. [/QUOTE]
