Logic 7 amp wire to under seat sub help

sillygoat · 12-02-2010, 08:53 AM

My left sub under the seat isn't working. I think I might have jacked up one of the wires from the sub to the stock amp when I installed an aftermarket sub a while back. Any way to replace one of these wires?

If so anyone know the Size of wire?

Most likely that the wire is fine. Probably the connection at the speaker, the speaker itself, or that channel of the amplifier. One of those 3. However, it is unlikely that the factory wiring has broken somewhere along its run. That is a VERY rare occurrence. It is possible to replace the wire if found to be bad. Just run a new speaker wire from the amp output to the speaker, it'll suck. But be 100% sure that is the problem before you take the car apart to run it. Check the connection first. If that is OK then place a "test" speaker in it's place to make sure you are getting signal. If you are, then run a "quick and dirty" wire from the amp to the speaker from the outside of the car to get a signal. If that doesn't work...look at the amplifier itself.

^^^ what?

I am guessing you broke a strand in the OEM speaker wire when you tapped the signal for the aftermarket amp & sub. You should be able to repair it easily without having to run any new wires...
