I confirmed the resistance on both Jehnert underseats are 6.5 ohm not 4 ohm.

I did a few test with the underseat on the driver side, when it is connected to the amp directly in the trunk, resistance measured 6.5 ohm and works fine
when installed underseat, no resistance measured on the output wires from the trunk
I confirmed Technic's harness works fine, between the wire and metal connector there is current
Also confirmed the connection underseat is okay as well, measured 6.5 ohm resistance.

That tells me the factory wiring is broken at this point and that explains why driver side underseat stopped working all the sudden. Could it be too much heat on the OEM wire and burned the wire, can I investigate further? How to run new wire from trunk to underseat?
