Head unit went out - replaced and still not working!

[LongThrow]

I have a Kenwood kdc mp238 and all 4 door speakers stop working. Then a week later the headunit itself turned off randomly which playing music. I checked all fuses and they were good. I went to Walmart and bought a 70 dollar jvc. I usef the existing spliced factory to aftermarket wire harness, and hooked it up all correctly and this head unit isn't working!

Could it be a problem with my factory wiring? And how would I fix that?

Yes... If they are burnt then the connector is bad. Either way you can always connect the wires directly to the factory wires.

Also make sure 100% that you have connected your headunit correctly.

Meaning wired correctly.

Factory wiring > spliced to aftermarket harness> connected to head unit. all wires are spliced to the correct color coded wire.

If there any problems with the wiring (factory wiring) how would that be fixed?
