Speaker Wiring

This can go a couple of different ways, but my suggestion for just ease of the install is to leave the OEM wiring where it's at and just connect your speakers straight to the OEM wiring. Then run your speaker wire from the harness to your amp. Connect the RCA's, set your gain and voila. (For a tip on setting your gain you can check here...Rockford T212D2 too much for 370z?

Also, yes you would run your door/dash in parallel.

To clarify for me and the OP, you suggest RCA from Radio to AMP, then speaker wire from AMP back to radio harness up front. Thereby eliminating the need to rerun wire to the speakers. Is that correct?

Sorry to bring this back from the dead...but I'm a bit confuse. So you would connect the oem wire to new speaker (using appropiate connectors). Now keep the oem wiring connected to the oem harness-->connected to metra harness-->connected (with connectors) to Kenwood harness-->connected to the 7140 unit. Now how would I connect the speaker wires from there to the amp? Thanks!

Sorry my man I am going to have to disagree on that one. The amp is probably going to out out around 50 watts to the spakers, the factory wireing is not rely made for that. Also you would get less resistance in the flow of power if you installed new wireing in the doors. It will take some time and you will have to drill a hole in the door but it is possible. The new speakers need the crossover that has come with them. That way they are being fed the proper freq and such. I would run new wire from the amp to the crossover than form there to the speaker and the tweeter. This is all on the theory that you are running components up front.

On a side not you can still use the factory wiring I just recommend upgrading.
