[GMB Racing]

I'm looking to see if anyone has the wiring diagrams for a GT w/a400 and a401 audio options This will allow me to figure out what wiring differences are.

thank in advance

Somebody please correct me if I'm miss-stating this, but I believe that the a400 is the 9 speaker Shaker and the a401 is the 12 speaker Shaker Pro.

The difference is that the Pro adds coaxials in the rear deck and a subwoofer.

As far as wiring, the a400 system does not have the subwoofer wiring in place.
