audiobahn amps, if I am not mistaken have a rca output to run both the amps together doubling their output.
I would run a four gauge power wire down the left side of the car strait to the battery with a in-line fuse. The run a 16 gauge wire to the back of the radio for the remote turn on. Splice that into the blue remote wire behind the radio. Lift up the carpet in the trunk, use something to scrape a little paint off, and tap a ground their. Make sure you get the paint off to insure a good ground. Now purchase a distribution block, and run the power, ground, and remote through it. That will give you double of everything and just run those to both amps. Now all you have to do is run the RCS's from one amp to the other, and one amp to the radio. Now you are all set.
