I highly recommend running new wire with proper terminations. You owe it to yourself. Knukonceptz makes really nice speaker wire that is well priced. You don't necessarily need bigger wire than 16 gauge for components, but for subs, I recommend 12 gauge wire. Ordering two different lengths of gauges will save you money. You can simulate the length of your runs with string and duct tape to hold it in place to get an idea of how much wire you will need. It could be a fair amount, depending on the vehicle and distance from the amps to the speaker locations.

Electrical upgrades are recommended. At least upgrade your big 3/4, but a new alt and more batteries never hurts if you plan on supplying steady voltage and current to a big ass amp that is pushing those monsters..

Just a thought. Consider gluing strips of sturdy wood to the floor before you apply the D pro, then put D pro everywhere else. I have had success doing this with strips of oak and PL adhesive. Then attach your amp board to the strips of wood that are glued to the floor or wall metal. This will allow you to avoid drilling holes in your floor. If not possible please disregard.

All this suspense got me rollin' in my grave.
