Ok, Im going to put 2 Massive Audio P1500d, and 1 Kicker KX800x4. My question here is what type of electrical system work needs to be done. Here is what I have in my 97 Ford Explorer. I recently had a Autotek MX5000, and the same Kicker amp mentioned above. The Autotek was pushing [4] kicker L7's wired at 2ohms, doing 2400kw. I had it installed at local shop here in miami. I have 2 guage wire from the front to the back for my power line, same for the ground wire, also have a Redtop Bat in the rear by my sub box. None of the wires have changed sinc the insatll was done, but adding a 3rd amp, do i need to add another red/yellow top batt, or would my setup take on 3rd amp the way it is. Any help here would be greatly appreciated!!
