I have a 2400watt concept amp for a aw1508q audiobahn sub, it is too big so im only putting in the component system if i can. This is my situation, I want to put a ppi 400 watt bridged 2 channel amp in my 2k maxima to play audiobahn abc6003q component system, but i want to run off the stock deck to keep a stock look. What do i need to put this system in my maxima? The components consist of 6.5", 4", and 25mm tweets, and are 3 way comp, and have a passive crossover network, whatever that means. I have heard the 4" won't fit, but cant i just cut some mdf to mount like i read in one of the posts? Thanks A LOT for the help.
