So a two cannel to power the subs and a two cannel to power the kickpanels is all that i will really need? Like i said i don't need a car show sound system, i just want to have a little more juice so i can thump when i need it to. What would you suggest for subs and amps. I have heard that MTX makes pretty nice subs and i'm not sure about amps. I am going with the speakers that comes with the kickpanels and i will buy either two 6x9 Infinity or Pioneer speakers for the back. But subs amps and head unit are still up in the air, i would like two get all three of these for about 600 dollars so I can save some money for more important parts on the car.
