run a 4 channel amp for the speakers. here the speakers before you buy. it makes a different in the speakers you buy. run the speakers on there on channels that makes a big difference for sound.
if you are going to run the jl w6 subwoofer . that thing is a beast and it needs space so one of your back boxes are going plus you are going to need alot of insulation to sound proof that box. been there done that not need. look at the 10 inch jl tw3 slim you cant go wrong.
i am not into spending 300 to 600 on pods for the front. look at making something your self. and spend that money on some really good speakers like the focals, hertz, morels. all you need up front is 6.5 pair thats it.
one last thing if you want the highs i recommend the compression tweets by herts at 199. or just put in compression 3 inchers from jbl which will knock you out at how good they sound.
