Future Car Audio Setup

I've been wanting to get a system for my car for a while now, and I finally have enough money. I'm not really smart on audio systems, so i need advice on what im getting. Tell me what you guys think of this:

Panasonic CQ-DF602U Head Unit (http://www.crutchfield.com/cgi-bin/S-PdLNOhl9xuX/ProdView.asp?s=0&c=3&g=300&I=133DF602&o=p&a=0 )

California 600SX Amp (http://www.crutchfield.com/cgi-bin/S-PdLNOhl9xuX/ProdView.asp?s=0&c=3&g=110&I=489600SXK&o=p&a=0)
(I would go for the 800SX but its only 50 watts more and is several inches longer)

Q-Logic Box (http://www.crutchfield.com/cgi-bin/S-PdLNOhl9xuX/ProdView.asp?s=0&c=10&g=842&I=044H8512DX&o=p&a=0)
(I have to get a small box cause i want to save space in my trunk)

2 Sony XS-L1246 Subs (http://www.crutchfield.com/cgi-bin/S-PdLNOhl9xuX/ProdView.asp?s=0&c=10&g=67700&I=700L12462&o=p&a=0)

I am not a fan of California amps or Sony subs...

Sony subs!? :rolleyes: You can find better! How about Image Dynamics at www.sounddomain.com ?
Q Logic box!? I'm not a fan of particle board... MDF, much better!

Are the Polk Audio GNX124 a good buy if i can get them for less than retail?:flipa:

its just my opinion but get soundstream, rockford fosgate, or jl audio. Nice deck though. I have soundstream and JL audio and they are awesome. I used to have rockford fosgate and it was just as good. if not better

it all sounds good, except sony subs. i like the soundstream, fosgate, and jl suggestions, but would like to add eclipse and image dynamics, or if youre looking to spend a little less money, kicker.

also for the price af a q logic box, u could add just a little more and have your local sound shop make a custom box out of mdf, and it will be made to the exact size specs for whatever sub u choose.

hey man i got 2 10" audiobahn subs for sell , they will blwo those sony's out of the water only 150 for 2 in a box near-new condition
