nice car, looks mint, the jl looks good, i have had loads of w7's , i find the smaller the box the better they sound, i had a 12w7 in a box that was just big enough for it running of a 1000/1 and the sub blew it self out of the box it was that loud, i bought a jl box like you have and it didnt sound half as good when i put it in that!!! the w7's sound better in smaller box's , a loy more punchier .. i have a 8w7 in my van in the front and it is loud as for a 8" sub and that is in a box that it just fits in as well
