what should i use

what kind of box do you recomend to use with two jl w6's because the recomended one they gave me won't fit in the trunk. i think they recomended it to be 40x28x35.50 with four 2.5x13.6 ports and i know this won't fit in my civic.Also later on i was thinking of doing a custom fiberglass enclosure in the spare tire well and was going to put three in there. can i just use the shape it gives me as the size then maybe add longer ports to compensate for the lost vloume. does anyone know any tips on how trick a .88cubic feet or a 1.25cubic feet box into thinking that it's a larger size(you know what i mean). ex : adding longer or larger ports, stuffing or loading the box with something, you know shit like that. thanks in advance

can anyone please reply

I had the obcon box for my 12W6s. :)

Polyfill can only do so much... 10% increase of volume/space...

i say save your money from the box and built custom poly. looks nicer and definately will sound better.
