Hi I have recently bought a 12" jl audio JL W3 sub and need a sub box to use it. Ideally id like a ported box but im not sure if you can get different sub box's with different depths and im not sure wots the best sub box to get the most out of the sub. Has anyone used this sub and wot box did u use. Does anyone know if bassboy makes sub boxs or buys them in and roughly how much would one cost basicly i dont know whether to get a box off ebay or buy one more specialised for the job?
