the kind ov box you make/buy will depend on the subs that you have, you will have to look at the manufacturer spec and recommendations, there is alot ov hard work to work out the perfect box sizes, again you can either check the spec for the subs and the recommended volume or goto www.caraudiodirect.com and ask for a bloke called efmax cause hes ment to be the daddy when it comes to box sizes/shapes etc, he charges bout ?30 for the sizes that the box needs to be but doesnt build them anymore
