i got two alpine type e's in a bass works ported box and they sound great. But all u guys say if u can get a custom one built subs always sound better. So how would i go about figuring out how to design a box with ports?

first off search in google for an enclosure program that will get far you type in your pax dimensions and what you want the box tuned to and your subs and then it generates a os for you

i would upgrade your subs if you are going to pay alot for a custom box

My old opinion = don't mess with what's good you like your boom car box how it is leave it upgrade other areas, its hard to get a box right, if I'm not mistachen you can pay some one on this site like 10$ and they will completely desighn a box for you?

BMW is right man, upgrade the subwoofers...the custom box would cost more than the sub...type e's aren't all that great either...my girl has 3 and compared to my one sub...cant match

A box built by yourself will usually cost about $40.... Cheaper than two new subs.

Try to make the box about 3 to 3.5 cubic feet, with around 50-60 square inches of port

EDIT: If you want a hand with a design just let me know.
