i need a box design that will fit in the back of a 09 g5 the max hight i can go is 16 inches and about 40 wide. it needs to fit 3 10" subs and be ported
in the wrong place ! most guys here can help you with a box , but the good designers that would give exact specs and cut sheet will prolly want cash for the design ,like myself .but we need to know what subs, and what tuning freq you want
