No problem. I can't design the box for you without a purchase, but I can get you some basic info for it.....and only as a basis.....volume, tuning, and port size. But if you want me to design it also, let me know. I can add vehicle gain, proper phase correlation with port and driver baffle direction, increased efficiency, proper driver control, etc....the works. If not, the recommended will give you a good start. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
