Try this sight. He will design based out your vehicle and what you want to get from your subs, i.e, SQ, smooth roll off, SPL. He will even build and ship it. With those 12W3, you need 1.125 sealed and 1.75 ported tuned I'm assuming in the low to mid 30's. You might be able to find a ported enclosure around the 1.75 but the tuning will be in the mid to high 40's (mostly). You can always call a local cabinet builder and ask if they can help you. Be a lot cheaper than having one shipped. JL is pretty spot on with there enclosures. Worse case I'll build you a box and ship it to you for the cost of the wood and shipping (I'm a carpenter, tools and a cast understanding of wood I have plenty of). We all deserve good sound. :-)
