the box came from a local/reliable stereo store. i was given a good deal on the box because i also bought two w3's. i think he charged me $50 flat for the box but you can get them normall for two 10's at about $80 dollars. I would rather build a custom box but hard to find the time. I was a little hesitant on the JL once both are hooked up, you realize paying the price was well worth it. i spent $190 a piece for each sub, although i shouldnt have been so impulse and just got them off the internet for like $160. considering you dont need much amp, you know its reliable and top of the line...in my opinion its worth the money. could maaaayyyybbbbee get w6's but afraid to adjust the bottom seat pan anymore, may become noticable.
next project: going to build a fiberglass enclosure that molds to the back seat floor from the sub box to the back of the center console that houses my new infinity kappa four amp that runs the infinity kappa mids. will have RGB LED's so i can color change...ill post pics but may be a bit. take care, peace.
