I have a 99 f150 extended cab P\U I am looking for a subwoofer box for under the rear seat. I dont know weather it will be better to build my own or to buy one. I dont have any subs picked out but I was thinking of using 2 10's. Id like to do this with out spending alot of money. If anyone has built there own box for these trucks could you send me some pictures or if anyone can help me get a desent inexpencive box that would be great. Also some help on picking out the subs would be apreciated.

Thanks

I bought my box off of ebay for around $70 shipped, you will want a 10 that works well in a small box .5 cubic foot or so and a mounting depth not over 6"

5 3/4" mounting depth
~ .6 - .7 volume (per sub)
