I also have a Regular Cab S-10 and Im looking on some ways to build myself a box or atleast find a place that sells boxes that would fit in my S-10. I am gonna be running 2 Mtx Thunder 8000's but 1 for now till I get myself some more money for another sub. I looked for custom enclosures but they are $250 for just one. Anyone have any designs, boxes that would go good with enough and alot of space, or places that sells the custom enclosures for cheap? Thanks
