I have a chevy s10 truck and believe it or not, but i was able to fit two of these in here, had to do a little this and that to my truck, but they fit! two L7's sound very nice in here! have em hooked up to a hifonics 2400.1 amp. I did have two cvr's, but you know how bass is, very addicting. you always want louder. So if you have a small truck, and need L7's this is the box! By the way the Length is 23 1/2, the height is 16, and the bottom width is 9 1/2, and top width is 6.
