I'm looking to put 2 10" L7 solobarics in the back of a 99 ext cab. I don't want to get rid of my back seat to fit a box for them. Anyone have this setup or know where I could find a box like that that would fit under the seat with those 2 subs?

 

i dont know how ur gonna do it but those are some good subs

 

your only option is to seat lift. even then it wont be a wise investment because solo barics are crap for sound quality and they wont have enough room in a box under the seat to get loud (assuming you dont care about sound quality)

 

What is the mounting depth on those subs?

 

i agree that you wont get a good enough box under that seat to do those subs justice however the comment on SQ is very far from true. with a GOOD and proper install the L7 can sound very nice. the problem with kicker subs is that they have received the reputation for only being a loud sub. so people buy them "kids" most of the time and toss them in crapy boxes with crappy power and the end result only ends up making the rep for sounding bad even worse. the sub has some solid specs and is very capable of sounding very nice in the right application
