hey, Im lookin into getting a custom box to go under the backseat in my 99 extended cab f150. any of you guys have one? if so what kind, what you think of them, prices etc? any info will be helpful. Thanks guys

 

i gotta 00 that is bagged... went with probox... 1000watt kicker and 2 10" kicker cvx's sounds great if you are tryin to rattle everything and still keep your back seat.. i really dont think it gets any bigger with a back seat...
