Sub Box Dimensions

[redrocket]

just wondering if anyone knows what the dimensions would be for the biggest possible sub box to be where the jack mounts behind the rear seat? i see a few people have done it but i cant seem to find the dimensions they used. Thanks!

I've been looking at the loaded kicker rt shallow truck box and sub its 3-9/16 at the top and 5 or 6 depth at the bottom only 13ish tall I did the blazer leather seat swap front and rear on my CC so I'll have room to spare but I think it would fit... Bottom will with stock rear bench dimensions wise top will be tight with factory but you could always unbolt the seat and put a few washers on the bolts to give the clearance you need
