Im going to run 2 12's underneath my back seat in my 03 silverado. in order for the subs/box to fit i need to raise the back seat 4"

anyone know where I could buy a kit? or know of anyone that makes and sells them on the forums?

any help will be appreciated.
thanks

 

go to a local place that does interior work..or somebody who re-covers seats..they might make u a custom box out of your stock seat....also a place around me called car stereo one...they sell seats like i just mention for i think $350and they custom build the box to however u want

 

hey thanks for the help bro but i ended up just making two brackets yesterday at work, so now i just need a shop to build me a box.
