I have a lil problem. I just bought my truck and i wanna take the subs i have out of my other truck and but them in my new truck. i have no idea how to hook up my amp to my stock deck. ive heard its possible but i dont know how it can be if theres no RCA jacks in the back...is there an adapter? and does anyone know where i can get boxes that will fit under my rear seats?? thanks

yes there are adapters, best buy has them, and ebay seems to have a bunch of those undeat boxes.......

hey thanks alot. i found some sub boxes...i wish i had the blueprints i would just build my own. but i cant find the adapter at all for the stereo :(

it's called a line output converter

does anyone know where i can get the dimensions for it so i could build it myself or where i could find it for cheaper?

Custom boxes will cost you that much anywhere...

As for dimensions. Ever tried grabbing a ruler and measuring where you want to put it? Make room for excursion and just build it...
