Underseat audio.

So my truck came with a pretty nice audio system. A nice box with an amp and 2 ten inch subs that fit under the seat in the extended cab.

This was great until they got stolen out of the truck while it was at a body shop.....

So now comes shopping for a replacement. I would just replace the head unit but the previous owner ran the door speakers through the amp. So from the sounds of it it will be easier just to replace it then get rid of all that's been done.

Anyway, anyone know of a decent box that can fit a sub and amp under my rear set in my ECSB while still leaving me some room for under seat storage?

Thanks in advance,

John
