Finally decided to sell the speaker box from my Ram, figured I would never be able to find another one like this, but I'll soon be getting a newer body style Ram, so its time.
I ran a JL Audio 10W6V2 woofer in this box which provided the perfect air space for a woofer this size. And yes it is cut for a 10 inch woofer. And in the pictures you can see it is an exact match for the dark interiors of the 03-08 trucks. The stain on the wood is from a water spill, there is NO discoloration on the fabric at all and it does not affect the performance or strength of the wood at all. All of the bolts and nuts required for install are included, and I'll throw in the speaker wire shown in the pics.
Any questions just ask. ~~ $100 shipped.
