Rockville RSST12 0.9 cu.ft. Sealed 12" Car/Truck Subwoofer Enclosure, Shallow Mount, 5/8" USA MDF, Made in USA, Compact Design for Tight Spaces

Fits right in the truck of a car.

Filled with 1lb of Poly-fil then added a JL12W1V3-4 in it. Sounds great! Installed under 2013 F150 Supercrew seats.

Bought this for a Kicker CompR 12 inch sub with a 5.75 inch mounting depth (48CWR122 is the model i think) and the hole fits but sub doesn't go down all the way, if you remove some material on the back side it will but it doesn't have the marketed 6in mounting depth for anyone who was looking for a plug and play box, slight modification no big deal, decent box.

Details claim it would hold any shallow mount sub on the market up to 6 inches deep. I have a Kenwood with a mount depth of 5 13/16 and it doesn’t fit. Had to buy and adapter ring for it to work.

Perfect fit - Rockford Fosgate R2SD2 sounds great

I would buy this again, if I had to.This thing is solid, and it fit my speaker like a glove

It was a faulty box.. letting air out of box. Asked for a refund. Sent item back and still waiting on refund.

I ordered this box to house a kicker 12" sub. The box was to small to house the subwoofer so i had to return it. BUT BE AWARE: If you return it they have a 10% restock fee, and you have to pay return shipping that costed me $35!! I should not have returned it because I actually list money buy returning this item....just make sure this is the right one for you before you buy it, and if you need to return it. don't waste your time returning it you'll lose more money.
