Title
A single-sub box for the 2014 GMC Sierra 1500 crew cab that mounts on the driver side under the rear seat. It takes one 8", 10" or 12" subwoofer with 0.75 cubic feet of airspace, and it also fits the 2014 Silverado 1500 crew cab and the 2015 Silverado crew cab.
| Subwoofers | One 8", one 10" or one 12" |
|---|---|
| Airspace | 0.75 cu ft |
| Mounting depth | 6" for 8s and 10s; 5" for a 12" |
| Cutouts | Standard 7" for 8s; 9 1/8" for 10s; 11 1/8" for 12s |
| Construction | MDF, CNC cut |
| Terminals | Speaker terminal included |
Some subs have magnets too large to fit this box well, so the sub model matters here: type it in the "What Sub Model are you using?" box when you order so the match can be checked and the box cut to suit. Check the depth for your size (6" for 8s and 10s, 5" for 12s) and the cutout; a sub larger than the specs may not fit. No sub yet? Call for a suggestion. Shop 8" subwoofers, 10" subwoofers or 12" subwoofers.
Built to order by Xtreme Enclosures: CNC cut from MDF and professionally constructed. Estimated lead time: 20–40 business days.
