MTX Loaded Sub Enclosure for Chevy Silverado / GMC Sierra Reviews

Customer Ratings:

While the shape and size of the enclosure is ideal for my needs ('11 Silverado) it leaves much to be desired. First off this enclosure is in bad need of internal bracing. If you slap your hand on the back of it the entire enclosure rings like a bell. Some internal braces imbedded into the fiberglass should have been a "no-brainer". Another issue I have is the cut-out for the sub. I replaced the MTX sub that came with the box with a Rockford sub. The mounting holes for this sub don't match exactly to the holes that were drilled for the MTX sub. I rotated the Rockford sub a few degrees and began to drill new mounting holes for it. I got to the third screw hole and there was nothing beneath the flange of the sub to drill into. I removed the sub and that's when I saw that the hole was oblong. COME ON MTX!!! You guys can't even make a round hole in this thing? Another issue is that there is only fiberglass to shoot your mounting screws into. Another "no-brainer" would have been to place a wood ring in the opening to shoot the mounting screws into. As it is you shoot screws into the fiberglass which pretty much turns the fiberglass into dust and doesn't leave much for the screw's threads to grab hold of. Once I managed to position the sub so that there was material beneath all the mounting holes I added some #10-24 T-nuts so I could torque the sub down good and tight. I also added some gasket material between the sub and enclosure to make an air tight seal. Finally there are only 2 points (one on each side) to secure the enclosure to the floor of the truck. This made for a very flimsy mount so I added a third bracket on the rear to make it much more sturdy. I'll keep this setup for now but once I have the cash I'll be replacing it with something better. Possibly a JL Stealthbox.
