2001-2013 Chevy Avalanche Sub Box Ported

The 2001-2013 Chevy Avalanche offers it’s own unique disadvantages and advantages to stereo systems that can give unlimited potential for output while also leaving the truck usable as a work vehicle. This box was designed to take place of the factory midgate and allows you to get the bass you want while still being able to use your truck as a truck. This box is the maximum workable height and width to get as much airspace as possible so that the box itself doesn’t have to be that deep. It can be built up to 16″ deep and still fit in the back doors for those big bass situations. This box can accommodate a wide combination of 10s, 12s and 15s in this ported configuration. It is made so that the factory latches at the top can be installed and locked into place and the bottom is made to screw into the midgate hinge brackets. This enclosure comes standard carpeted, but my preference and recommendation is to let me spray it with my black NET Liner to protect it from the elements and allow you to use your bed worry free. We can also carpet the front of the box and spray the rear. Let me know if this is what you want to do and we can discuss the options. This box will loose the factory rear window storage.

To install this box, the flap at the bottom of the midgate needs to be removed and the midgate needs to be unbolted from the hinges.

THESE BOXES ARE ALL CUSTOM MADE TO ORDER FOR YOUR APPLICATION. THIS IS NOT A ONE SIZE FITS ALL BOX, IT IS A FULL CUSTOM BOX AND NONE OF THEM ARE PRE-MADE AND SITTING WAITING TO BE SHIPPED OUT. THE PORTED BOXES ARE ALL MADE FOR YOUR SPECIFIC SUBS TO GET THE MOST OUT OF THEM POSSIBLE. IF YOU HAVE ANY REQUESTS, FEEL FREE TO LET US KNOW.

Because this is the smallest box we offer for the Avalanche the mounting depth is very limited as well. The mounting depth is 4.08 inches but can be a bit deeper with our metal back plates that we offer. The back plates will allow for an extra 0.75 inches of mounting depth for a total of 4.83 inches. This box is meant for shallow mount subs and to take up the least amount of room possible from the bed area, but some traditional subs will work just fine in it. It has 1.6cuft of total airspace, which is enough for a single small or shallow sub ported.

This is a ported subwoofer box. Ported subwoofer boxes are for customers who want louder, deeper bass with the lower bass more pronounced. Because of the ported design, the bass will not be as tight and punchy as a sealed box, but there is double the bass of a sealed box with the same subs. A sealed subwoofer box has a tight and punchy bass that is more articulate and more true to the music with a more natural sound. If tight, punchy bass is what you want then our sealed box will be what you want.

This box is made out of 3/4″ MDF and is fully carpeted in matching carpet. The nickle plated spring loaded speaker terminals are mounted on the back of the box and the speaker wires are soldered on for a solid and reliable connection.
