This box is very similar to our Dual Downfire box.†

If you†own a new 2015 Colorado or Canyon pickup, you already know that there isn't much room left over for subs.† The space under the rear seat is very restrictive and doesn't allow for much in the way of subs to be installed under it.† But we managed to design a box to†fit under the seat†that will hold a 10" sub and have space left over to mount your amp on.† This makes for an excellent install that is both clean and nice-looking.† Like our†dual box, this box also†requires you to remove the plastic shield and support bar under the seat.† But don't worry because the box is the perfect height and the front of the seat rests firmly on the box and locks into place like normal.† Because of this, the box is actually held in place nicely by the seat and doesn't move a bit.† You will love how this box fits and sound in your truck.††

Please note that not every shallow sub is going to fit in this box.† We will try to list some of the ones that will work.† Remember, we are pushing the envelope here and the space is extremely tight.† The subs we used are the Rockford R2 and they work very well.† We will not take returns on this box if 'your' sub doesn't fit.† This is a specialty application, please choose a sub from the list or find one that does fit.† 8" subs will be more forgiving, so go that route if you want to play it safe.

10" shallow subs that fit:
Rockford P3 Shallow
Rockford R2 Shallow
JL Audio 10TW3
Pioneers: N/R

A note about†Pioneers: Pioneers†traditionally have all different cutiout sizes and frame sizes on their shallow subs.† In other words their different models are all over the place in this regard.† If you plan to use pioneers make sure you select a model with a cutout†that will fit our standard hole size of (9-1/8") but also fit's the depth requirement of the box.††
†This is why we really do not recommend pioneers.† The others on the list are far better and will fit the hole requirement.† Please be aware that if we have to modify our design for a larger hole size, that this will require building the box from scratch and therefore a customization fee will be applied.†

2021 GMC Canyon. Excellent box - well built with attention to detail. Built on demand when ordered- not a mass produced prefabricated box for a one size fits all vehicles. Highly recommend if you drive a GMC Canyon or Chevy Colorado. The amp shelf was an added bonus as it prevents drilling holes into vehicle to mount the amp behind the rear seats. Very creative, clean, well constructed box!..

Built perfectly, fits like a glove. Kenwood excelon kfc-1000 shallow mount sub fits like a glove and sounds fantastic @4ohms with kenwood 500 watt monoblock...

Very happy with this box, however it does not fit a JL 10tw3 as described without enlarging the hole. That sub requires a 9.65" cutout. I was initially very disappointed but I was able to make it fit using an oscillating tool. The results are well worth the work. Sounds great. Shipped in about 3 weeks to Manitoba, right to my front door. ​ Highly recommended...

I bought this box not to long ago, I put one 10 inch Rockford fosgate p3 shallow subwoofer inside, with a 500 watt Memphis monoblock, and I could not be more happy with the results. With the little room under the seat, the subwoofer hits harder than some 12's I've heard. This is an outstanding product and I would definitely recommend it for anyone with a 2015 or 2016 Chevy Colorado...

Excellent box, very well built and quick delivery. I used a Rockford Fosgate Shallow Mount model P3SD4-10. The sound of this sub in this box is phenomenal and hits hard. The extra spot to place the amp with access holes for cables is a nice touch and made for a clean install. Well done guys!..

I recently installed this enclosure in my 2017 GMC Canyon Denali. The enclosure blends itself right in to the interior of the truck, basically unnoticeable, which is what I wanted. It houses a Rockford Fosgate P3S 10Ē 2ohm DVC Shallow Subwoofer that Iím running in series with an Alpine MRP-M500 amplifier. Sound is incredible, it hits very hard, the bass is very punchy and accurate. Iím very glad that I went this route instead of a Kicker vss or similar...
