2019-up GMC Sierra Crew Cab Sub Box Ported


2019-up GMC Sierra Crew Cab Sub Box Ported

The brand new 2019 GMC Sierra is a great looking truck and is a God send for guys who want big bass in their trucks! This box is for the new 19-up GMC Sierra Crew Cabs. The 2019 Sierras have a much flatter floor under the back seat which will make fitting a box in this truck a bit easier than some of the past years. On top of that, it’s about 2 1/2″ taller under there! There is a ton more space under that back seat. With 2.21cuft of airspace total there is enough room to do a couple of 10s or 12″ subs in this box. Mounting depth is pretty good at 6″ for 10s and 5.25″ for 12s and that is based off of a 6″ magnet, so it is possible to put some real subs under there. The bump options are going to be the best bet to get a decent mounting depth in this. We have 2″ legs on this box, so we are getting good mounting depth and also plenty of clearance for the subs to not be hitting the floor.

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 is our ported design. This design is for maximum airspace and the airspace of the box can be reduced if desired. Our ported boxes are designed according to your subwoofers specifications. No two boxes will really be alike. At checkout, there is a Comment box, please give us the model number of your subs and we will build the box as needed. We tend to tune our boxes deep, around 34-37hz. If you have any specific requests please feel free to let us know.

This box is made out of 3/4″ MDF and is fully carpeted in matching carpet. The nickel 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.
