2019-up GMC Sierra Crew Cab Sub Box Sealed


2019-up GMC Sierra Crew Cab Sub Box Sealed

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 sealed subwoofer box. 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. For customers who want louder deeper bass with the lower bass more pronounced, a ported box is what you want. Because of the ported design, the bass will not be as tight and punchy, but there is double the bass of a sealed box with the same subs. If big bass is what you want then our ported box will be what you want.

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.
