1988-1998 GMC Sierra Extended Cab Sub Box Dual Small Ported
The 1988-1998 GMC Sierra Extended Cab trucks gave birth to the under seat down fire box. This body style truck was the start of the sport truck movement and as around when car audio started it’s boom. The space under this rear seat is limited but there are ways to get plenty of sound out from under there. The tool box and jack storage is in the way, but once it is removed there is plenty of room to squeeze a couple of 10s under there. The box sticks out from the front of the seat a little bit but that is the only way to get anything with a decent surface area under there. The box is full width with 1.2cuft of airspace which is spot on for a couple of 10s with up to 5 3/8” of mounting depth.
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 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.
