2001-2006 Chevy Silverado Crew Cab Sub Box NonHD Ported Jumbo

­The 2001-2006 Chevy Silverado Crew Cab 1500 trucks are pretty limited on space for a big sound system, until now! This is a design that we’ve been doing locally for a little bit now, and we decided we needed to release this to the world. Our regular enclosure for these trucks for behind the seat is 1.5cuft of airspace, not a whole lot and not enough for an over the top sound system. This one is 3.25cuft, plenty of room for some big bass!

This enclosure is 3.25cuft total airspace and has a mounting depth of 6 3/4″ based off of a 6″ magnet diameter. For larger woofers, we can use our metal backplates to add an additional 3/4″ of mounting depth for 7.5″ of room for some larger woofers.

What we’re doing to get this space is using our seat adapters to move the seat forward 2.5″. Even with moving the seat forward, this still allows full function seat functions with laying it flat and flipping the seat back forward, but now getting some over the top bass you’re looking for.


For installation, the normal behind the seat preparation is necessary with the removal of the studs from the spare tools and jack and with trimming the vents back. Then to install our seat kit, you unbolt the 8 factory nuts holding the seat in place, lift the seat up, slide our kit in place, use the stock nuts to hold the bracket it place on the factory studs, and use our nuts to hold the seat down on our new studs. Now tighten everything down and you’re good to go.

This is a ported subwoofer enclosure. Ported subwoofer enclosures 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 typically double the bass of a sealed box with the same subs and power. 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 designs will be what you want.

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 subwoofer’s 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 enclosure as needed. We tend to tune our boxes low, 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.
