Dual Sub Box Under Rear Seat for 2001-2006 Silverado Crew Cab HD

This Silverado crew cab sub box goes under the rear seat of 2001-2006 Chevy Silverado HD and GMC Sierra HD crew cab trucks, with the subs firing down toward the floor. It holds two 8" or two 10" subwoofers, or a single 12", and is made only for the 2500 and 3500 series crew cabs.

Fits

• 2001-2006 Chevy Silverado HD series crew cab (2500 and 3500)
• 2001-2006 GMC Sierra HD series crew cab (2500 and 3500)
• Also fits the 2007 Classic body GMC/Chevrolet Silverado only; the new body style 2007 truck takes a different box
• Rear seat must be a full bench or a 60/40 split; it does not work with bucket seats
• The truck must have the brace on the passenger side under the rear seat, or the box will not fit
• Does not fit the 1500 series (1/2 ton) crew cab; Xtreme Enclosures makes a separate behind-the-seat version for the 1500 and HD crew cabs
• Does not fit the Silverado extended cab

Specs

Install notes

• The bar under the rear seat on the passenger side has to be removed before the box goes in.
• Install instructions for this step are available on request.

Choosing your subs

Check that your subs need no more than 6 1/4" of mounting depth, that the magnet is under 6", and compare the cutout with the standard sizes above. If you do not know your sub's cutout diameter, type the sub model in the "What Sub Model are you using?" box when ordering so the box is cut to match. Shop 8" subwoofers, 10" subwoofers or 12" subwoofers.
