CUSTOM SUB BOX BUILD | 05 GMC Sierra Crew Cab with 2 Skar VD-8 Subs

In this video I am building a custom subwoofer box for my 2005 GMC Sierra 1500 Crew Cab. I will be installing two Skar Audio VD-8 D4 8" Shallow Mount subwoofers behind my backseat, powered by the Skar Audio RP-800.1D 800 watt monoblock amp. I will leave a link to the subs, amp, and supplies for the box below. This custom subwoofer box should fit any 1999-2006 GMC Sierra 1500 Crew Cab as well as the 1999-2006 Chevy Silverado 1500 Crew Cab. This will also work for the 2007 CLASSIC Chevy's & GMC's as well.
