Custom Enclosure Build - RD Audio - Chevrolet Avalanche (4 18's - 21 Cubic Feet)

This was done for a customer that drove from Louisiana to pick it up. It will be housing 4 18" RD Audio SHW subs. This is built with a 4th Order Bandpass design. It was built for the bed of the Avalanche with a blow through. It is lined in truck liner material and also has LED lighting inside of it. It has a removable cover for taking in/out the subs. The customer didn't have the amps hooked up and was missing 1 sub, so we couldn't get final photos once in the truck.
