well all my pics were from a 2003+ silverado but i beleive the way the back seat is constructed is the same if not very simular throughout most of the different body styles.
We just got done raising the seat in a '05 SS 1 inch. It was fairly easy. We used 1" blocks.
We also did a glass bottom enclosure that netted us with 3.66cu^ft of internal displacement.
And what to do in 3.66cu^ft?
8 RE8's of course, ported tuned to 32. //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif
Power them with a Zapco 1100.1Z and let them fly.
It's deffinatly our "loudest" system we've done under the seat of a chevy ext cab. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
