My buddy has a trailblazer and got laid off and a few kids n wife and ya not a lot of money left over for audio... He's been bassless for a few months.
Equip left over from previous build:
2 sundown zv4 18s
1 sketchy ct 2200 at 2ohm because it shuts off at half ohm
270 jp alt or whatever company that is
1 Duracell 3100batt
He got all the wood from work for free I do believe. It was a pallet box from shipping that he took apart and brought home. It's 1" thick, not sure what kind of wood? Birch? We built a cpillar wall.... The wall is 15 cubes after displacement with 162" of port tuned to about 33hz.. It will be gettin double baffle when he gets the wood.
