You guys are fvcking stupid. It's hard to get loud in a Tahoe. This is a ground pound build not spl. I'm tuned low and can play down into the teens and peak at 38hz... Tahoes have lots of air space. If I had a bpillar wall I could be at a 57db no problem. I did a 53 on 1 8k. That's a decent score... This site is a joke filled with dbags
