Gmc Sierra 2 DC lvl 4 18" xl's

Looks louder than 145.
I am doing that in a trunked car on two 10's right now. 2 10" Pioneer Premier w-250spl ones on 1700rms.

Mine don't flex like yours, but I have a good amount of fatmat/SS Damp in my ride.

Nice job!

Yeah The only reason I hit a 145 is that one sub got loose and there was a gap between the box and sub:eek: and the subsonic was at 45 so It wouldnt let me play at lower frequency which isnt good because Im tuned at 33Hz. Now that I fix the sub and Will dynamat the roof I hope to get around 149 on the TL
