I'd still place my vote for the RL-p's The BTL isn't going to sound very good daily.
It might make some people happy, but the ones I've installed were lacking in the SQ department.
If you want numbers, I hit a 148.3 with my two 12's Using the Termlab mic. The score was made full legal (mic on the dash, sealed up.)
BTW I hit a 151x mic in the kick, drivers door open!
I made the score using Hifonics Goliath I borrowed. The subs started smelling after about three long burps. But they took the abuse very well!
