i recently got rid of my 3 Comp VR 12's and 3 Kicker Impulse amps that i had in my van. i was metering at about 149-151 dB. i'm currently looking to get 2 or 3 L7s eventually. what are you running yours with and what size/port tuning on the box? a lot of people think SPL is dumb and "all that bass sounds like shit/isn't needed" but its a hobby just like anything else that some people are into and some people aren't. and if you set it up right, it can sound pretty good.
