Did some SPL testing in the Jeep with the 18" version of the "Magic Box" this morning -- it is slightly less efficient than the 15" version but still does well. I am pleased with the results -- will continue to push for more score as time permits :

Holy crap. 6 times as much power, but it sure opened up lol. I see Gary throwing 2 of these in to test them out just for the hell of it.

Tweaked it a little more -- this is going to be it without getting a "real" power setup in here. Seeing ~11.1v at the amp terminals so not going to get more juice as it sits.

May drop in some more batteries and bigger amps some time this week to see where the SA-18 tops out smile.png

** Score on the right is legal score with more power; seems like it may be tapped out now... but will try a little more later.

** This is what we dropped in for testing; basically battery limited now.

Can you meter it on 600-1000 rms? It would be more realistic power range that most people would run in a daily setup for non competitors.
