my 12w6v2 was amazing in my G... and honestly I was scheming on making a box i could easily take out for track days... the 12'' needs about 1.5 cubic feet. The spare well is about a little less than a foot deep. Maybe make a circular sealed box
So lets say 1 ft depth with so then surface area of the box would need to be 1.5 ft squared.... so lets see...
pi*r*r = 1.5
r = sqrt(1.5/3.14)
r = .7'
so... you would need a box thats about 1.7' radius x 1' depth hmm ill do some measuring when i get home n let you guys know
