In 1997 I had an '84 4Runner with 9 JL 12W6s on 3 Orion HCCA 225s. Split the removable top about 12 times, split the permanent top twice, warped the rear quarterpanels, shattered front and rear glass....
The 3 boxes were JL-spec, dealer-built. The first set of 3 I had did 149.7 on an Art series 600 PPI amp, at 4 ohm mono. It was in the bed of a mazda, cut thru the cab. I got those 3 in the box for $400. The second set of 3 in the SAME EXACT box were $300 and the final set of 3 was $150, and the box costed me $300.
