Well I finally decided to get rid of my wall with the two 18's. I went home from school this past weekend and tore it all out, and that expanding foam was not easy to get rid of. Figured I'd start to build the new box and I got that done now just waiting for my third sub to get here (tomorrow) and this upcoming weekend will hopefully get it all installed. System consist of two sets of rockford fosgate punch 6.5" components, mb quart 4 channel, three 18" Fi fully loaded BL subwoofers matched with three AQ 1200D's.
What a mess...
Boards cut and glued with some cement for pressure
Three 8" sonotubes coated with fiberglass resin
