thought i would share a few pics. the top is all fiberglass with sub rings. made it on top of my original box. my new subs required 2 ft each. i made it to fit side panels in the back perfectly and as u can see the filler panel on the back of box also. almost done

 

Nice enclosure!
So what the port tuned too, how many cubic feet per sub.?

 

i got 2 foot per sub. the subs required a box tune of 37hz, they require 2 foot a sub also. it sounds really good now. get my new amp tomorrow with more power for them
