Just finished my first box, used one of Moe Lester's plans for a 2 cube tuned @ 35hz. I'm using a 12" Memphis Power Reference sub with 270 watts of power from my amp. I think everything turned out pretty good considering it was my first system I did on my own. Total I got about $600 bucks in it which includes 4 3.5" MB Quarts, Alpine Type R 6x9"s for my doors and a 12" Memphis sub and all the other smaller stuff, aka wiring, box material and so on. The doors and sub are running off a 4 channel U.S. amps I/S 4085. Only thing I gotta do now is either carpet or vinyl the box. Here's the box and sub.
So how did I do? It gets freaking loud I know that much, at least loud enough for my taste. lol
