Well I need a new project to mess around with and practice building subs. Its an 8" sub, but It will use a 3" coil and 8" spider. I ordered a Sundown SA-8 cone to play with in the basket here. I am thinking I will use a RE SE or SX motor. Sorry it looks kinda bad, but my image capture wouldnt work so I just took a picture of it on sketchup haha.
I don't know if this would be to big I have a mtx rfl motor it 8.5 inches wide Also you can try a dd 3500 you could also try a jl12w7
