You called me a nood in one thread.But you dont even know how to tune aeros or 2 secure them. Quit being cheap and buy the flares for like $3 a pice and it will be alot easier.

Why not use 6" or 8" pvc? IMO thats too many 4" ports for that size box.

i'd do 2 10" , they sell big tubes in home depot, cut them and fiberglass it to the box, or do 1 12" roudn port... or 3 8", 6" are too small IMO...........................
