I already have one rl-i8 soundsplinter but i worried that I won't get enough out of it (not in car yet) so ive been lookin at porting it I can't go any bigger then 1 cube after port. it will get 400watts. I would just get one more and do two sealed but I can't afford another one. I have never built a ported box before, what size chamber and port do I use? can I just build one like this guy? this would fit in where I want it. at 400watts would this get plenty loud? want to hit at least 135db.

if you're unsure on how to build a ported box i sure wouldn't start out with a fiberglass ported enclosure.

building small low tuned boxes can be a task too, not worth the effort IMO. by the time you're finished the box is nearly so big you could have gone with a 12" sealed.

My 12" Rlp sealed is in a much smaller box than my Rli8 ported. It isn't even 2/3's the size. Building a ported box for a small box driver like the RLi8 isn't trivial and doing one out of glass is near impossible unless you have a lot of experience doing it.

This will give you an idea....

I really should have slanted the corners as well, but half the purpose of me putting this box together was to show others what a .65cuft box tuned low looks like.
