Well first off thanks rbgnwa45 for the info on cone area. That is good to know. You asked earlier what car it was in and it's a genesis coupe. Dukk says that I don't have to cubes for what I want. I can get a 3.5 cube box in that trunk max. The kickers would need 1.75 each so 3.5 for both at a min volume for ported and that is what I can fit. Mind you If I take into consideration of the sub and port displacement it would be a bit smaller. Would this not work. At first I was leaning towards 3 alpine 10's and now I think I might go 2 12" Kickers. Man that would pound hard in that little car. Still a tough desision. I have 2 10" re audios in there now and they hit hard but I am a bass fiend and want more. I want to make a 3.5 cube box and load that sucker with something that will hit me in the chest hard. Porting up through the rear deck is my only option as there won't be enough room on the front of the box to port it forward. Check out my vid. It might help you guys to help me decide. Oh and I want spl more than sq but don't want to tune as high as my cars resonant frequency. Mabye 35-40 hz or so.

3.5 cube box, I would go to one sub like a monster Digital Designs and give it the power it needs. The "small box" is the marginal amount of airspace for "passable" bass response and not "ideal" or "extended" bass response. If you are after ideal response or are trying to rip the bra off of your passenger, you are looking at the equation wrong. Look at the space you have available, then choose a sub(s) for that application and finally the amp to power it.

the amp I will be using is the one in the vid ( hifonics bxi2006d ) and yes I do want to rip of her bra but not with bass LOL. The bass is foreplay. So what are you saying? Go with a big 18 or what? I have an re audio sx 18 sitting in front of me but the specs require a box that is at least 5 cubes. You are right I have to work with the box size that I can fit in there which is 3.5 cubes. So I thought 2 12's or 3 10's. Even 1 15 would be to much air space would it not. Mabye put 1 18 in sealed box. I don't know.

How about 3 10 inch kicker l5's? Now that might just do the trick.

I think everyone that is on the kicker bandwagon is forgetting to tell this nice gentleman that kicker coils are about as fragile as a 90 year old womans bones. Go with the R's

I'm in with the comments about "More to go wrong with 3 10's" ...
Plus I think the 2 12's you've chosen better match what you're going to throw at them ...

And fragile coils? Never heard that one before ...
I pound on Kicker daily ... nothing has happened. Guess I'm lucky

Ok, I think I have made my desision. 3 10" Kicker L5's. The last guy said though that kicker coils aren't up to snuff. I hope he is wrong cause I believe this will be my setup as I can get these subs for 500 shipped. Will run off about 1700 rms but will also be at 1.33 ohms which will probably bring down the power a little to say 1500 or so. So the kickers are 450 each x 3 would be 1350 so pretty decent match up there I think. The only thing now is that I sat down and figured that the box I will biuld will be 3.25 cubes after magnet displacement. The kickers call for 1.25 per min so that is 3.75. Do you think I could get away with this size box if its ported and what frequency to port to. If not than I will make a 3.25 sealed and go with that. And one more thing. Would I lose a bit of db in that sealed box compared to ported? Thanks guys for all your input. I can't wait to start building this thing. woooooooohoooooo.

Moley

One more thing. What would you chose? 2 12" kicker l7 ported or 3 10" kicker l5 sealed?

I think other users will weigh in on the type of port you might need for 3 subs, but it depends on what you're after ...
3 10's, you could definitely do a crazy sealed application (both showy and functional) but then again, if it's the output you're after as well, then maybe ported is your answer.

I'm not the expert on this one ...

(Oh and by the way, I have 2 12" L5's and I broke the box, before I broke the coils ... so like I said, that isn't something I've EVER experienced)
