So I've pretty much decided on what sub I am going with so now I am trying to come up with box designs. I have a Lexus IS300 and there is a "ski pass" from the trunk to the cabin. I have seen a few builds with the sub firing into the cabin through this pass like this...

I was considering this configuration but have a feeling that a rear fire set-up would sound better. Opinions? Obviously I won't be using that sub. How about having the ports firing into the cabin? Or both firing rearward?

Going for a solid mix of SPL and SQ.

I think using that skipass would sound good if you had the port of a bandpass coming through there. Or you could do a slot port box and have the port come through there and the subs face ths sides. How many subs do you have...

+1 on the bandpass into the skiport, if can build to seal nicely into the ski port, that should bump pretty well.

I was going to do a single 10" or 12" set-up.

What 10" or 12", and what power?

DD 2510 is the leading candidate right now. Cadence a7hc (1000w@1ohm?). I want a mix of SPL and SQ.

I would go with a 4th order with the port through the ski hole personally.

Ok, a 4th order is a BP, right? I tried to use some box calculators to see about what size box I would need but I can't find all of the necessary specs. DD's site only has the "Q's" and Vas. I am assuming it'll be ~ 1.5cf, but from what I understand, just getting it "close" isn't going to get it done with a BP box.
