Enclosure for 18 in sub

[vondocha 10+ year member]

How much airspace would I have with these dimensions 14.5" x 30" x 32.25" after putting say a HDC 18" sub in it? Enough airspace? Or should I go with a 15 in? Any recommendations? Thanks.

Not gonna be enough for an 18 7.6 outer before port and displacement.

Really darn. I was hoping to somehow fit an 18 in there :/ Well that's that! I'm thinking of getting the HDC15 with the either the 1200 or the 2200 but not sure which yet. I don't want to get the 1200 then want to upgrade and have to buy another amp but idk. Decisions, decisions...

Hdc3 will be much better with the 2200.

Hdc3 will be much better with the 2200.

I'm sure it is but for electrical all I have is the Big 3, yellow top, and all 0 gauge wiring. I don't think my little corolla can handle much past 1500 rms don't you think? hehe

Throw a nice rear battery in and you will be okay.

I ran my 2 hdc3s on an AQ3500.

If you want to stay with 1200rms I would look into another subwoofer IMO.

Any ideas in mind as for which subs? And why another sub?
