What enclosure is best for RD Alphas/Heavyweights 12" & 15"

Does anyone know the recommended enclosures for the Alpha v.2 12" & 15", and the Heavyweight v.2 (daily) 12" & 15" subs?

To do what?

As far as alphas & heavyweights, what size box is recommended for each, and is that vented or sealed? my trunk has 15.6 cubic feet of space, total. the height behind the seat is 17", width is 37", & it is 26" deep from the top of the backseat to the base of the back windshield or opening of the trunk, & 31" deep from the bottom of the backseat to the trunk opening, which could make for a good dual 15" from behind the seat. Or would you do something a little more powerful or creative with those dimensions?

To fit in 8 cubic feet of space, and thats about the maximum size box i'd be willing to put in, but I only have 17.5" height to work with. i'd like to know which sub combo would get the most out of a D9? Which series sub, RD ALPHA OR HEAVYWEIGHT, & in what ohm voice coils, and in what size box, and whether it should be Vented or sealed is the best for that size of an area. With a frequency response, or tuned in the mid 30's, also, I guess?
In other words, does anybody know the recommended enlosure for Alphas or Heavyweights, size 12" or 15". Thanks in advance. I'm kind of lost here!

The 2 I did in the impala I did was less than 8. If you can fit a 17x37x whatever box then id def put 2 of either 15 you mentioned in a big fwd fire box. That leaves a decent bit for port. Not a ton. But def enough. Either woofer will handle a d9 no problem.

The guys here doing the install said that one of the guys at RD Audio, who he gets recommendations & specs from, when doing installs that may be complicated(they mainly intall Sonance & Classics for customers, because most wont pay for elites,alphas, & hw's), and they said 3 Elite 12's would put the D9 down to 1 ohm, and would be ideal.what do yall think?

Where would the port go in a 37 wide box and 3 12s?

Good question, can they fire to the rear, & have the ports firing in the cabin or what?

Nope. The box will be in the way.

Ok, so idk, this is not my expertise, as you can clearly see. I just dont want spend the money, & end up with shotty results. Any thoughts to make it work, & get the most bang for the buck.

Lol. Pretty sure that info has been offered.

2 dual 2 ohm Alfa 15's subs forward subs forward port. 5 cubes after displacement. =bang for buck!

I like that! I keep tellin them 2 12" or 2 15", he wont hear of it. Says they need 5 cubes each. Told em I talked to you, he says that puttin em in that small of a box is more for comp, or spl. Not street beat, or sound quality. Bout to just tell em what I want, & just do it!

I'm about an hour away from you if you want to head up I'll look at what you have going on and make recommendations. Then I can either build out your car or they can, but at least when you leave you'll be educated enough to make a decision on what to do.

That sounds like a great idea, Villa Rica, right? Dont know when, I'll be working late every day this week, and on vacation in Florida from Saturday, 26th until follwing Saturday. I wont be getting the subs til probably the week I get back, so I'll ride your way sometime that week after the 4th. If that's good for you?

Yeah, I've had many opinions presented, all with different sized Alphas or HW's. I was trying to figure out which sub is best suited for the space available, and why? I doubt you could build a 2 cube box and have the same results with both speakers, correct? So, why the sarcasm? Chris helped a lot today over the phone, & I missed his call earlier, but I think he understood why I was still unsure. Both of you are on the same page with 2- 15" facing forward, & he believes Alphas would be the best bet with 2.5 cubes for each. I really do appreciate everyones help with this, but I want whatever its gonna take for Metallica, pre-90's of course, double-bass to sound great, and when in the mood, Lil' Jon will sound great as well. Thats why I was looking for exact info for both subs, or at least the best-case scenarios for the D9, & available space. Not trying to waste anybodys time, or beat a dead horse. Thanks for the help.

The sarcasm was there for exactly the reason you know it was there. You asked the same questions after they were answered. Anyway.. I surely would put 2 15s in 5cubes for daily. But chris already helped ya..

Actually, Alan, nobody had said, with either speaker, regardless of size, what the recommended enclosure should be. But yor right, Chris got it and thanks for your help. It's all good. Have a happy 4th weekend.
