what model aq subs are you plannin to get?

Just recently got a new ride, an '08 Vibe so I got a hatchback design to work with. I'm not sure how many cubic feet I'm dealing with, but I'm thinking there's about 7 or so back there. Anyway, I'm definitely going with some Audioque HDC3 subs, I'm just wondering what setup I should go with? A couple of 10's? or a couple of 12's? Or just 1 15? Or maybe even 3 10's? I'm thinking 3 10's would slam in a hatchback, but I have heard before that subs in uneven numbers isn't a smart choice? Anyone got any advice?

thanks i was readin to fast lol

op, get the 10's and 1500 or 2000 wrms to each //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

just get 3 sdc 10's and 1 2200 d.Ya you may wire it a tad under rated ohm load but you wont be crankin it full tilt all the time.I have downsized to 1 sdc 10 on 300 watts and it is surprisingly loud.With out upgrading elec. you could do the 3 sdc's and 1 amp and be plenty loud in a hatchback.Just my 2 cents,Im always on a tight budget so i tend to lean towards the most spl for the money...good luck on you decision.

Yes I certainly plan to upgrade the elctrical system first, trying to sell the old system to put some extra cash in my wallet first though so I can do it.

I appreciate the input everyone, I think I'm gonna do the 3 10's. I got a guy who builds custom boxes, so I wont have a problem making the box for 3 of them and hopefully I can get started on this project sometime soon

And yes, running 1/0 for all wiring and such. Quick side question, as I've never ran anything bigger then 4 gauge. What is a good brand to go with for 1/0 wire?

i thought

thats where you went wrong

Yes subs in uneven numbers is very bad, Definatley dont have just one sub cause thats uneven and its baddddd

are you serious?//content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

I'm assuming he's a jackass, unfortunately //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Okay, keypoints.

Three 10's vs two 12's - roughly same amount of airspace require for standard ported applications

Cone area is very close - three 10's have a cone area of 235.5 whereas two 12" woofers would have 226.08.

Two 12's vs three 10's - I'd go two 12's myself. With three tens you're not gaining any significant cone area and the three woofers are going to require more power than the two, generally speaking.

Blah blah

Ah, I see. Well, considering that, I may even consider 3 12's.

So then wait, another thing, the fact that there is 3 motors working and therefore more motor strength to work with, wouldn't that essentially mean more SPL? (I'm aware other factors go into it but isn't that the gist of it, more motors means more power?)

It all depends if they are efficient motors. efficiency plays a big roll in sound.

Depends on efficiency really vs the power you use.

Take three HDC310's vs two HDC312's.

Three 10's on 5k the two 12's on 5k. Results, depending on box relativity, should be very close. However, you can probably throw more power to the 10's now without hurting them whereas the two 12's are going to attempt to die shortly thereafeter.

More similar woofers, you run more power, that's the easiest way to look at it. Same power, should have very very similar results.

I said two 12's simply because it's less power to push the woofers to their potential and quite frankly it's easier to work with, generally.

x2 on the two HDC312's off a 3500d.

Of course, if you can fit three 12's that'd be even better, but two hdc3 12's off 1750 each should be plenty loud.
