12" Sub Coupled With A 15" a Bad or Good Idea?
12" Sub Coupled With A 15" a Bad or Good Idea? If I run a 15 in its own separate enclosure & a 12 in its separate enclosure as well. Will it sound good? Or is there a big difference in bass? The only reason I want to do this is because the only cubic space available is for a 12....

Seen it done befor, but i wouldnt do it. Frequency responce on the 12 and 15 are going to be diferant.
Unless you cross them over where each sub is only used in its optimal range, and those ranges dont overlap.
Well there is alot to it, why not just 2 -12" ?
Or 2 -15"

You will be fine if you run 2 different amps, or at least 2 different crossovers, you will need the 15 to run your low-low stuff, and your 12 to run higher stuff. Have your 15 run line 20-60, and i would really run a 10 and run 60-110. You will also want to make sure you a 6.5 that will run like 80-600 and the a very nice set for mids and highs.

Well Not too sure what else you are running but, if you're looking for some more bass, I'd recommend going with 2 12's. I'm not a big fan of 15's myself but that's just me. If you want to keep the 15, then look at running some good seperates for your other speakers (if you haven't already done so). That should give you some nice, medium-ranged bass throughout your car. Also remember that the type of bass that you will get from your 15 will depend largely on what type of box you run. Sealed, ported, and band-pass enclosures all give different types of sound. I'm figuring that, since you are only using one 15, that it's a sealed enclosure?
If it was me, I'd sell the 15..buy 2 12's and get an enclosure(s) that would give me a little more solid bass. But that's just me.

Maybe you want to check your amplifier set-up, I have a single 10" and i can shake the outside mirrors with it, If you don't have enough base with a 15"...I don't think another will help. I don't even think you would hear it.

how is the sub mounted? if its NOT aimed at the glass then you can almost double the sound just by aiming it at the glass. also, what amp are you running it with? chances are if you get lots of clean power, itll help. finally, what kinda box? a ported box will yeild you great sound Q and lots of output, but it need to be built exactly to spec.
how about some more info and some pics.
theres not a lot of benefit to running a 15 and a 12. for SQ reasons, youd want to run a 15 and maybe 2 8s, or a 15 and a 10, and for SPL, youd run as many subs as possible or build the setup right to maximize the SPL.
trust me, for $330, that box isnt the best for optimal SPL. it needs to be
1) aimed at the glass (either sub or port)
2) ported and built to spec
3) built from at least 1" MDF and braced (you want minimal flexing)
4) powered correctly (a 1000 watt RMS sub can take 1200+ clean watts RMS *only an example)

and you asked about an isobaric box, thats not done too often these days. i dont think modern subs work too well with that configuration. That was more popular back when subs required much larger boxes.
