Since I'm still pretty new to the sub/speaker world, I figured i'd ask everyone here.

Heres my setup:
2 15" Lanzar Vibe VW15D
2.5' High Temperature Dual Voice Coil
Magnet Weight: 120 OZ
1000 Watts RMS
2000 Watts Max Power Handling
Impedance: 4 Ohm
SPL:90dB
Frequency Response: 40Hz-3000 Hz
1 12" Lanzar Max
1000 Watts Peak Power
4 Ohms Nom. Impedance
SPL: 91.9 dB
Kole Audio Q2-1920 Amp

Both 15"s are in one sealed dual-chambered enclosure, and the 12" is in its own seperate sealed enclosure.

So, I need suggestions on wiring all of this. What way can i get the most power out of this system with the least amount of damage done?

Also, since the 15"s are dual voice coil, how exactly do I go about hooking those up? I was thinking about running each of the 15"s in a series so each is 8 ohms, plus the 4 ohms from the 12", however like I said: im new to this world, lol.


EDIT: well, I think I figured this all out. I have each 15" DVC wired up in a series so each has 8 ohms, then have those two 15's wired together in a parallel circuit into one channel, so that has 4 ohms.

The I have the 12" on the other channel, so that's 4 ohms as well.


Think this is the best setup for 3 subs and 2 channels?

 

you really want it right, here it is - but you may not like it.

Take the 12 out all together, it will not help like you want it to. its only going to rob power and air from the 15s.

wire each of the DVCs in parellel (pos to pos, neg to neg) and one on each channel. that amp will put 440 rms to each sub and you will se much more out of those 2 as now they a sharing 330 rms together.

give it a try and see how it works.

 

Tried wiring it up how you suggested, and they definitely seem louder. The vibrations seem less though, but that may be better for my car in the long run :P

 

heres the thing, the sound volume of bass is created by air movement and compression, and the freq waves paths. the extra 12 would screw you because of the freq paths and the misaligned/odd ball air movement. everything might not shake as much - but i do bet the overall bass sound is louder. If you really want to take it up a notch - use a Power Acoustic 3000.1D amp. my friend ran 2 of those Vibe subs with that amp in a 2002 4dr blazer and hit a 151 bd at comp. I was inpressed to be honest and there was no fancy box he used - just a dual chamber sealed in the cargo area facing straight back. So do know there is much hope still.

 

I made a stupid rookie mistake

Since I had rewired them yesterday to just the 2 15"s, it didnt seem quite as loud or shakey as with the previous setup..and today I actually decided to look at the subs and see why. Only 1 15" was hitting - I forgot to plug the positive back into the other one

Daaamn they hit now. It is definitely noticably louder with just the 2 15"s than how I had it before.
