Correct me if I'm wrong but....

Wiring 3 D4 subs I can get a 2.67 ohm load and a 6ohm load. So I can only run a 2 ohm load amp or a 4 ohm load amp? No chance for a 1 ohm load right? But going off 12volt, I can??

Option 1 (series/parallel) = 2.67 ohm load

Voice coils wired in series, speakers wired in parallel

Recommended Amplifier: Stable at 2 or 1 ohm mono

Option 2 (parallel/series) = 6 ohm load

Voice coils wired in parallel, speakers wired in series

Recommended Amplifier: Stable at 4, 2, or 1 ohm mono

I'm not sure what your asking here. You've been around long enough to know how to figure impedance. If your load is 2.67 then of course you can run a 1 ohm stable amp, your just not going to get full power out of it.

 
Correction D4 not D2. Bubba I get impedance but I've never run 3 subs, always been 1 or 2 subs. Just not 100% sure if I will get the best power at 2ohm or 1ohm amp for a 2.67ohm impedance. Figure 2ohm, but the amp I'm looking at is 1200rms @1

 
An amp will only run at the ohm load presented to it by the speakers. Thus, if your drivers wire down to 2.67, even an amp that is stable @ 1 ohm, will be running @ 2.67 ohm, and producing as much power as it does @ 2.67. The only thing separating a 1 ohm and 2 ohm stable amplifier is how they are rated, and what is a safe impedance to run them at.

For example: An AQ 1200d gives 1200rms @ 1 ohm, but would be closer to 600 @ 2.67 ohms. A Kicker ZX500.1 is not 1 ohm stable, but will produce 500rms @ 2 ohms, which is its main rating.

Impedance is a variable that affects power. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

 
Well just remember, if it's rated for 1200w @ 1 ohm it's going to step down for each increase in impedance. So it's likely to be 600w @ 2 ohm, etc. I would suggest looking for an amp that does MORE than what you need at 2 ohm. So if your looking for 1200w then find an amp that does 1500 at 2 ohm.

Not a bad idea. Kicker and Alpine both make many amps that are primarily rated @ 2 ohms. That may make it easier on you.
