How to wire up TWO Dual Voice coil sub?
Ok I need help with wiring up TWO (2x) Alpine 10" Dual Voice coil sub (4 ohms) to this Infinity Kappa Amp
http://manuals.harman.com/INF/CAR/Owner's Manual/KAPPA202a-OM.pdf

The equipment-
2x 10" Alpine ZR10 sub
-dual voice coil
-4ohms
-Power handling 1000 watts peak
-Power handling 300 watts RMS

Infinity Kappa 202a amp
-2 channel amp
-2ohms operational at 300RMS

-4 ohms 2x 200watts
-2 ohms 2x 300watts

It's been a while since I have wired subs. Especially two dual voice coils.
What would be the best way to hookup this combo?
Thanx

This way would be 2 ohms to get 300x2 correct?

That can't be right it's in stereo.

OK this is why I am confused. By wiring them series/parallel won't I get 4 ohms load?
So what would the amp be seeing the load as? (Hooked up in mono) 4ohms or 2 ohms?

This has to be the way.
I went back and reread the spec on the amp.
power out put is
-4 ohms = 2x 200watts
-2 ohms = 2x 300watts
(here is the parts I missed)
-power out put bridge-4 ohms = 600watts

Since I am NOT bridging the amp, I am going to connect the speaker in parallel and each speaker going to separate channel. Running the amp in 2 channel mode seeing a 2 ohms load per channel producing 2 x300 watts in 2 channel mode since the amp can do this.

So am I correct?

I believe this diagram to be correct for your amplifier

Note this section in your owner's manual:

"Kappa 202a Amplifier Features..."

The Kappa 202a is a 2-channel power amplifier that offers stereo, bridged-mono, or tri-mode operation, and is rated at 200 watts (rms) per channel into a 4ohm load. In a bridged-mono configuration, it can deliver up to 600 watts (rms) for the same load.

Sure you ~could~ run the subs in stereo.. but that would be of no benefit as the sub freqencies are not "stereo" to the ear (that is a whole other discussion).

Running the amplifier in bridged-mono load.. at a 4-ohm load will give you the power you need, and allow the equipment to run cooler with less strain.

Good research. Enjoy.
