So I have two Dual 2ohm subs to wire up to my Kenwood KAC-9106D mono amp. The amp install diagram is causing me a little confusion.
According to the wiring wizard diagram below, it should be wired like this:
http://www.sonicelectronix.com/product/img/subwoofer_wiring/2_subs_DVC_2_ohm_mono.jpg
where the 2 wires go to 2 speaker connections on a mono amp, but this amp has 4 connections for 2 speakers. Is that for wiring two 4ohm speakers?

Should I wire the subs in parallel and hook them up to the connections that go to where it says Subwoofer (L+R) ?
I want to make sure im not getting jipped on the power by hooking them up wrong !
Thanks for any help.

PS, I tried to get the pics to show in the post but it says I cannot post attachments. Anyone know why?

^^ so you have one of these...

Link to exact model/version of woofers?

The speaker outs on your amp are paralleled internally, so you can either wire just like the diagram you linked to (using a single "+" and a single "-"), or you can wire each woofer to the amp on their own set of outputs.

To use both sets of outputs, you would ignore the wires going from woofer #2 to woofer #1 in the diagram, and would instead wire the leads from woofer #2 to one set of pos. and neg. inputs, while wiring woofer #1 to the other set. Woofer #1 would be wired just as they show, with woofer #2 copied and pasted right next to it.

Yes thats the correct amp.
The subs are Alpine SWS-12D2 Type-S 12" Dual 2-Ohm 500WRMS

Then you'll want to wire them as Jethro said- wire the voice coils on each woofer in series (for a 4 ohm load per sub) and then wire the two subs together in parallel for a 2 ohm load at the amp.

You can wire them up to one another inside your enclosure like this (option #2):

...and then run one pair of positive and negative wires from your enclosure to either set of positive and negative terminals on the amp.

Thanks Jethro.

So please correct me if im worng, basically theres two ways of 'paralleling' them here, either using 4 wires to the amp, so that each sub is wired directly to the amp, or wiring the subs themselves in parallel and then running just 2 wires to the amp.
And either way the amp still sees a 2ohm load?

The two sets of terminals are connected together inside the amp's heat sink (provided for convenience) and wiring the pair of subs at 2 ohms to one terminal or wiring one woofer at 4 ohms to each individual terminal amounts to the same load for your amp, though the latter option requires more wire to be run.

OK thanks for the replies. I think I get it. Wire them up like this

and then choose a pair of pos/neg to hook up the two wires.
( BTW, that image was scanned from the booklet that came with the sub )
