Unhappy Confused with amp and subs

Hey guys this is my first post in this website.

I have a volfenhag zx-8400 amp and I am thinking of buying 2 kicker 07CVRs in original kicker box. But the thing is the amp is stable bridged at 4 ohm and the subs are 2 ohm so there is no way i can achieve 4 ohm. So i went to a local car audio dealer and he told me I can put the subs in separate channels.

Is it true that if you have DUAL 2 OHM sub woofer you can just use one of its coil and connect it directly to one of the channel in the amp and it would give you 2 Ohm? So leaving the other coil untouched just one coil being used?

He said if i do it for both of them like that i would get 2 ohm per channel because my amp is stable at 2 ohm if you don't bridge it.

get two single 2ohm subs or dual 1 ohm

Do not let a coil go unused it will kill it in the end and it wound sound as nice

Use this here Subwoofer Wiring Diagrams, Two 1 ohm Dual Voice Coil (DVC) Speakers

You will have to wire the voice coils on each sub in series to present a 4 ohm load on each channel. That will leave you with 200 watts per sub.

so there is no way to get two ohm from a dual voice coil unless i wire them together? right?

thats right. You need an amp that is 2 ohm stable bridged

OR, better yet, ONE of those amps on Each CVR.

you can also use an accumatch to fake the ohms to the amp

but in the kicker CVRs the dual voice coil doesn't mean physically there is two voice coil it just there as a dummy for more wiring flexibility. Why can't i just use one of the coil and plug it in directly to the amp resulting in a 2 ohm load. :S

HUH? Dual voice coil means just that, 2 voice coils. Powering only one will drastically reduce output and kill the subs much faster.
