Exclamation 8 Ohm Coils or 4 Ohm Coils? Need Some Help.

Hey guys I got a quick question I've got a Pioneer IMPP 12" subwoofer (TS-W1241DVC)

The link to this on the pioneer website is http://www.pioneerelectronics.com/PUSA/Products/CarAudioVideo/Subwoofers/Champion-Pro/TS-W1241DVC?tab=B so you can look at the specifications, they say that it's 2Ohm or 8Ohm Rated.

However on http://www.shopping.com/xPO-Pioneer-TS-W1241DVC#keyFeaturesArea this website say's its a 8 ohm (Dual Coil)

Now does that mean each coil is 8 ohms or that each coil is 4 ohms. Basically I'm trying to wire it up to a 2-channel amplifier which is only stable at 4 ohms and am checking out a couple different wiring options.

Any additional clarification on this would be great.

Thanks.

dual 4 ohm bro, not right for your amp. Look for a dual 2 ohm or single 4ohm sub.

Additionally if anyone know's what is the min air space behind the subwoofer should I have?

For instance I am in the design process of the subwoofer box but in my truck I need to angle the subwoofer in the front of the box so that it will fit comfortably in the truck while maintaining a 1-1.4 cubic feet of air space but I only have 10" width to work with so I need to angle the subwoofer so that it has plenty of room in front of it.

However if I do this the room in the box behind the woofer will be minimal, the air space will be correct but I'm wondering how it will effect the quality of the sound.

Yeah I know my amp I'm using now is a P.O.S. and am going to buy the correct one, I just got the subwoofer and amplifier for free so I could care less if I blow the up with my experiments.

Basically I'm using this free crap to test what would work the best in my truck 2003 dodge dakota single cab, I'm building a center console box for it but there is very limited space.

I should go with 2 10" woofers but I would just like to keep the one 12", this would be my third re-structuring of the subwoofer box itself.

But like I said I would rather destroy the free subwoofer and amplifier testing different designs before I go out and purchase the correct amplifier and woofer, well not the woofer I've got lots of these old 12" IMPPs to play around with.
