Could be a newb question, not to sure
Well, Ive browsed around on the forums quite a bit... And im wondering about the dual x ohm subs, What kinda of amp would you need to power these, multiple channels? Or how exactly do they hook up, I want to purchase something new for my car, but I'm not "extremely" literate when it comes to this, I'm still trying to learn the ins/outs about all of this stuff. If anyone dosnt mind taking a bit of time to explain, or possibly point me towards a good site with information, it would be greatly appreciated.

With a dual voice coil sub, you can hook up the coils in parallel or in series.
In parallel, the impedance is half of one voice coil impedance. In parallel, the + of each coil and the - of each coil are wired together then hooked up to the amp (that is the + wire of one coil goes to + wire of the other coil and the - wire goes to the - wire, then the two + wires go to the + terminal on the amp and the two - wires go to the - terminal on the amp).
In series, the impedance is twice the impedance of one voice coil. In series, the + of one coil is hooked to the - of another coil then the remaining + and - connections are hooked to one channel of the amplifer.
You can hook up the voice coils in either configuration to any amp channel that supports that impedance. (both coils to one channel)
You can hook up each coil to a seperate amp. (2 amps - ensure that the amps are strappable or you will blow your sub)
You can hook up the coils to a bridgeable amp. This usually doubles the power of the single channel outputs but at twice the impedance of a single channel (single channel is 2 ohms, then bridged it would be 4 ohm input)
Some mono amplifiers have 2 sets of terminals that are wired parallel internally. You can hook up one voice coil to each terminal and it will be parallel inside the amplifier (the same as wiring the coils in parallel and hooking them up to one channel of the amplifier).
Theres a lot of information because there are many methods of hooking up a dual voice coil sub. If you have more than 1 dual voice coil sub, you can then go on to hook the subs in parallel or in series and so on.
The most important thing is to ensure that you match the impedance of your subwoofer to the impedance of your amplifier (don't wire your subs to a lower impedance than that which the amp can operate at).

Ahhh okay, I actually understood all of that.... Thank you very much for the information, Ive been interested in upgrading my current system to something MUCH louder (SPL). Ill get a few pics of my current system once I resize the pictures. Im still new to all the technical terminology, Ive still got the same system ive had since 2001 (I simply bought it all in one big package). This time, Ive deceided to do it all myself, hopefully save myself some cash in the process.
I have a current box, sealed, 2 MTX Thundercat 6000's with a 4-channel BOSS AUDIO amp, not sure of the model name or anything, its rated at 175x4 or so it tells me on the side near the terminals.

This is a great forum if you're ever in a bind.
This is a great forum if you're ever in a bind.My first system was a package, it sounded ok, but still, not to great. My current system (which is only about another $100 more) sounds MUCH MUCH better. I love my deck, my sub, and the time it took researching was well worth it.

Yeah I have been doing TONS of research on everything. Trying to learn as much as possible before I go dumping a couple hundered (Upwards of a grand) into a system. Its always been a "passion" so to say, and Finally I have some extra cash to throw into it. I own a small '92 Dodge Colt Very small car, No room at all in the hatch for anything. Im looking at 1x15", or possibly going with 2x12".
Im leaning slightly more towards a 15, just for simplicity reasons, Im kinda sold on the Clarion DPX 1150... Still unsure of what sub I want, Any one with any suggestions feel free
Thanks for the responses as well guys, seems like a great website.

Clarion DPX 11500, Im looking at that one right now... But their are soo many out their... Im really up for anything right now, Ive heard great reviews on the Clarion brand.. Ill be going to pick up a DXZ575USB head unit on Friday, I can get some decent prices on things at a local shop here in town, If you guys have any advice at all, im all ears, Im aiming at loud loud loud bass 
Thanks guys.
Derek

Alright im in the midst's of uploading a video of my subs in action, Im pretty sure one is blown, or at least near that... They dont move in sync, Anywho, I dont know of any where else than Youtube, so I hope that aint a problem..
