dual voice coils allow you to wire for different levels of impedance, it also changes the level power of you can use, if one voice coil is rated at 300w then two of the same in a sub let it handle 600, more power more sound, basically. Also when you have 2 4ohm voice coils the sub is wired for either an 8 or 2 ohm load depending on if you wire the voice coils in series or parallel, and if you only have one then you can only produce a 4ohm load. i hope this makes sense its 5am i just woke up hahahaha.
Example, my amp makes the most power at 1ohm, so i got a sub with 2 2ohm voice coils this way when i wire it parallel it provides a 1ohm load to the amp allowing me to get the most power possible from it. with the 2 voice coils i get about 700rms out of the amp, if i only had 1 of them then id only get about 350w.
ohms are the level of resistance created by the voice coil, the lest resistance the more power that can flow, but not all amps are 1 ohm stable and alot of multi channel amps are only 4ohm stable. it's not to tricky to get a handle on, there are lots of right up on the web about, just google 'ohms' and find something related to audio, then do some reading up, a good understanding of this will be a big help through out the entire time you spend with stereos.

if you plan is to stay with the one sub you'll likely find it cheaper to buy a 2 channel amp that can be bridged at 4 ohms, find one that makes around the 300RMS mark when bridged into 4ohm, these are generally much smaller the mono amps and you have to understand that a mono calls d amp rated at 300w at 4ohm is more then likely designed to put out over 1000RMS at one ohm so its gonna be like $1000 there are some small single channel amp you could consider..
Here are some examples of what to look at getting.... some are 2ch some are mono... just read the specs for them and you'll get an idea of how the 2ch stacks up next to the mono
MTX Thunder TC3002 2-channel car amplifier 75 watts RMS x 2 at Crutchfield.com
Rockford Fosgate Punch P325.2 2-channel car amplifier 80 watts RMS x 2 at Crutchfield.com

also when buying it might not be a bad idea to browse the classifieds on here... there is some kick *** gear for ridiculous prices!!!!! plus then you get the info on how it would work from who you are buying it from...

That would be why the TC3002 and TC2002 were suggested for 300 Watts RMS and 200 Watts RMS (respectively) when they're bridged at 4 ohms.

It will be cheaper to buy a 2 channel that will do 300 watts rms at 4 ohms then it will be to buy a mono that does 300 watts at 4 ohms. However, if you are planning on adding another sub, then you will want to look for that mono that can do 300 watts at 4 ohms for upgradeablility.

Ok
I have narrowed it down to 5 amps that i can get locally for my price range.
They are all 2 channel amps like most of you suggested.
1. Exile X300.2 $199 CAD 300W Bridged at 4 ohm(seems like alot)
2. MTX TC 2002 $183 CAD 200W Bridged at 4 ohm
3. JBL GTO 75.2II $183 CAD 97W Bridged at 4 ohm
4. Phoenix Gold Octane R252 $139 CAD 150W Bridged at 4ohm
5. Pioneer GM 3300TT $112 CAD 150W Bridged at 4 ohm
Which of these seems to be the best deal?
They will be powering an 8" single coil 4 ohm sub of 150- 200 Watt.
I will not be adding more subs in the future.
Thanks

Are you changing your woofer now? You had posted it was an MTX MZS series woofer (handling 300 watts RMS).
