How do I bridge 2 subs to 2 ohms?

I'm in the process of hooking up a set of Alpine 12" Single-Voice-Coil 4-Ohm Subwoofers (Model: SWE-1242) to an alpine amp.  The RMS is 200w, and the max is 600w for each sub.  The amp specs for the alpine Model: MRP-M450 are as follows:

I've hooked everything up as seen in the following diagram

Is everything hooked up correctly?  How come the amp specs don't say

Max Power Watts per Channel (4 Ohms Bridged) 600

Your 2 single four ohm drivers will NOT yeild the 4ohm load you desire. Use 1 sub, or get 2, 4ohm DVC's

Option 1 (parallel/parallel) = 1 ohm load Voice coils wired in parallel, speakers wired in parallel Recommended Amplifier: Stable at 1 ohm mono

Option 2 (series/parallel) = 4 ohm load Voice coils wired in series, speakers wired in parallel Recommended Amplifier: Stable at 4, 2, or 1 ohm mono

This package deal was sold at Best Buy for 369.00 (box, subs and amp)

I take it that there is going to be alot of complaints coming back to them for selling an amp not capable of running the subs the sell.

Its also sold at crutchfield:

Did they incorrectly package this?

This is where the confusion is. You CANNOT get 600 watts out of this amp. It is rated at 400 watts @ 2 ohm or 220 watts @ 4 ohm. Also, you CANNOT bridge a mono amp. Bridging is when the left and right channels of an amplifier are connected via the outputs to essentially give you one mono amplifier.

The setup mentioned running both 4 ohm subs in parallel giving a 2 ohm load to the amp is correct. This would provide 200 watts to each sub which is what they should have.

Thanks for clearing things up for me everyone.  Can someone explain why the specs say "Max Power Watts per Channel (4 Ohms Bridged) 600"  if the amp cannot be bridged? 

Also which statement below is the same as saying:

1) Continuous Watts per Channel (2 Ohms) 200 x 2

Neither, since you are talking about stereo output relating to mono output.

Some amps will say: 200 watts @ 4 ohm stereo and 400 watts @ 4 ohm mono (bridged). Mind you, I don't personally know of any stereo or multichannel amp that will bridge at 2 ohms.

There are other amps that will tell you that their bridged output power is greater than the sum of their 4 ohm stereo output. It's all on how the manufacturer rates it.

In the end, your amp at 2 ohms and 400 watts mono to your two subs in parallel are a good match.

Now, I haven't seen the actual packaging...but I know that Alpine's advertising on their website lists the specs correctly for subs and amp for that package. I was actually looking into buying that for my girlfriend since she isn't trying to have serious bass in her vehicle. For $299, ya can't go too wrong.

The 600 watts bridged then is a typo.  I understand now, thankfully I don't have to take anything back to the store.  I take it that it's more common to run 2 single voice coil subs in a mono format?  When and why would someone run them in stereo?
