Does that mean it's 2 ohms combined over the two channels ( 1 ohm per channel) that will give me 500 watts per channel. Or is it 500 watts @ 2 ohms on each channel?

500 watts @ 2 ohms on each channel
How you load an amp determines the amount of power out.
There is a trade off though, the lower the impedance (ohms) the more power is pushed as well as higher distortion and more heat is generated. The excessive heat will shorten the life of the amp.
For best overall performance, it's far better to get a higher powered amp and load it with 4 ohms than a lower powered amp and force it to push more power with a lower impedance (2 or less ohms) load.
If your total system power is 1000 watts RMS or more, you will need to:
1. Upgrade the alternator to a high output alternator
2. Upgrade to a heavy duty deep cycle battery
3. Upgrade the "Big 3" - that is to replace the power wire between the battery and alternator, the ground from the battery to the chassis and the ground strap from the engine/tranny to the chassis with at least 1/0 AWG wire.
Failure to do this will result in you replacing them anyway as the alternator will eventually fail.
Here is a guide that will calculate what size alternator and power wires you need http://www.datafilehost.com/download.php?file=6d26c621

That means you can power 500 watts Thur a 2 ohm voice coil per channel that is a lot of power. 0 ohms is a direct short circuit better use big speaker wire and even bigger power cable to power that amp. Warning hearing loss at high power levels! Now how much distortion?

it will give you 500 watts per channel at 2 ohms per channel.
