Verify I'm Making the Right Amp Decision
Just looking to get some verification that I've got everything correct and am making the right decision, as far as amp and wiring setup. I've read and read about amps, ohms, and wiring, and to be honest, it makes my head hurt.
So I've got some old school 10" Alpine Type Rs that are rated at 500 watts RMS each with dual 4-ohm voice coils, so I'd like to feed them 500 watts RMS each and keep everything at a 4-ohm load using a single amplifier. Here is a link to the subs I already have.

Here is a link to the amp I'd like to go with. It's a single channel amp that puts out 1000 Watts with a 4-ohm load.

And here is the wiring diagram of how I think I should have everything wired.
Everything look good and be able to provide what I'm looking for? Thanks for any help and advice.

That diagram is correct. What they're doing is connecting the two voice coils of each speaker in series effectively creating an 8-ohm speaker. Then they connect the two 8-ohm speakers in parallel to show a net 4-ohm load to the amplifier.
It would also work if reversed - wire each speaker's voice coils in parallel to create a 2-ohm speaker and then run the two speakers in series creating a 4-ohm load. There is no advantage in doing it either way... the results are identical.

From what I've read, these amps tend to be underrated. If this amp ends up putting out more power, am I playing with fire by already matching the subs with their max RMS power?

I don't know what you just said, but that's cool! As long as I have the correct wiring diagram to show me the way, I'll be alright.

Now it is also true that using an amp that produces more power than the speaker is rated to handle is probably better. As long as you don't turn up the volume beyond the speakers capability, you'll never have a problem. It's best to buy a speaker that can handle the most power you would ever want to hear (threshold of pain if you don't want to be able to hear when you get older... perhaps because you're married ) and then get an amp that can provide at least that much power cleanly.

I will probly end up having this setup not even turned up to its capabilities. But it's like horsepower. Just cause I may only be cruising around doesn't mean I don't want a lotta horsepower. It'll be nice to have it there if I ever wanna use its full potential.
