hooking up my system.

Well first off, those subs aren't going to take 1000 watts a piece, rated at 800 peak, so realistically, cut that at least in half for an actual power handling rating. Second, forget that legacy amp, it's going to do nothing but disappoint you.

I would say find you a decent mono amp that will put out around 800 rms @ 2 ohms for those subs and wire it as shown above.

He has his setup wired to give a 2 ohm load.  If you wired it like you described you'd end up with a .5 ohm load which that amp isn't going to handle.  Running at 2 ohms will be your best option for that equipment.  Make sure you put them in a solid enclosure that's of proper design for them and you should be happy with it.

Where did you get that they give the same load?  I said in my previous post everything in parallel gives you .5 ohms which is too low for that amp.  Wire in series/parallel and you'll get  the desired 2 ohm load.
