I know alot has changed but the math and physics for hooking up speakers is still pretty much the same. Here's the impedances for wiring just one speaker. Just repeat the wiring for the other speaker to get a matched pair.
1. If you wire both coils in parallel on one speaker it will give you a 2 ohm load. (+ to + and - to -)
2. If you wire each coil in series it will give you 8 ohms on that one speaker. (+ to - and + to - on each coil)
3. If you wire just one voice coil it will give you 4 ohms on that one speaker. (+ and - from one coil)
Once you figured out how to wire each speaker, you can decide how you want to wire them together to get the desired impedance to your amp.
1. 4 ohm load - Use the 8 ohm configuration above (2) then wire them in parallel.
2. 2 ohm load - Use the 4 ohm configuration above (3) then wire them in parallel.
3. 1 ohm load - Use the 2 ohm configuration above (1) then wire them in parallel. That would be: + to + to + to + on all of your coils and - to - to - to - on the same coils. The + side hooked up to our amps + side and the - side hooked up to the - side of your amp.
I would recommend the 1 ohm load to get the most out of your amp. Give a holler if you need more help.
