Just wire it in series on the back of the woofer (coil 1 terminals have the white dot and coil 2 terminals don't have a dot. Run one wire from the black terminal w/ white dot to the red terminal with no dot. Run the amp - wire to the speaker black terminal with no dot. Run the amp + wire to the speaker red terminal with a dot). Run one set of wires out to the amp (one pos, one neg). Hook it to the amp (whatever terminals pos and neg show to be in bridged mode), and switch the amp over to "bridged". This will achieve a 4 ohm load at the amp and you can safely push it. If you are confused, just look at your manual, if you don't have it, hit the link below to get it:
