Wiring Confusion

[blgaudio 10+ year member]

Ok,

I have a Audiobahn 1051T 10" sub that I want to hook up to a Kole Audio 620 watt amp. How do I wire the voice coils. The voice coils are 4ohms each and my amp is 2ohms stable do I wire it for a 2ohm load or a 8ohm load. Why Im confused is because on Rockford Fosgate's wiring help page they state that a 8ohm sub has a red dot for speaker posative polarity and no dot for ground as mine has does this mean it needs a 8ohm load? Thanks P.S will the amp be to much for this sub?

If that amp is 620 watts MAX you'll be fine. Wire the sub for 2Ohm to get the most out of the amp, especially if you know it's two ohm stable.
