The only way is to run one coil and thats not the way to go. just run a 4ohm load. In right encloser you'll be fine, but to get the max out of your amp you'll need a different sub.
I do not really understand how ohms work. I have a 2 ohm Kicker sub, its a Kicker enclosure so it's pre-wired from the box terminals to the sub and it says 2 ohms by the terminals. Is this presented as 2 ohms to the amp?
