Amp and Sub to 09 Liberty stock radio?

I have an 09 Liberty with the stock single disc w/sirius sat radio. I also have a single 10" sub and a 500w amp (didn't want much, just a lil more bass). How do I connect this to the stock system in my Liberty, I really don't want to change the head unit. Is there an adapter for the connector behind the radio, or what do I do?

You will need a 4 channel adapter to convert the speaker level audio to lo level audio. I installed this one.

This is the wiring diagram. All KK's have the white connector that contains the speaker level out.

you can get the plug-n-play harness from coastaltech. this is better than the adapter. check out the lockpic at their site: http://www.coastaletech.com/LIBERTY_INSTALL.htm

Please explain how that plug and play harness works? Do you use the audio outputs? Signal?

plug and play means it plugs directly into the head unit and voila, you have your RCA outs....BUT I don't think this is the correct harness.

I have that harness installed above along with the lockpic. I just went out and looked at it. It says video/audio output on the one set of RCAs. I measured the mV across the + and - it doesn't seem like a strong enough signal. My amp wants at least 200mV but I was measuring in the 100 range. What would be the correct harness? There is an open ended white plug that I believe has the speaker leads. I was wondering if I should use the speaker leads and a line level converter or if I should use those RCAs like above and go directly to the amp with them.
