Ok I got the Basslink, now what?

How do I connect the battery to the amp? I dont want a cable going across my car so it is obvious.

After I connect the battery then what is next?

What parts do I need? Just connect the two connectors I got with my basslink to the factory amp? I read the write-up on the front page, but it doesnt say anything about how to connect te car battery to the speakers.

thanks in advance

Circuit City said they would do it for $65 but they would need to tap into my headunit.
