I've got nothing but good things to say about Century Ford in Mt. Airy, MD. Alex Simmons was great to work with. I know the GM, Joe DiGeorgi, personally. He's a stand up guy.
Noob question here: I purchased Kit 16. Do I need to run a power cable from the powered sub to the battery, or does it draw power from the harness that's attached to the Kicker Key and the back to the head unit?
