Hi everyone, I just picked up a kenwood KAC819 mono subwoofer amp. I had circuit city install it, and it looks like my One 12' sub is hooked up to basic speaker connections. I noticed there are 4 sets of speaker connections on it. Above the speaker connectors it says 'Speaker Output" for the middle 2 connections(+ & -) and a sigma servo connection for + & - on each side of the 2 middle connnections. Anyone happen to know what this is, If its something i should hook up and how i would hook up my sub to it correctly?
Heres a link to the amp justt incase anyone isnt sure about the amp i'm talking about.
Thanks for any comments
