My car has a Factory Subwoofer which I will replacing with an aftermarket one. I read on another forum to use a LLC hooked up to the factory sub wires for signal. In the past I have achieved this style hook up the same way everyone has, a LOC to the left and right rear speakers. I am just unsure if I REALLY need a LLC or is a standard LOC will do since this is my first time hooking up to a factory subwoofers speaker wires. 2002 GS430 getting: ED 13Ov.2 Subwoofer in factory Sub location (IB in Rear Deck) Kenwood KCA-X10D Amp PAC Trunk-Loc (If a LOC will do which I think it should)
