Hey! I have a question for you guys! I have a sub and amp and am gonna install it. Before I can, i have a question....do I need a LOC? Thanks!
In you are wiring into the stock radio, then yes you'll need one, and you'll tap into the rear speaker wires for your signal. However there's likely one already built into your amplifier. Usually if there's "high input" or similar on the amp that's what it is used for.
