Rca bass control knob? Rca splitter? NOOB Please read!
Ok so my gps head unit only has one set of red and white rca outputs for the subwoofers. The factory shaker 500 subs have been connected for now but I'm adding in two 10 inch subs for the trunk, separate amp.
Can I buy 2 rca "y" splitters to allow me to connect both sets of subs? One will go in the red hu output and the other in the white Hu output? Not sure if the signals come out of both.
Also providing that does work, I've heard about an rca bass control knob allowing you to adjust the amp gain on the fly. I can see this being useful for my situation as I'm probably not going to have the factory subs as loud as the aftermarket trunk ones to avoid distortion. Do these bass controls allow you to lower the bass or only add?
I'm a noob at this but eager to learn, any advice would be helpful!
