Hello, in my current vehicle I have installed my Active Pyle Subwoofer again. Unfortunately, for this sub the music source for the rear speakers is used because the original Radio/Navi has no specific output. Now I am looking for a possibility to switch off this subwoofer if necessary also during the ride. Just if you want to listen to radio or messages it can be quite casual with the bass in the background. My previous ideas were either to move a switch from the trunk forward to interrupt the voltage or to use a Cinch switch from the Hi-Fi department which then switches between Cinch from the Sub and Nix and thus interrupts the sound transmission. (though this was thought of at http://www.conrad.de/…/2-port-Cinch-Audio-Switch-SpeaKa-AC1-Black) Of course, now with the topic Cinch switch so thoughts come to me because of noise from mobile phone or other sources due to perhaps bad shielding. Of course I could also repeatedly activate the rotary controller of the amplifier but the fine setting after it is really annoying (unless one can solve the volume switch here anyway cheaply) but if someone asks for the greetings
