I was connecting an equalizer and it was working fine, but then i put it in another vehicle and everytime i turned it on or changed the station the entire system (speakers and subs) started popping, and sometimes when the music is playing the subs start to move on their own like if they were out of phase, anyone know what it could be? i tried rewiring the eq but it hasnt changed, im thinking it could the rcas but i dont know. Any info or help is appreciated thank u (quick note, i took off the eq and the system sounded good but i like having the eq involved so it helps keep me in control of the sound)
