Hey there i got an 86 corolla 4 door liftback for free lol it runs great but im going to be installing a system into it does anyone know where a good ground is, I have already installed the system. but everytime i load a cd i can hear distortion come from the subs also whenever i put the blinker on i hear a pop sorta like when you shut off the sub its wierd it happens quite often. i tried 2 different spots the(the seat mounting and in the back hatch) i get the same sound from both spots. I also tried new rca jacks aswell. Im really stumped on this
Thanks for your help
