I have a 04 infiniti g35x and i have the pioneer z1. It was working great for about a year and now i notice my passenger front right speaker keeps coming on and off periodically. It could turn off and turn back on in a few seconds. I turn up volume up or down and it could come back on. Its wierd, I was thinking to check the speaker connection to the wire in the door panel? Whats the problem?

speakers most likely worn out. definitly check the connections at the deck before pulling the door off. but be ready to replace ur factory speakers

so i got to take apart my center console again. i dont even really know which wire connection am i looking at. looking at a speaker and seeing if 2 wires are connected to it is easier. i have taken the center console before to try and connection my vss wire before, but then i took it to the shop because they forgot to install that so it works now.

This is odd, I had to replace my JL amp and the same thing is happening to me on my right side, but the volume goes lower not off. So i check it out thinking it's the amp swapped RCA cables no help. Where the Amp is i had to use a pliers to take the RCA cable, so when the pliers touch the right RCA cable and the amp,the volume would come back. So Thinking the cable is bad i just ground both RCA outside shells together.Now it works fine,but i know there is a problem either with the cables or the Z1.

It never happened with the old JL amp, just started two weeks ago,so i have more trouble shooting to do but it's cold out.
