Ground Q/A sticky

Hello all, i have a quick question. i am currently re- wiring up my car. Now just to inform you these tests where done with the deck on a mat not installed, letting the wiring run free but not touching anything(this could also be the problem...) One problem i encountered was that once the audio started to play, everytime i changed a track the speakers would make a poppin sound and u could see the speaker move in then pop out ;s;s.. could that be a bad ground? bad connection? Also the amp would not turn on, i have the wire connected to turn on the amp.. i was thinkin maybe the wire got clipped while puttin back in my interior so i was going to try a direct connection from the deck to the amp.. Any suggestions? If anyone could help me out it would be greatly appreciated.. Thank you

could it be that the deck needs to be grounded as well. There is usually a ground wire that comes from the wiring harness of the deck that needs to be hooked up as well but i think some if not all decks are also grounded by the body of the deck by being installed. Might want to run another ground wire and touch the deck metal and see if that helps. 1968 VW Beetle

i did that, on my car's wiring harness the ground on there is "bad" so what i did was jus run a seperate wire to ground, for both the stock wirin harness and my deck ground to the same place, the deck turns on.. but would a bad ground on the deck affect the amp? cause i know when i had one of the grounds in a spot where i clearly knew would be crap but i tired it anyone, the deck would turn off, or adjust.. now it says adjust or if its adjusted still no amp and that kickin problem is still there ;s

Sounds like your getting some sort of feedback. My speakers pop a bit when I turn off my deck but not when i change tracks. Best thing i can offer is go back over all of your connections. Verify nothing is touching thats not suppose to be like additional speaker wires. Check your grounds again and make sure you are really getting a full on ground. What direct connection from the deck to the amp are you talking about? There is usually a blue wire that powers the amp when the deck comes on. Get a test light and check to see if that wire is getting power to it when you turn the deck on. I read another post by someone that had a problem where that wire stopped powering his amps and decided that it was an internal problem with his deck. 1968 VW Beetle

Yes your wire is probably the blue/white wire I think on some models this wire is used for both amp and power antenna. Anyway, all I can sugest is recheck all wires and those that are not used make sure they are insulated so they can't touch anything. As for the ground, in most cases ya. if the deck has power then there is ground but it might not be a very good ground /shrug/ Also make sure none of your speaker wires or RCA plugs are near power wires. 1968 VW Beetle

No problem at all. I try to help as much as I would like someone to help me. Unfortunately my knowledge isn't as good on this subject as a lot of others is. I know the basics, high watts need big cables and good grounds :) YOu would be surprised what a bad ground could do. Especially on early cars like mine. Bad ground could account for about 70% of the problems people have. 1968 VW Beetle

i think i found the problem .. like one of the sticky's CHECK YOUR GROUND.. i grounded my deck and my harness to the E brake and works perfectly, the speakers dont pop loud anymore but the move a bit but u cant hear it.. THe only problem im having now is when i change tracks i am gettin humming sound, any idea on how to get rid of that? ive tried movin the connections off the ground but its still there
