Hey Everyone..

Hopefully, someone has an answer to this. Does anyone know why theres always static when i listen to the radio in the morning..and when i plug my cell phone charger into the cigarette outlet?
Its starting to get annoying. I would turn the radio on in the morning and there would be static. It would last for a little bit and then would come back every now and then. OTher times, when i have the car charger in the outlet, there's static but when i take it out, its ok.

I have an Alpine 7893

Does anyone have any idea what could cause this?

Also, there's minor engine noise in the morning as well.. that goes away as the day goes on.. ???

 

Sounds like a ground issue to me. If not, you might try one of those ground loop isolators.

 

What should i be looking at in regards to the ground issue? Loose ground? Grounded to the wrong spot?

what a ground loop isolater..

Thanks!

 

Try grounding the HU to the chassis.

 

More than likely your harness just used the existing ground which will sometime work fine. Sometime noise still exists because it is not a direct ground to the chassis. I would instead take the ground from your HU and us a short wire to go directly to a seperate location. If that doesn't work, this might be a last resort. PAC SNF-3

 

HM.. i never thought about it as being a problem with the harness.. I forgot what the wires look like on the harness.. would i look for the ground wire and then splice a wire to the ground and the other end to the chassis.. HM.. any suggestions on how to do this? Sorry to be so bothersome.. i just don't wanna mess anything up.

At first, whati thought it may be was 1 of two things.. Tell me what you think.

first i thought that the antenna lead, which was behind the radio/dash was interfering with something.. and causing the static back there..

second, the constant power lead that goes directly to the battery from the back of the radio was too close to the rca output/sub wires

what do you all think?

 

It is really going to be trial and error. I wish I could say do this. Yes I would first try to splice in the ground like you said. If that doesn't work, cut the ground from the harness and go direct. Be sure to scrape the paint away from the chassis so it is metal on metal. If that doesn't work, maybe try to run a new power direct from the battery. You could run it outside temporarily to see if it works first.

 

OK i'll take a stab at it either tonight or over the weekend.. i'll let you know how it goes.. THANKS!!! i appreciate your input..
