Ground Q/A sticky

are you trying this stuff with the car off? Is your car in ACC or just ignition on? 1968 VW Beetle

i would turn it off whenever i had 2 make an adjustment, but it was just ignition on, whats ACC?

ACC is accessories. When your testing your system you should have your ignition switched over to ACC. This turns off most everything but you can still run your system. In my car if I just have the ignition on then I can hear a slight noise due to my ignition coil. Usually starting the car stops it or turning the music on prevents you from hearing it. Try testing with the car started or in ACC mode.1968 VW Beetle

Question: 06 Honda Pilot. Added a kicker 4 channel and a fosaget 2 channel off the stock radio. Using Tsunami hi to low at the headunit. And when the volume is down and you goto put into gear you get what sounds like a reverb coming from just the sub. Happens about every 2 minutes or as you drive. I have tried an noise filter and had no success.I have adjusted gains, swapped rcas, reground both the battery and the 2 amps,. ANY suggestions would be most appreciated. Thanks............................ 

OK you said it happens every 2 min? Time it see if it's predictable. If so you need to find something in the car that electronically goes off every 2 min or what ever the time may be. Check your car manual and what ever else you can think of to track it down. Could be some radio freq that is bleeding over to your speakers which means something isn't grounded right or laying to close to something else...that would be my guess anyway. 1968 VW Beetle

alright ill give that a shot, i never did it with the car on, jus the ACC i believe... i think i know what the problem is.. a ground loop. i think my RCA's are causin the problem. i was informed by a friend that i should splice the RCA a bit and try and ground that to the chassis to see if the humming stops when the tracks change, hopefully that works..... but i will give that a shot when i try it again and keep u posted.. thanks again

if you do that you could make things worse. You could either buy better RCA's or buy some that come with a ground wire. Pricey but if you end up borking the ones you have you might end up having to buy new ones anyway. SOme people say an RCA is an RCA but there are some really good ones out there. Other then shielded and good connectors, there isn't much different between one RCA and another...not when you compare the prices of some places anyway. Monster cable i think is over rated but /shrug thats me :)1968 VW Beetle

lol, i get noise when my air conditioner clicks on.Proudly stuffing large packages into small boxes since 1983.

Hello all-    I have a sirius starmate that I recently installed in my car(1998 Honda Civic). I was using the supplied cigarette adaptor to power it. It had bad alternator noise then, and now that I've hardwired it to the car's radio harness, the noise has not gone away. The noise was present when i was using the wireless FM transmitter, and it didn't change when i switched it to a wired fm transmitter. I don't get any noise when listening to the cd player, or when listening to AM or FM radio, just when listening to satellite radio. Any insight on how to solve this problem would be appreciated -Thanks!
