Any electrical type peeps out there wanna help me with a problem? There was a humming sound coming fro the speakers along with alternator noise when the engine is running. This only happens when I have the power plugged into the tablet. If the tablet is running off of its own battery and not plugged in there is zero hum or whine from alternator. I purchased a ground loop isolator for the power plug the tablet is getting it's power from. This took care of the alternator whine but the low pitched hum is there still present at high volume. Any ideas?

I bought an rca ground loop isolator from radio Shack today and installed it in between the volume control and the amp and it's completely gone. Perfect. Now 100% happy. Not sure if I needed the first one now that I put on the power socket but it's perfect now so I ain't gonna mess with it.

I've had this problem before while using the 3.5mm jack when my phone was plugged in. I bought a Bluetooth receiver that connected to my stereo & now use that for audio & have no more issues. It also makes removing the device a little easier.
