Samsung Galaxy 4 7" Tablet install

What about the positive wire going to the amp? is it parallel with the RCAs? Try to put them in a separate direction, if so, check your tablet, put some insulator on every side of it like a thin rubber or a foam. Try also to completely remove the whole tablet from the center console and play some music then check if the hissing sound is still there.

The 12V+ wire and 12V+ ignition switched (remote) wire are both from the radio harness (metra kit harness plugs for Toyota) and are parallel with the RCAs, they (along with the speaker wires from amp) are in a bundle that is hidden under the center console and exit that to under the passenger side seat to amp and volume control knob. I've read a few times that one should run a separate 12V+ constant directly from the battery to the amp but I have not tried that as the amp is only <40W (actual) RMS per channel. Was hoping I could use the power supplied by the radio harness. It was OK for the amp in the stock head unit... Perhaps it is time to try that and route it under the passenger side door trim. I'm also thinking about getting a different amp, but running the cable will be free, the amp kit I am looking at will be another $50. Sooo I will probably do the +12V amp wire this week some time.

The hissing is present with the tablet out of the dash. The only time it is not present is when the volume control knob is turned all the way up, then its crystal clear.
