Double It 500mA * 2 = 1 Amp
Interference The DC should not cause problems with the AC. The AC may interfere with the DC, but the DC circuits in cars are usually filtered to remove alternator whine. If it does become an issue, just shoot another cheap filter in.

Thanks for the clarifiation on the doubling question Switch controlling relay? - Page 2 -- posted image.
As for the intereference again, it's (the "DC circuit") actually going into a case where audio equipment will reside and the switch/relay configuarion is to turn on/off fans which will cool the equipment inside the case. That's why I want to make sure that the relays won't interfere with the audio because there's nothing like playing music to a crowd of people and suddenly "POP!!" when I push the button to turn on the fans.

The only way to truly find out is to try it. If there is a pop, turn on the fans first and then the music
