[QUOTE="Ninerfan, post: 8320183, member: 663285"] I'm trying to DIY a tailgating set up to run my TV audio through an old car stereo (not installed). I don't always go in the same vehicle to the games, so I want something portable. The stereo is a Pioneer DEH P-3300 powered by a computer power supply unit (yellow to power, black to ground with the green spliced into the ground). The TV is a 32" Vizio flat panel LED with a headphone jack audio out. The TV audio out is connected to the stereo through headphone jack to the Pioneer IP-BUS input. The speakers are from a Sony HTIB, including the sub-woofer. The TV and the stereo are plugged into a Belkin 1875 watt power strip. The system will be connected to a 750 watt inverter or Honda EU2000. As tested, the system is plugged into a home outlet. My problem, when I connect the set up to my phone or iPod using the "AUX", the sound is clear, no noise. However, when I connect the set up to the TV I get a steady buzz, but only on the "AUX" setting. I changed the speakers, rotated the speakers, and changed the positive/negative to the speakers. I suspect it is a ground loop issue because the buzz is not as loud when I plug the stereo into a three-to-two prong ungrounded adapter. I'm wondering if anyone has any other ideas before I nickel and dime myself into oblivion. [/QUOTE]
