Dear All,
I just purchased the above and have installed it in my car yesterday. Everything went well except some humming noise on engine start or accelerating.
I've also installed a pair of ground loop isolators from the pre-amp output but this only reduce the problem a little. There is still some humming noise when listening to classical scores (with plenty of silence).
Anyway to overcome this annoying problem?
BTW, I hook up the HU this way:
Red - to vehicle's ACC +12V
Yellow - to vehicle's battery + terminal
Black - to vehicle's body ground
Some accessory shop told me to connect both Red and Yellow together to battery direct but this will not turn off the HU (sapping battery power).
