[QUOTE="James-TT, post: 8791683, member: 686024"] Hello all, I’m new to this forum and start off with a problem I need help with, so sorry for that. I have installed a sound upgrade in the TT consisting of Hertz 2way in the doors, and a JL audio Subwoofer in the boot. These are running from a 4 channel amp and a mono amp. The source is from Apple CarPlay via a PX6 android unit. My problem is I have an intermittent very high pitch buzz coming from both door speakers and tweeters. It happens roughly every 20 seconds and lasts for 5/6 seconds at a time then goes away. The engine needs to be on for this to happen. So far I have double checked my amps ground, both amps are in a splitter block then a single ground to the chassis. I’ve unplugged the RCAs from the HU, but the noise remains. I’ve unplugged the RCAs from the amp, but the noise remains. Unplugging the RCAs doesn’t get rid of the intermittent buzz, but it is quieter. the only way I can have the HU on without the buzz is when the engine is off. I’m out of ideas. tia James. [/QUOTE]
