[QUOTE="bangity, post: 8685480, member: 678141"] Hello, I have a 2 way component system setup (2 tweeters and 2 woofers), a Joying HU, a 600Watt Amp + a 400Watt standalone Sub. I run the power wire on the right and audio cables in the middle. I ran a 4 gauge power cable to the amp, another 10 gauge cable tapped into that for the 400watt sub. 10 gauge ground cable into the ground slot on the Amp + 4 gauge ground cable from that same slot into the ground of the car (bolt of the car passenger seat). I sanded and cleaned the bolt slot before I bolted it down. However, there is this buzzing sound only when the engine is running. It increases when I increased the boost/gain on the amp. It does not change with the RPM of the engine. I tried grounding the ground cables (both left + right audio output from the HU) onto the HU chassis (there is no RCA cables in the setup). But when I do this, there is no buzz but there is also no sounds. I then tried grouding the Ground cable of the HU itself onto the chassis but there is no changes (buzzing and sound still there). I tried different ground spots as well but no change. I have no other solutions. Prior to installing the 400watt standalone sub today, the buzzing was very minimal. But it has doubled since the addition of the sub. This is what I am using.
