Hi guys. I have a corsa opc /Vauxhall vxr2013. And I installed a pumpkin headunit, focal performance 165 v1 last editiom, an nvx vad 11005 amp. And 4 gauge wiring kit.
Power wires and RCAs run on different sides of the car,
For ground to the amp I sanded the body beneath the rear seatbelt bolt and screwed the bolt back on the cable. (Also made sure that it's good) Also gave the head unit a sperate ground trying to fix the problem, aslo tried different RCAs,
Now the problem is: I have this annoying humm and slight alternator hiss from the front focal's that goes away when I turn off the headlights or press the brakes. (The alternator hiss still stays a little).
If anyone has a clue. I'll greatly appreciate any help![🙏 🙏](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f64f.png)
. I believe it has something to do with ground problem
