hi, i just bought a astra g 1.4 16v, bought it off a friend i will upload pictures tomorrow on a diffrent thread, any way im have a strange problem i get interferance from the headunit and some are random. like when i close the faceplate it kick out some back and randomly does it. its hard to explain, its got a great earth. by the way im running 2x15s juices and a juice 2400 amp and 6 gadge wiring kit. its becoming so annoying i cant get rip of the noise. its ok when i turn it up really loud but is i turn the sound down its rather loud and annoying. its not when i rev the car or anything like that, its only when i mess about with head unit. but it still does it if i change the headunit. so was wondering if i need thicker wires?
