Ok, so here's the story,
I have :
4x 6" alpine type R speakers, some cheapo sub and amp and a sony LCD headunit
I have ensured its all wired properly, all wires connecting to the headunit and soldered and heatshrinked.
All speakers are connected to a 4 channel amp and have individual RCA's.
Problem is that when all 4 speakers are pluged in, the speakers emit a buzzing sound intune with the alternator, when i unplug the back and just leave the front pluged in = no buzzing, and same if i unplug the fronts and leave the back pluged in...
I have bought a cap to put on the alternator but that has made a differance..
My friend from work thinks it might be the ground connected to the headunit and he thinks maybe i should connect it straight to the battery, and other people think that i should just get a bigger cap to put on the alternator.
the grounds on both of my amps are strong and well.
I am kinda leaning towards the ground on the headunit... maybe go down to jaycar and get a longer wire and connect it straight to the - on the battery?
Please give me some input, thanks heaps
Ian.
