ive put my amp in my boot but cant find a good earth, the problem im getting is a get a buzzing sound through speekers when engine is running. ive tried the normal earthing points u have sugguested but none have got rid of the buzzing sound!

Have you run the RCA and AUX leads down the same side of the car as the power cable? as that causes interferance and makes a buzzing sound...

I have earthed my amp underneath the rear seat.. underneath the hook that secured the base of the rear seat... make sure you scratch off the surface paint too, to reveal the bare metal and get a nice pukka connection

yea same as. i had a bad problem with buzzing from running cables down next to the main loom, i had to seperate cables and run power down one side, rc down the other side, and kept them all away from the main loom! hope this helps mate

I don't know how people end up putting all the cables down one side though? as it is easier to seperate them...

The gromet for the power cable is in the passenger footwell so makes sense to put it down the passenger side of the car... and there isn't much space in the top of the passenger footwell because of the fusebox, so running the wires from the back of the headunit (Remote cable, auxillaries) would be easier to put them down the drivers side... underneath the carpet...
Then you shouldn't have any issues with buzzing... and you don't have a massive buldge under your carpet

when i wire up a car i take the seats all out and then makes it easier to wire up remote and rcas up the middle and power down the passenger side, it only takes 5 minutes to take the seats out if you know what your doing

ive ran my rca cable down the other side to the mains and earthed it by the bolt at the bottom of the seats but there is still a slight buzzing sound!
