Still having strange sound from HEADUNIT

maybe not u never know but he gets m :shocked:y drift

the problem with earthing to a taillight is that the metal is very thin and think about what the actual thread of the light is held on by plastic (not a good conductor of electricity) and a very tiny amount of the thread contacts with the very thin piece of metal it is passing through
so you are relying on the bolt to create the earth which is not ideal
also connecting the earth directly to the battery in itself sounds a good idea however this can cause interference problems in itself in that it is more succeptible to alternator interference
move the speaker cables away from the power cable that will help
the little box you can buy is actually called a ground loop isolator and invariably these do not work
they plug in line on the rca coming from the h/u and do not actually eliminate the noise but effectively reduce it but as i said most of the time the do not work

Is it a Pioneer Headunit? The ground fuse in the HU for the RCAs blow causing a whine.

I had it, I grounded the RCAs like this -

its kenwood, havent still found the problem..

[rehu]

i placed grd on the backseat beltpoint now and still having this problem, i even placed rca's better etc.. everything now should be good.. strange.. maybe something on kenwood then..

[kells]

best plac eis on the boot floor under spare wheel, drill small hole and fit earth cable with a self tapping screw, make sure you grind off any paint so it makes contact..


oh and bin the kenwood buy a ALPINE

YES listen to the man

[rehu]

yeah i will throw away kenwood what i just bought with 200 euros?
sounds like a plan man..

it isnt about the earthing at amp, im 100% sure about that.. its something about either batterys grounding.. or headunits grounding is crappy..
