Noise!!!

[TallTom]

I've just set up my speakers into my amp but when i turn the engine I get a sqeaky noise, very thrustrating. I have checked the ground and whereva i put it it does not stop. The phono leads are also running seperatly to the power cable. I even got a filter that you put the phono leads in and then plug into the amp but still problem.
Can anyone help please??
Thanks

squeaky noise?? is it like a hissing noise or how they say white noise??

[TallTom]

i think its white noise, it changes as you you rev it???

bad earth on the alternator or the earth on the amp maybe, could be a sign that the alternator is on the way out too

[TallTom]

I've checked the earth on amp. How can I check the earth on the alternator?

very bad earth mate, i used the screw holding the back seats in place. but it wasnt very good for my mate he also got this noise. scrath some paint off inside boot, and slap a screw/bolt in there.

where is the best place to earth it on a saxo mate?

[Predator_R32]

have a look in the FAQs

there is no best place just as long as its on the chassis and the paint is ground down to the metal :y:

[TallTom]

I have got the earth in a good place. I've rubbed down the paint and drilled a hole in the boot and earthed to a bolt through that.
Anyone know any other suggestions?

where exactly is it earthed mate, could be earthed in a place near a power wire which in turn could cause interference

[carter]

it was the amp that was faulty on mine not the earth, tried a different amp and its fine

[TallTom]

Its earthed in the boot near no wires. Im starting to think its the amp cause its a cheap one i got off ebay 'silversonic'. But it worked fine in my old car. Hmmm any ideas why this is.
