Remote Wire Question

[Jason Sybert 10+ year member]

I was talking to one of my car audio buddies at a local shop and i told him that my amp was picking up altornator noise. I told him that i had checked and changed the grounds RCAs ect. He asked me if i had changed the remote wire. I said "No, why?" he said "your remote wire is causing the feed back." i changed the remote wire and sure enough the noise went away.

I was wondering if it is just a wire to switch the amp on and off why was it causing the amp to have altornator noise?

I thought it would be like a relay.

I'm curious what you switched it to? Isn't a remote turn on lead a remote turn on lead??? I don't get it.

I put in anew wire from the HU to the remote wire connection of the amp. What i was wondering is if anyone has heard of the amp having altornator noise from the remote wire? and what causes it?

The only way that it would take away the noise is: You had it connected to something other than the head unit the first time that was generating noise OR, your original "heat unit to amplifier" remote wire had been pinched somewhere ie wire tied very tight to a signal cable causing induced noise through those cables.

yup, cause the remote wire is just a 12 + to power an internal relay to turn on your amp, it has nothing to do with alt. noise IMO. i can't see it being the problem, i would like to hear more about this because this sounds weird to me.
