anyone ever heard of this?

Has anyone ever heard of this or any technique to wiring the remote.. This was not written by me but do you think its a good idea?

"I've spent most of tonight searching for this info, and came close to finding it here but wasn't completely satisfied with what I found. So here's my scenario.

I installed a few year old Sony amp which as far as I can tell does not have a low voltage remote turn on feature. The instructions call for 12v. However, as I was being lazy and I read somewhere else about using the positive wire from one of the speakers coming out of the HU, I decided to try this. I tapped into the speaker wires already as I am using the stock HU, and ran those to the high level input on my amp. I then ran about a 12" bit of wire from the positive lead of one of the speaker inputs (nearest to the amp) to the remote turn on on the amp. I metered the wire and it gives 0v with the car off, and 6v with the key at ACC (I didn't meter it with the car running). My amp turns on, I don't hear any pops, no noise from the sub, no noise from the speakers...it seems to work fine. But there was concern with this method of wiring on another forum, and as I said in all my searching I haven't found a concise answer to my scenario.

Do you guys think my setup is ok? Is it possible to cause any damage or feedback to the rest of the system using this method? The only downside I see (at this point!) to this method is that the amp is on even if the HU is off, which in my case isn't a problem as the HU is on 99.9% of the time I am in the car. And just to confirm, yes the amp turns off when the car is off.

Thanks!"

I do not think it's a good idea. It's only asking for problems.

look up at http://www.the12volt.com for wiring in a relay to do this

I totally understand what you're doing here, I don't know why most people haven't seen it. Bascially you've got it set up as if you'd wired your remote turn on lead to the 'acc' on your igntion. Nothing really wrong with it, as theres no current draw on that lead (so you dont need a relay), but it's not clean... thats all.

When you upgrade to a new head unit, it'll have a remote turn on wire, just run a wire to the amp then.

lol, ah, thats nothing like what the first post said..

the first post is talking about using the positive speaker output from the headunit, to turn on the amp... //content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif

Yeah, the first post is stupid. Plain and simple.

Might as well make a jumper from the positive wire input to the remote wire turn on.
