No voltage at Remote Lead?

[Darren5531 10+ year member]

I have no voltage at the remote lead but I get voltage at the power and ground. No voltage at the speaker terminals either. I have tried to research what to do and I read somewhere that you need to run it to a 12v source or something? What should I do?

Thanks

well if you dont get any voltage at the REM wire. then there is somthing wrong with the deck, or have you tried to disconect the wire and then check it again?

First question is where is the REM wire connected to ? REM output on the HU or did you wire it to something else?

I have the REM wire connected to the head unit. I can take pictures if that would help. Im going to go disconnect and then re connect it and see if that makes any difference. I read in the manual for my 225.2 that you can connect it straight to a 12v source? Im not really sure how to do this so any help would be greatly appercaited.

Thanks

You might of connected it to the wrong wire on your deck. My friend did that and we had no voltage at the remote lead. He connected it to a blue wire with a white strip and he was supposed to connect it to just the blue wire. Check to make sure its connected to the right wire.

It is connected to the blue wire and then I tried connecting it to a blue and black wire and still nothing so then I re-connected it to the normal just blue wire and didn't get anything. It might be my deck or some setting on my hu. Is there anyway I can go around the hu cuase isn't the rem wire just to tell the amp when to turn on and off?

Thanks

You can connect that lead to a fuse in your fusebox that only has power when the ignition is keyed

 

OR

 

You can wire a power lead to the battery that includes a toggle switch so you can arm/disarm the amp(s) manually.

Yes, the remote accessory activation output from your HU is nothing more than a circuit that tells whatever accessories you have connected to it to turn on and off with the HU.

So if I was just going to do a test and see if it is the rem wire that is making my amp not work all I would have to do is just run that lead to the postive battery terminal and if it works I know its the rem wire and not the amp?

Just use a small jumper from the main power line on the amp for testing.

YEP the rem wire was the problem. I noticed that I get pretty loud pops when I turn on my car from my sub is this ok or will it hurt my sub? Do I need to move my rca's to the other side of my car or buy stronger ones? What else could cause the popping Ill do some research. Would any switch work? even a light switch or something lol?

Thanks

as far as using a remote wire for your amp, i would just connect it to the red wire on the aftermarket harness, that wire only has voltage when the key is in the on position

for some reason i got a new hu and i connected the two rem to both blue wires on the hu but i get nothin, so i wired it to the red/acc wire like i had my other one and it works fine

check the voltage right at the head unit

if there's any voltage, you could use a relay, and avoid having to manually switch it or having the amps on all the time

and a remote wire is a pretty soft 12v, so even a bad crimp could kill it

and whatever you do, if you're going to use a hard 12v for the remote wire, spend the $3 for an inline fuse holder just incase something happens
