12v on remote cable but amplifier not turning on (checked everything)

[Hylcod]

Dear Caraudio,

Today I was trying to install my subwoofer again as I had it out of my car for a some 5 months.

It always worked perfectly fine and I can't get the remote cable/slot to get it to work BUT there is 12v on the cable, I'll explain how.

Because I had it worked before all my cables were still in my trunk waiting to be connected.

I have everything connected but it's simply not turning on EXCEPT when I use a paperclip between the 12v slot on my amplifier and the REM (remote) slot, then the light is burning and.. there's sound.

When I grab my meter I can see there's 12v on the remote cable but when I put it in the slot on my subwoofer it's just not turning the amplifier on.

Is this some kind of magic that I don't know of?

Any help would be welcome and greatly appreciated because I really don't know what's going on, what can be the problem?

It seems that the wire is not making good contact inside the remote terminal.

Thank you for your reply, much appreciated.

The wire is definitely making contact in the terminal, that's not the problem.

Is it possible something's broking inside the amplifier?

The only thing the remote does is give the amplifier an electric signal that it must get to work right?

Run a new remote wire, it's not a difficult task

But.. There is 12v on the cable so it gets electricity, why should I replace it then?

If you can give me a liget reason I'll try tomorrow //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Well, if it works when you jump from the positive to the remote but not when your remote wire is actually plugged in it has to be something with the remote wire. That is the ONLY thing possibly wrong here. Where are you measuring from? If you're measuring between the remote and positive of your amp then the remote wire is grounding out.

please post pics of wiring

make sure main pwr cable for the amp is connected, and that there is a fuse in the fuse holder

We had a similar issue today. The remote wire wasn't providing enough current to turn on the amp... Sounds crazy, but the DMM measured 12v output from the HU's remote output but it wouldn't turn on the amp. We jumped it to the positive wire and it worked fine

OP try wiring in a relay with your HU's remote as the turn on signal.

He just said it worked fine if the remote was jumped to the power, and the DMM read 12v on the remote wire.

Awesome, thank you for your reply, for a while it seemed like I was the only one on this plant with this problem //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

So what was exactly what you did? My history in car audio only consists of installing audio in my own car so a step by step explanation without too many abbreviations would be great.

Thank you in advance!

run a wire from the remote terminal to the front of the car. same with the positive terminal on the amp. then put a relay switch between the two wires. their like 2 - 3 bucks at your local auto shop

that is irrelevant to this post...

^^^ this is correct^^^ grounding out or not getting enough power either way replacing the remote should fix it!!!

Using Relays To Wiring Off Road Lights And Accessories Shows you basic schematic for relays. a spst or spdt relay will work for this.

85-gnd

86-remote output from deck

87-12v

30-amp remote input.

There's 11,35V on the remote, I guess that's not enough.

How do I improve the voltage or is there another way around except for putting a relay in the front of the car between the 12v input and the remote input.

I'm not a big technician but if there are some handy things I can try it would be nice!
