Amplifier Turn-on lead??

[iam_dominic]

In my amplifier instruction manual it says to connect the turn-on lead to the "power antenna turn-on lead" at the head unit. Any ideas which colour this power antenna wire is?

[AR93NT]

in my experience the remote wire and the antenna wire from the HU have writing on them stating what they are...

am i thinking of the same thing?

[iam_dominic]

i have a blue wire coming from the HU with a tag attached to it saying "System remote control" and theres also a green/red wire thats the "power antenna up/down". which one should i connect the amps turn-on lead to?

[someonestolecc]

Usually the blue one will be to the amp. This will send a current when the HU is on (so your amp will be on the whole time your HU is on).

Typically the power antenna up/down will only send current when the radio is on (thereby switching your antenna to go up when it's needed only).

So use the blue one.

As an interesting point my antenna up/down is always on. I hate that it's stupid.

somoeonestolecc: Thats your headunit, I had a cheap crap pioneer headunit in the car when i got it, it left the antenna up all the time when playing cds etc... i upgraded to a better headunit and now the antenna stays down when not on radio etc

ok im attaching it to the System remote control wire... hopefully it will work and wont blow everything up on me thanks guys for ya help

its only 5volts running through the remote control wire

its only 5volts running through the remote control wire

You sure?

The trick with intergrated decks was always to connect the remote wire to the ciggy lighter, thats 12v.

hmm nope not 100% sure, but i remember testing it on my old PPI amp in my old car and swear that the remote wire coming from the headunit was 5v... could be wrong

[BADHAB|T]

I dont think its 5v.... 12 makes more sense because.....

If you have a Sony or something with 2 remote wires, blue - electric antenna and blue/white - amp remote. I worked on a car yesterday (and have had this problem before) where the second hand Sony tape decks blue wire didnt have any power coming out of it, so I simply used the amp remote. A power aerial works on a 12v power supply.

Also, a Pioneer unit or the like which only have a single blue wire for both electric antenna and amp remote must be 12v to make the electric wire work.....

To prove the electric aerial needs a 12v power supply - if the system remote failed on a Pioneer, you can use the red ACC wire to get the power aerial going.....

I think all that makes sense, if it doesnt, read it again
