headache with mk4 sound system upgrading :(

Yes mate, that is wholly incorrect.

The amp will only turn on when told to do so by the headunit, otherwise it would be on the whole time and flatten your battery.
What you have connected at that moment is the necessary earth and permanent 12v supply.

You also need to have connected a 'remote' wire, which is a low voltage trigger signal, sent by the head unit to say "turn on" or "turn off", essentially. If you look at the amplifier there are three cable terminals; 12v perm, earth and remote.

Without a remote signal your amp will not run.

yes i held a multimeter over the positive and negative
i was going by the little light turning on when it powers up?
...which it doesnt (turn on)

and i was told that the amp should power up without being connected to a headunit (incorrect information i guess then?)

thanks for the help

ah ok!
so when my new alpine headunit arrives today and i plug it in then it should all work?
...theoretically 

thanks for your help

Yup.

As well as the thick red power cable running from the amp to the battery there should also be a remote cable - do you have that installed? This is a much narrower gauge of wire than your main power cable, its carrying next to no power or current.

That should, along with the RCA cables, journey up behind your dash and be sat behind your headunit waiting to be connected.

When your new headunit arrives plug in your RCA's connect the remote wire from your amp to the appropriate wire on the head unit loom and you'll be in business chap.

yes mate i installed the rca and remote cables yesterday!
....so yes i will plug it all in later on this afternoon and well fingers crossed

thanks for your help

ok
so i have connected everything up!
however the rmt wire (one that turns the amp on and off)

well i am not sure what to connect it to!

in the picture further up on this thread (now my head unit) the black wire is what i think it should be however it has a socket thingy on the end

anyway i stripped the black rubber coating off to find some wire which enclosed another wire (same gauge as my rmt wire)

so what should i do?

connect it to the small wire inside....the wire enclosing the small wire, both, or do i need to get some adapter socket thingy which i wire onto my rmt wire and then plug into the headunit?

please help
....i am so close it is driving me crazy
cheers

google the make and model of ya head unit, that should also bring up the wireing for it , on my head unit the remote wire is blue and has a tag on it and also all the other wires to let ya know wich 1 is for what purpose.

[wakeboarder15]

ok yeah it works

thanks for your help

one other thing though is thatit doesnt turn off or on when putting my keys in (like my old unit)

now i have the red and yellow swapped over (red to yellow)
however there are 2 reds and one of them is loose...should i connect this to the spare port that the red and yellow have?
so double the two red up basically?

cheers
