Welcome to the forum, while you are waiting for replies try putting Amplifier in the Search function at the top of the page (there are several interesting threads.. :goodjob:

If nobody with the right info spots the thread after a couple of days, send a query to Syecadelic he may be able to answer you about this better than most... :D

you need a line out converter.

go to google and punch in "rca line out converter" and start reading  :mrgreen:

basically you splice it into one of your speakers and it gives you a rca signal to run an amp.

good luck   :goodjob:

*edit - and welcome :-[

wow thanks for your quick response  :)

i bought this RCA line out converter. Now i´m searching for the wiring diagram so i know where to connect the RCA line converter.

i need to know the rear speakers left and right and i need the remote wire.

Do you know the colors of that wires? and maybe what plug they are in?

Thanks again

Splice the converter in at the rear of the car to one of the rear speakers or both if running more than one amp/converter.

At a guess I would say both wires going to a speaker would be the same color, with the earth having a black tracer.

With the remote wire for your amp maybe you could just run a wire with key power or accessory power so the amp is switched on when the key is on? Or you could back probe the plug on the back of the head unit to see if there is a wire that only has power in it when the head unit is switched on?

I think I know where I can get a wiring diagram from to have a look at tomorrow, will let ya know

Seems like I can't think of the wiring colour that matches 'L' but someone might be able to jog my memory.

Basically they are both 0.85 guage wires and they both use the same colours from the head unit to the rear speakers:

Right Rear


Right Left

The remote wire is a 0.3 guage wire

it would appear to be read and green, as per my pis, i cant guarantee that the back are the same as the front. it would seem unatural tho to have different wiring for front and back, but then we are dealing with a foreign model maker...

Thanks for all your posts guys.

I connected the amp and subs on saturday and its working so well! the car almost bounches :)

I found the plug for the speakers, it was brown and only had the speakers connected. i found out wich speaker was what with a small 1.5V batterí. they make small noise when you connect batterí to them. The wires were Red + and blue - for the both of them. The front had black and white for left and black and yellow for right.

The remote wire was yellow, i found that out with Voltage meter very simple.

thank you all for your help

That is great news... :D :happydance:

You are about as far away (in Iceland) from where one of our favourite long term members (Hemmi) came from in Iceland ... Reykjavik

He is back there on holidays .. I was going to suggest you catch up with him until I looked on the map  :eek:

Skuli is in Neskaupstaður...(far eastern tip)  Reykjavik is far South West
