we would also need to consider how are the speakers wired series parallel ?

ohm load are they 1 /2/3/4/8 ohms speakers ?

pretty easy to wire 4 speakers together and keep the correct ohm load

My Alpine HU is 4 volt pre outs runs loud and clear.

The channels are paralleled where split

4 ohms I seem to recall maybe

No doubt replacing all the speakers, wiring and amp when changing out the head unit with modern quality gear would great but what a cost...

Thanks for the advice Guys its really appricated.
im not going to install new amps or speakers,as i dont want to spend that sort of money on this car, so either RCAs will work or not, i will just revert to what i have now

i have ordered the RCA to ISO connetor so will shall see...

every thing comes at a cost just like some people will spend 300 /500 1000 dollars on a head unit but use the factory hardware system ?

a good head unit will play allot more frequencies than a stock unit
stock speakers will have a curtain frequency response

maybe your loud and clear is different to my loud and clear
but there is no need to spend lots of money

most cheap amplifiers and speaker splits are dead cheap cheaper brands ...and they pruduce more power and clearer than a stock system ..also they will play longer at higher listening levels with out going into limp mode or cutting out

Hi guys, right update the new bit of loom has turned up and i was hoping that it was " pre wired" but its not, this is what i have

I guess i need whats in the background of this photo

Hi guys, I had a bit of a play with the stereo this morning, and tried to work out the wiring, do the black wires coming from the RCAs need grounding?

Anyone

If you are referring to the wires with a black trace that go to the Rca plug from the iso connector they will be the audio negatives and from memory are soldered to the shield. The positive wire is connected is to the pin.

Cheers
