Help- Forester speaker wiring

I've bought myself a new head unit (car stereo) for the Forrie. Finding power was easy- but does anyone have a speaker wiring chart which tells you which speaker goes where and which is -ve and which is +ve? Car is an MY04.

how was it when you disconnected it? was there any markings on the old unit?

Speaker and power wires all go through the one connector. The Pioneer unit has individual wires. I found one the internet, but it lists common earths for left and right hand speakers. It's been years since I've installed car radios and I have forgotten too much!

The one I found does not have the same coloured wiring as my car. Back to square 1

are the speaker wires in pairs (figure 8 cable)?

no, unfortunately

Buy yourself an adapter harness. It's well worth the cost and saves the headache of trying to sort wires.

Just dug out the bit of paper from when I first did mine back in 2006. Copied below verbatim. From memory, I think I had to test and trace all these manually, and the first colour is the body colour of the wire, second colour is the colour of the stripe. Pretty sure () this is accurate:

black - negative
blue/brown - positive
yellow/green - accessories on
purple - lights on
white/red - rear left positive
blue/yellow - rear right positive
red/white - rear right negative
white/black - front right negative
blue - front right positive
green - front left negative
brown/white - front left positive
red/black - rear left negative
blue/white - ? *
black/yellow - ?

*This might be power or switch signal to the RF amplifier for the window-mounted antenna, but no guarantees on this (or any of it for that matter!)

Good luck with the install Tony. I certainly prefer the sound of my Clarion over the original deck. https://offroadsubarus.com/showthread.php?t=975

Thanks Simon, that was a great help. Everything I found on the web was wrong, even though it listed speaker wiring for almost every model Subaru by model and year. So, I've got a bit of soldering to do, but at least it will be working this weekend. I'm doing it in such a way that should I sell the car, the original unit will go back in without issue. I ended up getting a Kenwood head unit with blue tooth and USB input. It was brand new but last years model, so I got it a fair bit cheaper.
