    Yeah - I'm sure they won't cost too much. Just a little confused as to what the RCA jacks are for if not for input. I found a manual online and doesn't mention them at all. Yeah, radio is switched off automatically when you insert a CD.

    Rear speakers only is if I'm playing from my mobile phone via the "Line In" if it can so be called. It's odd.

    I just got a set of Sony car speakers from freecycle. Awesome idea, freecycle is.

    Spode - you thought about wiring up all 4 speakers to just the rear channel? It's sub-optimal, obviously, but it might be your only real option if mp3 is going to be your main form of music.

    You could set up a switch of some kind under/in/around the dash somewhere that switches between the rear channels powering all 4 speakers, and normal operation without too much trouble.

    Hmm. not a bad idea.

    Thing is - it does come through the front channel but it just seems a lot quieter than the read, so I've had to adjust the fade. I wonder if it's something to do with the different speaker sizes or something. In which case - wiring them to the same channel won't help!

    Well, to test that - swap them around and see if the problem persists. Just wire the front speakers to the rear outputs and vice-versa.

    The phono's are line out, for connecting the head unit to a more powerful amp. It sounds like something isn't wired right there, most car speakers are 4 ohms and will give roughly the same SPL. Beware of wiring them in parallel as this will result in a 2 ohm load and a blown up power amp section.

    Can you post the url of the wiring digram, so I can have a look and see what might be happening.

    I wish I had a wiring diagram! They aren't wired in parrallel though - they are going to separate channels.

    I had a feeling they might be a line-out and my signal was merely leaking over - which is why it wasn't being processed for fade/balance etc.

    Spode, there is often a line in on the main plug/s, the one that carries the power and speaker outs. (There may be two of these.)
    I was just warning you about accidently wiring the speakers in parallel, just in case. I would hate you to ruin your new acquisition.

    You should be able to find the line in pins (if any) with a small metal screwdriver/probe thingy. By touching the spare pins, you should get a click through the relevant speaker when the volume is set high. Of course everything needs to be connected and switched on for this to work. (Sorry if that seems obvious) Line in is not always via a phono plug. I hope that helps a bit. :D

    Oooh, interesting. I hadn't thought of that. Well it's a Pioneer DEH-2300RB if you fancy hunting anything out ;)

    Mmm, it looks like there is no line in. I'm sure it would have shown up in the installation manual. the other thing that worried me was the auto CD play switching.
    Oh well, someone may have a decent FM transmitter on Freecycle.
