Help Ian
 

Hi I've just fitted a new aftermarket heads unit with a iso adapter kit of eBay and my front speaker aren't working! my question is this I can't seem to find the front speaker connector on the loom behind the head unit!
Have I pushed it out of view?
Or as its Bose do the front speakers run of the rear amp and I'm i looking for a connector not fitted to my car!
Do I need to run fresh speaker wire from the head unit?
Or is is it just that I've purchased a crap adapter kit ( I think so I've already had to sort out its permanent live feed)
Thanks in advance Dave

What did you have before, an RNS-D with Bose?

If so, see the attached connector diagram; Bose would use the 4-channel Line Out connector which includes an "amp on" signal (not sure what it is though).

Note that the 20-pin connector covering CD/Display/LineOut comes in 2 versions. One is a single block, the other is splittable and typically blue/green/yellow.

The permanent live thing is a common issue on aftermarket gear.

But as above.. if you've got Bose, then you'll need to re-jig the speaker connections to feed there.

Yes it's a rns-d and I've seen the pin out sticker on the rns-d that's what makes me think the cable has fallen back into the dash out of sight, I did fit it in the dark with a torch. I'll pull the side panel today and have another look, I think there are 4 multi plugs on the rns-d and I think I unpluged 4! But I've slept since then!! Cheers dave

With Bose all speakers are driven form Bose amp, none directly from radio.

Look at the connector C, looks like you got adapter kit for non Bose cars which only connects line-out for rear speakers and assumes front speakers will be driven directly from unit. You will need adapter kit specifically for Bose for all 4 outputs which connects all pins in C1.

You will probably need a kit that takes signal from speaker level output and connetcs it through resistors to amp as most aftermarket radios use 1.5V line-out but audi system 3.5V so if you run it from line-out it will be very quite.

Looks like this one should do the trick: http://www.ebay.co.uk/itm/Radio-Adap...item19e3871780

Thanks that looks a bit more like it!

Had a bit of a look today and just to check popped the old head unit back in to check the front speakers and the worked fine! looked at my red adapter and the front speaker line outs are missing. my kit is for rear bose only!!
Cheers dave

Problem identified, potentially solved. And no sign of Ian. +++

He is probably busy unleashing the 450 horses under his right foot somewhere +++

harhar... :p

Actually, I've been on the train picking up a new car....

Its 4 rings, but sub 100 bhp (well sub), non quattro and got a handful of faults.

and I love it ;)

Like this maybe? http://www.play.com/Toys/Toys/4-/507...gDetails.html?

Do tell.

Thanks Ainarssems I've also found this kit

Is it better? Will it also solve the lack of volume? Or will I need to run a pre amp?
This may be a stupid question but why don't the RCA's out of the head unit just go to the line in to the Bose amp? Different somehow?
Thanks dave

That is made by Connects2 who are a well-known brand; I'd research what they make as that eBay listing specifically says:
which suggests there's almost certainly a similar unit for RCA outputs. ;)

A question to that eBay seller would be a good start. :cool:

I've fitted the new wiring adapter it's a connects2 CT53-AU04 and now have sound out of all the speakers, the kit is very good and very easy to fit. I've also had a facia plate laser cut, this is the first prototype and needs a little adjustment! I guessed the radius wrong and its not the final material (satin black acrylic) so just a little bit of tweaking to get it fitting perfectly
