Audio problem advice please, Amp or BT switcher maybe?

[steveatesh]

I have a MY2010 Vantage V8 with premium audio.

A couple months ago I picked up some distortion from the passenger door speaker, it appeared to be intermittent, then went away but came back last week. I thought it was the speaker grill until this evening.

Anyway, first sign it was more than that was call on the telephone this evening coming through only the drivers door speaker, this has never happened before the phone has always come through both sides in the past (although last week the phone didn't pair at all and I had to re -pair it with the car )

Anyway, on the driveway I put a CD on and sure enough it was coming mainly through the drivers side. I played with the balance and on full left I could hear the passenger side speakers but not very loud or clear. I then applied fader and I may need to retest it but think (and I stress think) the rear left hand speaker was not as badly affected as the front left hand side speaker.

So I'm thinking it could be an amp problem or the BT switching problem mentioned in this thread :

I also found this thread which may or may not be helpful with my problem as symptoms are not quite the same:

So my questions:

How best can I test the audio system or what can I do to help identify the offending part, other than paying £120 + VAT per hour to a dealer?

If it's the BT module is there an upgrade available that alllows an iphone to be connected and stream music (sure I read that recently!) if so about how much does this cost?

If it's an Amp problem, where is the Amp in the car and is a swap over a DIY fix at all?

Any ideas how much a new amp would be if I need one?

Any ideas how much a replacement like for like BT module will be if it's that?

Anybody know if James from Trackaphone is still around these parts?

Cheers all, not sure if this is a crap end to 2016 or a crap start to 2017!

Have a good new year everybody

Hey Steve

James offers a BT module that is an improvement on the original. It's a straight swap and easy to fit
The wiring bypass harness was purely for the purpose of diagnosis.
The replacement relay has been in ever since 2012 and I've not had a repeat of the issue.

The relay isn't expensive and unless you're feeling especially tight on funds I wouldn't bother getting the trial harness as the symptoms sound exactly right for the relay.

Try pinging James Hawkes Reed an email and he'll be in touch telling you how to get the part.
It's a 30 minute job to install with some torx bits to get the floor plate out.

That's great thanks Peter
