WESTMINSTER P38...
Stereo only plays sound out the right speakers.
Adjusting the Balance or Fade buttons makes no difference.
I’ve pulled plugs out of the back end of Nav unit but no change.
Stereo worked fine when I shut the vehicle off last night.
Any ideas?

DSP, door amps or straight to the speakers? If DSP it could be the amp in the back dying,

He's asking what radio set up you have. Mainly, is it a DSP equipped version? Also do you have the additional speaker on the dash?

Morat, I couldn’t tell you what type of setup it has. There is no speaker in the dash. How do I identify if it has DSP?

When you go through the head unit's audio options, do you have a DSP setting? Assuming it has the stock Alpine head unit it should have shipped with.

Failing that, behind the trim in the load space on the left side, if you have DSP, there will be a single large amplifier. If no amplifier, it either has door amps, or is driving the speakers directly from the head unit - which was only really found on more basic models (including the Bordeaux weirdly).

Yes, sorry. If you have sound options for "Driver" and some others I can't remember but similar to Concert Hall or Live then it's a DSP amp which is intended to process the audio stream and tweak it for various conditions. Big news in 2000... ;)

Sadly they're prone to failure and expensive to replace.

Thanks. She’s not DSP....
I’m going to swap radio heads between two P38s and see if this radio works in the other vehicle and vice versa.... Start with the easy cheap stuff....

Ok I resolved the issue. Kind of...
Radio was indeed DLS. I unplugged the connections in the rear cargo to the NAV unit and found that sound came from all speakers on the right side. By tinkering with the BALANCE button I was able to set the balance to L5 and it was enough to give me a perfect balance of sound.
Not ideal but it beats listening to a stereo that was reminiscent of driving to the beach in my dadsFord Cortina that had one speaker on the rear parcel shelf....
