Hi all, hope you’re well.

• The car.
  1997 4.6 HSE 100k miles, aftermarket head unit pioneer, HK sound system, aftermarket amplifier interface to connect ISO to LandRover Pink 10 pin.

• The fault.
  No speakers are working on the right hand side of the car. They haven’t since purchased. LHS works fine as expected. HK tweeters, with door cars off and speakers out no HK mentioned on speaker labels, just landrover logo. 3 speakers in driver door, two in rear door.

• What’s been tried.
  New head unit, (originally thought this was the fault) the new one is tested as working.
  New amplifier interface to allow the subwoofer and additional audio devices to work. (Before had a cut iso connector to exclude two orange wires for the 10 pin pink).
  Trims taken apart, wires read resistance with a multimeter from the kick plate (by bonnet latch) to the door speakers, also resistance read from the kick plate to the head unit.
  Looked for an amplifier in the door, none found, then searched rear above CD changer, none found. (My understanding is early has 4X amps in doors, late has 1X in rear of car).

• Additional info.
  So all speakers work, they’ve been tested, wires all seem ok, no corrosion visible at any of the splice locations and the multimeter reads them fine.
  If I rotate the pink 10 pin 180deg, the sound still comes from the LHS despite the fact now the red/blue (RHS) speaker wires are being power sourced.

So is there an amplifier for the RHS somewhere I can’t find?? The white plug connector that splits from main harness to the front door/ rear doors also seems ok?
I’m going bloody crazy over what should’ve been a simple stereo head unit change. I think thats all the information I have. I’d attach a photo but haven’t worked out how to link a source thing yet.

Any help is hugely appreciated. I’m understanding of a cars radio system and speaker layout but this thing seems a different level! Theres like 30 wires going into the door! Things were seriously hefty before CANBUS.

Many thanks, Charlie
