That is very interesting on the disco amp. I wonder that Marty did not go that route? Maybe send him a PM and ask?
If you really get frustrated by the rewiring process, I do seem to have 4 spare tested working DSP amps here that
I have collected from breakers over the years.......I also have the aforementioned disco amp on the shelf.
Of course, these may be considered to be "Geographically undesirable" but I don't need that many spares.
You're such a hoarder :) That's a really nice little stash, though!

Does it still have the part number on it or has that been taken off?
No, it looks to have been removed. All the screws are marked and there's a Warranty Seal on it. I don't think he wants me peeking :) which is fair enough.
Oh OK. Well I certainly haven't added any wiring, this was meant to be plug and play. Curiouser and Curiouser.
Great info!
I wonder if our chap is moving the connections around in a disco2 amp to match the P38 pinout?

The P38 system only supplies left and right channels to the amp and signal is split inside the amp to feed the rear speakers. When installing Marty's alternative, you have to run additional wires from the rear outputs on the head unit (which are there just not used) to feed the amps that drive the rear speakers. Without a full circuit diagram I don't know if you would be able to run the additional wires to the Disco amp and make the rears work.
If you don't have the DSP features, it sounds almost as if they have done a similar job to Marty (who used 4 door amps from earlier pre-DSP cars) or something similar to what I have all the bits to put together but just haven't got around to it (see https://rangerovers.pub/topic/8-info-p38-alpine-dsp-amp-connections-and-wiring?page=1#pid30814) rather than supplying a DSP amp.
Yes, that's all true - but it remains to be seen if this is a disco amp or not. The claim is that it's another HK amp that has been modified to work with the P38. If that is the case, it could still be a disco amp I guess, but if it's possible to modify one to work with the P38 without the door amp shenanigens I'm all for it!
And much WhatsApping later, the amp is going back to be inspected. It should drive the rears and subs but it doesn't. My old amp, however, is doing just fine after some.. <cough>contactcleaner<cough> was used to do some serious maintenance. Ah well.
I'm still interested to know if there is a DSP alternative available to us as I'm sure I'll need one sooner or later.
MOT day. She went through, some advisories. The only worrying one is a front balljoint with play, which is a shame as I had those done soon after I got her... It's been a while!
That's the thing. The page promises everything will work apart from the DSP "concert hall" type features. If it's just a Disco amp then I'm unimpressed as they claimed that they modify an amp to work fully with a P38.
I have emailed them.
Hmmm front speakers only. I shall make enquiries.
OK, laziness.
Well that was a lot of digging to get to the amp! Anyway, it's disconnected now, and the ticking/thumping has stopped.
So that's good.
I guess it's time to pay up for the replacement, a mere £250 if you please. But, it's better than rewiring the whole car IMO. I realise that Marty and others have come up with replacement door amps etc, but I'm going to go with the pay, plug and play option due to <s>:laziness</s>: err wanting to keep it as original as possible.
She does.
Arse. I think I'm going to disconnect the battery, and physically pull the DSP.
If the fault leaves with the DSP then I'll be looking for alternatives.
Thanks! as ever...
While we're at it... does this look like a good idea? I don't ever use the DSP presets anyway: https://carphonics.co.uk/shop/shop-by-car/range-rover/range-rover-p38-1994-2002/land-range-rover-p38-harman-kardon-amplifier-replacement-xqk100340/
This is incredibly cool! Nice work indeed :)
The Duchess has decided to start making a banging noise. Not a mechanical one, but when she's parked the speakers thump loudly, even with the key out. This is has got so bad I can hear it in the house and it has flattened the battery!
What is the remedy? In the meantime, knowing which fuse(s) to pull would be really helpful!!
Does that work on a 97? I thought it was only the later ones...

Someone needs to get one of Psidoc's chipped unlocked ECU units and go plug it in and drive it off.
About a 5 minute job!
I would love to see the look on the seller's face!
haha that would be ideal!
I'd probably take a set of EAS emergency valves and a couple of bags just in case.

Isn't that the point? :)
Does anyone fancy a go at this? It seems that for the price of fitting a new driver's door handle you could have another P38 for £1
(plus the cost of fixing all the other bits they're not telling you about lol)

However, once you get it and start using it, you'll be putting the Elgrand up for sale.
Which one? LOL
