Aftermarket radio installation

Postby Roger90 » Tue Dec 11, 2018 8:53 pm

Hi all,
The six speaker factory stereo in my '90 U.S. spec Majestic was sounding pretty crappy and I would like some modern conveniences like CDs, blue tooth and so on.
I began my install this afternoon using my Alpine CDE133BT from an X300 I parted out.
I have a copy of the wiring diagram and had no problem finding the two front door speakers and the right rear door speaker using the AA battery trick.
I can't find the connection/s for the left rear door speaker and the under seat speakers. Am I missing something?
Any advice, direction and instruction?
Thank you all,
Roger

I don’t have an answer to your question an afraid.
But if you can fit your radio without chopping the main wiring harness, it will keep the value of your car.
I have seen so many 40s with chopped of radio harness wiring, and owners coming to me asking for the original plugs back!

I have the original radios if you want one, then it’s plug and play.
Let us know what you decide.

On the post 90 models there are ISO wiring adaptors readily available that makes fitting aftermarket stereos plug and play. But I have not seen one that will fit the plugs for a 90 and earlier models. There were at least 5 different radios fitted across the model years for XJ40. That’s just for the UK spec! Then there were other different units used for other counties too, to confuse things further.

well as a ex electrician and a electronics engineers I made a new connector and put a double connector on the original loom with fly lead and pins into back of old connector insulated with heat shrink cover, so you can have old original radio or new type whenever you want

Ok
Good! That’s the rare way of doing it. Most I have seen cut the original plugs off and discard the connector. Then it’s another issue for the next owner to undertake to put back to original (original being what most owners want).

Hi all,

I kept the original radio and cut the wires with enough length to allow the radio to be spliced back in.
I could find no way to remove the connector from the rear of the radio(!?).
In any case I'm not surprised that the job is turning out to be more work than I wanted, but my car is almost 30 years old.

The two rear under seat subwoofers are completely deteriorated and useless. I did, however, get the right subwoofer to respond
to my battery trick (four out of six respond).

I can't get the left ear door speaker and left rear under seat sub to respond to my battery trick.
I will replace all of the speakers, the rear subs are completely dis-integrated.

I'm installing my Alpine CDE133BT to drive the four door speakers and I'll use an Alpine KTP445U to drive the under seat
subs. There is only switched power to the Jaguar radio (two wires), so I'll run two "hot" wires from the battery to the new radio
and mini amp and probably a new wire to control the power aerial or replace it if I must.
