Hi all, i have been looking at upgrading MY12 standard audio, i would like to move up to the setup with the front dash speaker, i currently have the AW93-19C164-CU amp and although i have no dash speaker i thought i saw a wire there whilst i was rooting around, i have been looking at other info/forums and still not 100% which way i can go, i think i need to find the B&W amp because myn is a pre 13 model, is this correct, i am not sure if i can go up to Meridian with my early car, am looking for some direction please, an amp model number would help, i have seen a 16ch one ending in BP and a 12 ending in AR, do i need to find an amp beginning with AW93-19C164-**, the last 2 depend on channels. I am aware of the CCF thing. as i have just fitted the DAB and thought i would do the amp then get them both activated together.
Edit, looking at the wiring it looks like my tweeter is jointed to my mids at SPL130-SPL133, so could have to locate that joint to separate them for the newer amp? diagrm show were connectors are so should be able to sort there if needs be.
also looking further I think I need the AW93 prem 16 yellow amp, do I need to change all the speakers or just the Kevlar ones.
Right most speakers on the way, can i get away with leaving the door sub woofers in, they are the only ones i have not sourced yet, do i need to change them.
Can’t help too much, but there are a few threads with people doing what you’re trying to do. Look for posts by Cambo, he has the most experience with swapping speakers in these cars. IIRC I think the speakers (base vs B&W) were generally interchangeable but if you add more speakers it gets more involved.
The plug above shows green (pos from schem) left and other right (neg from schem)
from the pic above the green seems to go to the neg on the speaker and other to pos
confused here?????
Should i just carry on and ignore the +/- on the speaker????
edit, will do some physical multimeter tests tomorrow, could be by design by the audio guys at Jag. Speakers can work reversed, so long as they all are I think, gets complicated. Wonder if got something to do with the acoustics of the car, small air mass, or if just a **** up by Jaguar or even me.

Also upon first looks here, the plugs are wrong way around D and E
if you follow the diags the the grey plug above is D and the blue is E
but above it show them the other way around
In and working ish, still waiting for parcel shelf the get final 4 speakers in, amp seems to be working including centre channel, figured it may work reading other stuff, although once other speakers in will go get a update done so my head unit recognises the newer amp.
Will post few pics later on were I separated the front door mid/tweet and location to pick centre channel wires up.
Can anyone shed any light on post #6, i know it could maybe sound better/different if i switch polarity, but if they are all reverse then could be by design, small cabin, not sure, i cannot get my hands on a Meridian speaker/wiring diagram for setup to confirm if same with those. Got a speaker phase tester coming tomorrow, see what that says.
Clutching at straws here but could be that if all normal polarity and pushing together, with some beans behind it, it may push the screen out............. i know before your start laughing.
Can't help with the wiring but when I do stereo installs I use a polarity checker on EVERYTHING!
Speakers themselves AND the wring going to the speaker. They are dead cheap at under $10.

And look at this??
Now you can use a phone app to check things? Phone APP Checker
I have found speakers wired wrong out of the box and boy if you want a weak and terrible sounding stereo just hook the speakers up backwards!!

Haha, just got one of those, just doing some tests shortly, just looking for some English instructions, will report back, just seems strange that all the signs are good until you look at the speaker itself, which is clearly marked + -.
Initial test show speakers wrong polarity with the FH-168

Andycots, in regards to the polarity of speakers. If I am remembering things correctly, if you apply a positive voltage to the positive terminal, the speaker should move in the outward direction. A speaker is really just a coil and a magnet. So, from a very simple view, wiring it up either way is not going to change how the speaker moves. BUT!!!!!!! (you knew this was coming) To make the sound correct, you want to make sure that all the speakers are wired the same way (ie, when a positive voltage is applied, all the speakers move in the same direction). To not do this, you end up with one speaker pushing (ie, moving outwards) as the other speaker (the one wired backwards) will suck in. This creates a neutral pressure and therefore no sound. You can play with this a little bit by putting 2 speakers near each other and wire them both up the same way and the speakers will add to each other. But, you get them wired opposite of each other and you will get very little volume out of them, even though they are moving wildly.
Having a speaker wired backwards can have a 3 dB affect on the overall system volume. I know, not that big of a deal. But, you are also going to loose a lot of the range of that speaker from that portion of the car, resulting in a sound that is less than desireable. If you wired say one of the mid ranges backwards, you can make it almost as if the lead singer was not coming out of that corner of the car. Music would sound funny. With this being said, you can also use this concept a little bit to create a faux surround sound. This is way more complex than simply grabbing a bunch of speakers and wiring them up. You can grab a few different manufacturers (I tend to keep it simple and only go with 2, one for the front, one for the rear) and if you can get the right mix, you can make the different instruments appear in different locations of your car. The one I had the best luck in, the drummer was in front of you, a guitarist off to either side of you and the lead singer was behind you. Really freaked people out. Granted, you need to be able to tweaker the power to each corner too to get it really setup.
If you need more sound advice, let me know. I used to do a lot with speakers and if you know how to match them up and apply power properly, you can get some fantastic sound.

Great stuff, yes, all i am doing is upgrading my current X351 standard setup to the B&W one, i have the correct amp and got all the correct B&W speakers, they are all been plugged in to the factory setup, a straight swap. just been doing some more reading up on "phase", don't forget all the speaker in the car are reversed phase and that was or appears to be out of the factory, the only presumption i can make is that the systems in the X351 are designed to be "absolute phase" which to most audiophiles, makes no difference, but does to some people, like i say it must be by design, may be worth swapping them all around just to see, out of interest if there is a difference.
If you look at post #6 closely you can see on the speaker the + - signs, follow the wiring diagram and the plug and can clearly see they are reverse.

Andycots, thinking, they may be doing that because of the distance between the rear shelf and the driver. I am going to geek out for a bit. Doing some calculating, I am going to assume that there is a 3 foot difference between the front speakers to the driver's ear and the rear speakers to the driver's ear. Since the speed of sound is 1125 ft/sec,that would mean that at 750 hz, the phase would be in sync (anything less, it will never be in sync) with that difference. Granted, you raise the frequency to 1500 hz and it would be back out, get it up to 3000, it would be back in. A lot of singers are in the 750 hz range for normal singing. So, who knows. I Think it is more of a mind trick than anything else as you can see that as the frequencies change, you are going to go in and out of sync. Since music is made up of many different frequencies at the same time, you will never be 100% good. Hence why I always kept it simple and put + to +, - to -.
Yes I agree in full Thermo, but seems like JLR have different ideas, I am going to correct all the speaker polarities, would like to see a + meridian drawing to see if they went down same route as B&W.
Well thats all the speakers in now just need someone to activate it all, along with the DAB i fitted, got a tip for replacing parcel shelf was real easy once sorted a plan out, even had no concerns taking it back out because i forgot the grills, right at the back, also was good for a photo opportunity.
Got 3 massive tyraps and joined them together I hooked it around the rear lower brake light, the bit you need to pull down on to line it up and i went straight in
You can just see them in the lower pic, hope it helps some others.
amp speaker upgrade
