Becker install on a MOST system (with some pictures, etc)..

The antenna and microphone all have their standard locations in the 996.
The antenna goes just under the cover for the alarm LED in the dash.
The mic in its position to thr right of the clocks.
Apologoes if this is obvious, but it took me some time to discover them.
Also, illlumination pulse from the switches.

I knew but someone else looking might not so worth posting up. I've also heard/read the mic doesn't work very well in the OEM location but I'm going to try it as it will be the neatest solution.

I think the lighting in the switches is on the dimmer so I don't want to use that so intend to go from the ashtray light instead.
I thought you might, its all a bit obvious, but took me a few minutes to work out when doing my install.
You are probably right about the mic position. Its been mentioned by people that they can't hear me very well, so better to experiment with some other solutions.

I plan to finish the install off once the speaker adaptor rings I've ordered from the US arrive although I've still to order some speakers to go with them.

Have you got a link for the speaker adapter rings?
 
Eddy - Did yours arrive? I just got a refund from DirectCircuit, saying they were having problems shipping out of the country.
 
Mine didn't arrive either, just waiting for a refund.

I got a tracking number but it didn't track outside of the US.

For the speakers, can you not just run some wire from the HU to the output connector on the M490 like I did for the Bose. It doesn't need to go through the amp to jumper into it. I used IP67 AMP Superseal pins from RS components, crimped with a bit of heat shrink. They fit in to the amp connector nicely.

Have you got a link to those connectors as I can't find them. I've connected the dash speakers directly but need to get the door speakers wired up.

Also is the amp labelled up with the outputs so I can tell what to connect up to for the door speakers?
 
If they are the same as the ones on mine (Harman amp) the speaker connectors are VW parts.

VW Speaker Connectors: 1HO-906-712
Wire: 000-979-129 (this is the yellow wire, and comes with a terminal on each end).

Should be these ones.

The Amp connector isn't labelled but if you're a facelift BOSE system let me know and I'll try and find my wiring diagram and email it to you.

Thanks for the link. I see they are sold in packs of 100, I don't suppose you have 8 spare that you could let me have for a few quid?

Unfortunately mine's not BOSE, it's the facelift upgraded sound package. On the upside the speakers are 4ohm.
 
Just in case anyone with the upgraded sound package looks in here I thought I should post that the RS connectors don't fit. I think I have found something that does and I will post up once I have tried them and can confirm they do.

Seeing as there seems to be a few questions on installing aftermarket kit on a MOST system, here's what I did to install a Becker Cascade.
Usual disclaimers apply, this is not a guide, only a description of how I got round the issue. I'm not an audio installer, copy at your own risk, etc....

I wanted this to be reversible so that if I ever sell the car in the future I can return to standard if need be. For that reason I avoided cutting into existing wiring and just jumpered or used new wires where needed.

I had a quite a few more photos than this but my phone threw a wobbly and lost them before I managed to transfer them to my laptop.

I'll get a few dash pics in the morning and update the thread with them as I fitted a GT3 console delete kit to tidy it up a bit.

Must add that I had a few email conversations with Tino who had also been through this and cleared up a few of my questions.

This is some of what I removed from the car. It's a bit more than most as I removed the Nokia phone holder and also an aftermarket (non-touchscreen) Nav unit that was installed in the lower console and had a DVD unit in the front of the car.

My car was non-PCM so I then removed the head unit, CD changer and Bose amp. The orange cables for the fibre optic link are now redundant.
The factory head unit connector fits Becker anyway so no need for an adaptor but you do need to add a switched 12V feed from the fusebox as there doesn't seem to be anything nearby. Any audio installer should have mini-ISO pins and sockets for this.

I ran decent quality speaker outputs from the head unit through the bulkhead to go to my new amp (Alpine PDX-5). I also ran the 12V wake-up feed wire.
There's a large grommet in the bulkhead that can be accessed from the drivers footwell and comes out behind the battery at the bottom drivers side. You can also see the fuse holder I used for the 12V feed from the battery.

Now, you'll see that my 12V wake-up feed runs alongside my RCA cables. I have a slight hum which I can notice but nobody else seems to hear. I know it's there though so I'm going to try and find an alternative route for the 12V feed.

I already had a pre-drilled hole through the second bulkhead for the previous Nav system so I re-used that for the RCA cables and added some new grommets. I took my battery 12V feed through a seperate, larger, grommet which you can see in the photo below.

And a closer view of the battery feed.

I fit the new amp where the CD changer was located and re-used the CDC mounting bracket also by just bending one side straight to accomodate the Amp.

I didn't want to cut into the existing speaker wires so I used some connectors I had in the garage (they're for IP67 connectors I believe, found at places like RS Components or various car electrical suppliers).
With these I just plugged straight into the output connector from the Bose amp and put heatshrink over each one to avoid any shorting. I jumpered the FL dash and FL door together to make it 4 ohm and done the same for FR. The rears are already 4 ohm.

I didn't use the sub as I removed it to make extra load space for my sons travel cot but you can remove the sub and rewire the speakers inside to be in series which should change it from a 0.5 ohm speaker to a 1 ohm speaker. The PDX-5 should be able to handle that I would imagine.

Finally plugged everything in to the amp, connected up the Head Unit and it works!!!

And with the covers back on although I had to make a little bit of modification to the CDC cover with my Dremel just to get enough space for the wiring to be routed properly.

For the interior, as I mentioned I used the console delete kit. I have heated seats so I extended the wiring for the switches and moved them to the blanks behind the ashtray. All seems to be ok so far.

Looks nice! :thumb: great job!
 
I like the heated seat button placement, more logical really.
 
Refit advice

I am about to fit a pioneer AVIC to my 2003 C4s I have the CDR23 but no Bose, 2 dash, 2 door, and 2 rear speakers no sub, do I need a 4 channel amp and wire the dash and door speakers in series? Or should I use a 5 channel and wire the L & R Door speakers in series to the 5 th channel? What is the best option? Also any recommendations on an amp to use?
