A common one to check is that any amplifier trigger output is present, that has changed between pinouts on different units.
Leading evidence: 'Replace between pinouts' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace between pinouts' (1 discussions).

I used the supplied wiring loom adapter and run a separate accessory power to the new head unit which now powers up.

In my car, that loom uses a common ground across the four speakers (so only uses 5 wires) and most amps that take speaker lever don't like that - so try connecting just one speaker line at the amp?

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hello,
First post on here.
I'm looking for help wiring my 996 (2003) with a Alpine ILX-700.
I've got the old PCM2 out fine. I used the supplied wiring loom adapter and run a separate accessory power to the new head unit which now powers up.
Problem is I get no sound...
Note:
I have the Becker DSP amplifier and PCM2 RDW.
This is the wiring loom adapter I was supplied -

Anyone got ideas of what I'm missing (extra brain cells excluded)
Thanks
Karl
Hi Karl,
The link you have is for an antenna adapter, nothing else. A common one to check is that any amplifier trigger output is present, that has changed between pinouts on different units. I am not sire when the PCM changed to optical (MOST) output. Post up more pinouts and info and I might be able to help.

Sorry that was the wrong link:
https://www.dynamicsounds.co.uk/con...ystem-amplifier-adaptor.html?search=ct53-po01
This is what I was provided.
Mine has an optical arial and two other optical connections. The CD changer is also via optical.
I will go out to the car now and post some pictures.
Thankfully, mine didn't have MOST, so my advice will be limited!
So things to check:
Does the converter need power? Is it getting it? (Does it have an LED or anything?)
Is the amp getting power? That should have a more obvious LED
Have you wired the amp to use speaker level or phono / RCA cables?
If it is doing speaker level, are you using the car's loom to get the signal to the amp in the frunk?
In my car, that loom uses a common ground across the four speakers (so only uses 5 wires) and most amps that take speaker lever don't like that - so try connecting just one speaker line at the amp?
I ended up making up my own speaker cable loom
The amp does the doors and the H/U does the dash & rear panels.
The adapter you have bought bypasses your factory amp (sound provided via the optical feed!)
What you need is one of either:
- adapter to feed optical from your new HU to the Becker DSP
EDIT: see here for the one you want
http://www.connects2.co.uk/Product/ProductItem/CT51-PO04
or
- wiring look to take new HU sound output --> speakers directly.
thought I'd just add to this thread.
I'd like to replace the original PCM with an Alpine ILX700.
Apart from this :

What else do I need for my 996tt 2002 to fit the Alpine?
Also how does the old unit come out?
