Apologies for the long post but I hope this can collate some common questions with some definitive answers
So I've just had an Alpine iDA-X100 installed with the Alpine KCE-350BT Bluetooth phone kit and I have a few niggling problems that other members seem to have had before (and apparently fixed).
I've browsed/searched these forums and wondered if someone could help me clarify a few things (and hopefully help a few others in the future!) so that I can get on with fixing them this weekend...
My car is a rear amped only 2004 Audi A4 Avant.....
So the first common thing is rear speaker whine... from what I've read there are a couple of things I could possibly do to fix this...
If I can utilise the sub (I know it's not the greatest) then I'd like to as currently the volume of the rears and bass is really low and worse than it was before (2x20w from the rear amp for the rears and sub compared to the 2x50w from the new HU for the fronts I assume is the problem)
- Renew / Improve the earthing...
- What earth needs improving? The fuse box? The rear amp? The head unit?
- With what cable and connector? (green/yellow earth cable but what gauge) and to where on the car?
- Or ..... Rewire the rear speakers to directly use the new head unit and bypass the amp...
- Should I run new wires from the headunit adaptor to each speaker (there's two in each rear door) and use what cable?
- How do I split that single wire / signal between the speakers or is it one connection that feeds both in one door?
- How is the sub/amp then powered/fed?
- Can I avoid rewiring from the headunit and hook straight into the exisiting amp/speaker cabling (as shown from this AndyMac picture in this thread: Rear Speakers worth the hassle? ) , again if I do that what happens to the amp/sub?
The second problem is the dimming of the headunit doesn't work... is this something that's easy to fix? I've read about running a new cable from a certain fuse but can't find out much info about which fuse, and what sort of cable.. anyone help / links to advice would be great?
To top it all off the bluetooth bit isn't quite working
I can pair my phone with the Alpine Bluetooth adaptor fine, and it stays paired, but when I click the "Phone" button on the HU it says "No Unit"... I've been through the menus setting Int Mute to Off then gone to Bluetooth menu and set that to "Adaptor" but still the same... I can pair but the HU doesn't see the box.
I'm gonna take the HU out at the weekend so hopefully it's just a cabling issue but I have a feeling (like with all these things ) it's going to be more complicated that that!
Can someone please help (and sorry for such a long first thread!)
