Can anyone tell me the location of the amp in an E39 2002 530d sport ??
Im new to the site and to BMW's. Bought the 530d sport recently and im only getting sound from the right channel. Standard factory fit radio/Tape deck head unit with the factory fitted 6 disc cd changer in the boot.
Im told the amp is NOT in the head unit and should be in the boot behind the cd changer?? However i have checked and cant see it there!! Just the cd changer. Someone suggested the amp may be under one of the front seats.
CAN ANYONE TELL ME WHERE IT IS AND HOW TO GET IT OUT FOR TESTING/REPAIR???
Many thanks in advance.
OK. I have double checked the boot beside the cd changer and the battery and beside the spare wheel and there is no amp to be found anywhere. Just the cd changer on its mounting. I even checked under the seats!! Local auto electrician had a look and was sure the amp should be in the boot beside the cd changer too. But he cant find the amp either. He says the head unit doesnt have an inbuilt amp. He seems to think the amp must be a seperate unit and fitted somewhere other than the boot.
Is it possible the head unit has an inbuilt amp??
Did any of the bmw head units come with built in amps??
Any ideas anyone??
Thanks for the link. Appreciate your time and effort.
I have checked and had it checked by an auto spark.
Defo no bloody amp in my boot!!
Im guessing thats why the head unit/ cd changer only plays through one channel. I wasnt even sure if the radio/cd changer COULD produce any output through the speakers without having any amp attached ??
Be interested to know if you'd made any progress with this as I have EXACTLY the same problem. Not losing sound from any channels (other than from a knackered speaker) but do not have the amp behind the CD changer in the boot. Cannot find it anywhere!!
I went into my local bmw dealer yesterday and asked for some help re. this problem. Very helpful guy at the service centre reception came and checked the car for me. He confirmed the following:
1. No amp fitted in my boot(and no sign of there ever having been one-no wiring running into the boot where it should be and no mounting bracket).
2. No amp anywhere else as the boot location is the only place used(checked the whole damn car anyway).
3. Without an amp connected there would be NO sound output (as i suspected).
4. BMW DID use head units with integrated amps(i was told the amp was always seperate in the boot-NOT SO).
5. Showed me how to remove the head unit and check the din plugs as this is the most likely cause of the fault - loose connections on back of head unit.
I am assured the bmw business head units very rarely fail and they had never heard of one producing the fault i have in this dealer.
Basically there MUST be an amp of some description to produce any output and as the seperate boot unit is not fitted there must be an amp somewhere else. This implies the head unit has the integrated amp as there is NO FECKIN SEPERATE ONE. Unfortunately the guy couldnt confirm this from my registration. He tried on his system but it doesnt tell you which audio system was fitted when the car was built as its an option when the car is ordered by the buyer. We didnt have time to remove the unit but im told the serial number and model number on the head unit will allow the parts people in any dealer (or use REALOEM.COM) to identify exactly which head unit you have fitted and whether or not the amp is integrated.
So to the fix:
we need to remove the head unit and ask a dealer to confirm the amp is integrated in the head unit. Then check all the wiring connections are ok on the back of the head unit (dealer told me there is a little metal clip/bar which fits across the back of the din connectors after they are plugged into there appropriate sockets and fully inserts the connector while securing it). If you still have problems an auto spark is needed to check the unit.
Not tried this yet, but i will update the thread when i do.
Let me know if you get anywhere yourself.
As a final word on this, my head unit was knackered (only one channel).. Tested this by removing it and attaching a 12volt power supply with two speakers attached (found the pinout wiring diagram here..... BMW X5 Radio Module and Amp Information - Xoutpost.com ). Replaced the head unit and we are all good.
Regarding the seperate amp. The head unit is wired at speaker level as are all bmw units (im told) and therefore can be used without a seperate amp. IF your bimmer does have an amp it will DEFINATELY be fitted where you gents suggested, namely the boot beside the cd changer which is behind the left hand side boot panel.
Hope this helps someone else.
