SOURCE: bad infinity amplifier

I know a few local stereo shops in my area (Oregon) that also do stereo repair. You might call around.

Your other option is to find out the exact model number of the amp and search eBay. When I searched, I found several OEM Infinity amps for sale, but of all different p/n's.

SOURCE: the fuse from the amp to the battery keeps burning

maybe it cannot accomodate too much power running on it...too much current, try another fuse with higher ampere rates

No sound output in 2000 BMW 328i 4dr Sedan but radio functions properly?

Hi Toxey.

Does your trunk amplifier got power.
basically amp need remote power input it is coming from your radio.
please check when you turn on the radio remote power must turn on.
if no it is radio problem or wire is damaged itself.
please check the outputs,speakers with multimeter or single 1.5v cell.
if power is ok.and the remote on signal is ok your device still not working , it is the problem with power amplifier unit.

please check and let us know the status.

Sound goes off to a screeching noise

The sound board is usually part of the main logic board that contains logic, sound processor/amplifiers, tuner, source selctors. Not cheap.
But you should try hooking up a set of powered PC speakers to the Audio line out RCA (Red and White) jacks on the back of the TV to see if you get the sound OK there first, if you do then the power amps that drive the speakers may be bad or it may not be getting the DC voltage feeding it. If it works with RCA jacks, then just keep on using it that way, you may want to set the audio line out to be 'VARIABLE' in the sound set up so you can use the TV remote to control how loud the audio signal feeding the powered PC speakers to be.

I need a schematic for my HK amplifier

Hi all,

Just thought I’d share my experience, I have a 04 cooper with the HK. The radio was still working but the HK settings were lost in the head unit and there was no sound coming out of the speakers so I concluded it was the amp.

I wrote to the Mini UK Customer Services manager, Simon Anderson (, citing I believed the problem was inherent and that it should be replaced for free. He denied this and asked for me to take it to my dealer and once diagnosed ask for a goodwill gesture towards fixing it. I did, they diagnosed that it was the Amp and said that would be 700 quid to fix (160 diagnosis fee, 410 for the amp and 90 for fitting plus VAT). I then asked for goodwill and, after fighting to not to have to pay the diagnosis fee because I approached Simon knowing what the problem was, got it for 160 inc vat which was 20% of the price of the amp plus half an hour fitting. I also had to contact their customer service department a bunch because getting through to Simon direct was challenging. The BMW head office number is 01344 426565, ask for him and they will put you through. FYI the goodwill was, in part I was told, based on the fact that I’d had a ‘real’ bmw dealer service my car.

It still annoys me that I had to pay anything as there clearly is a problem but c’est la vie. If anyone has managed to get this for free from BMW I’d be interested to know.

Good luck

BMW BM54 amplifier.Has a output fault

This is generally caused by nothing more than dry solder joints. Adding more solder to the pcb 'attachments' usually works. Certainly a first step!
