Speaker sound left channel intermittent

Hi All,

I have a 2009 K1200lt Lux.

I have lately had a issues with my left speaker channel. At low sound levels front and back left and right speakers work perfectly. However, when I increase the volume, at a certain peak, the left speaker channel front and back begins to distort cut in and out like there is a loose connection somewhere and the right channel plays perfectly at high volume levels. When I bring the volume back down then the left channel sound perfect and all four speakers sound great. Does anyone have any suggestions or have experienced this issue before.

Many thanks

Re: Speaker sound left channel intermittent

Mine did the same thing until the rears stopped all together. I've heard these bikes are notorious for the radio amps failing
What I did is sent it out to Baris to have it fixed. His email is [email protected] and his web page is below.
BMW wanted $979 new and with the exchange and shipping I was out for less than half of a new. I got all new more powerful amps and a Bluetooth installed

Wow thanks for you reply. I'll give them a shout on Monday. I take it Baris is aware of this BMW LT radio issue occuring? Did you remove just the CD player or is there more to it ?

General Information
Vehicle Name Radio Repair Amplifiers
Year 2019
Make Becker Harmann
Model Professional 2000 ECE
Garage Image
2019 Becker Harmann Professional 2000 ECE
History The most common problem encountered with the BMW K1200LT radio, is the Integrated Circuit Amplifiers failure that causes one or more speaker to stop functioning, or fading.

The symptoms are:
1- No sound
2- Some sound
3- Loss of some or all speakers
4- Weird noise that is screechy and high pitched

This could happen permanently, or after few seconds.
The number of speakers that goes off is random.

This is fully fixable, and the method consists of taking the original amplifiers off the radio motherboard, and installing my custom 4x35W - 4x40w maxi amplifier module.
Note that the original power is 15-20W, after the repair, you will get 35W-40W. The speakers will handle this without problem.
I stopped selling the kit after going through too many mistakes caused by DIY enthusiastic customers!
I'm weekly fixing a radio since 2012, and I'm pretty comfortable doing a good and fast repair.


Here is the cost of my services: (The currency is USD)

- $185 (Repair) + $20 (Shipping to USA)
- $185 (Repair) + $45 (Shipping to International)

The amplifier is tested ok before it's installed into the radio, each wire is tested after soldering.
The CD player stays in the radio

I also offer (Under condition!)

- New 2018 Bluetooth design (This new module isn't connected to the AUX, Therefore the sound is now clear and powerful). Note a switch has been added on the front of the radio (See picture #11) Cost is $55
- Aux Jack 3.5mm cables for cellphone, Ipod, MP3 device (Note that sound coming from AUX isn't powerful) Cost is $10

The turnaround time is about 2 days.

Feel free to contact me if you have another question.

For the payment, I prefer Paypal, I can send you a Paypal money request if preferred.
The currency is USD only.

Chris

PS: Note that the radio repair at Becker Autosound will cost you $400
