This was what started it all.   If you have read the Home page introduction, you  know how this one came about. The power amp upgrade involves removing  and replacing 10-13 components on the main circuit board, depending on  what year bike you have. The main component is a new higher quality,  higher power, and lower distortion Power amp IC.
 

The power amp upgrade will not transform your bike into a rolling  concert hall. After all, it is still a motorcycle with small speakers.  But as my customers have found, the upgrade makes a major improvement in  sound quality. They can now enjoy their music just as much as the ride.  A high quality motorcycle deserves high quality music.  

The amp upgrade really isn't about volume, although there is certainly some of that. It is about clarity. Feedback from customers overwhelmingly states how amazed they are at how much cleaner the audio sounds. And when you have clean undistorted sound, you will find you no longer have to push the volume to its limits.

Note: If you own a 2001 or 2002 model, read the page devoted to these bikes before ordering the amp upgrade. Some bikes from these two years do not need the upgrade.
 

Of course, the electronics are only one part of a great sound system.   The speakers are of equal importance.

 This problem causes  the entire motorcycle to act like a microphone when the Intercom is  on.  Not only does  vibration from everything you touch on the bike get transmitted to  the headset, but fairing vibrations from wind and road noise also gets  transmitted to the headset.   The problem is worse for those who set  their intercom volume to higher levels. 
 

You can test this for yourself to see how bad the problem is.
1. Put your helmet on.
2. Turn ignition to accessory.
3. Turn on Intercom
4. Press the left knob and turn the Intercom volume up to about 15 to exaggerate the problem. 
5. Tap on the radio or anywhere on the top shelter. The sound in the  headsets will sound like you are tapping on the microphone.
 

When this fix is installed, the microphonics will  be completely gone. This is NOT a filter being installed  to mask the  problem.  I identified the design problem and engineered a fix for it. I  actually replace the components that are causing the problem. These  components should never have been installed in a sensitive mike pre-amp  circuit to begin with. 

All 2001-2010 Wings except for the airbag model are eligible for radio repair. All repairs are a simple flat rate. The only exception is for physical damage or if a microprocessor or keyboard membrane has failed. These parts are too expensive to include in the flat rate. (those failures are rare.)

My workbench is equipped to fully test every function on these radios. I have designed a custom test fixture. that tests the display and handlebar controls as well as Driver and Passenger headsets, Aux, CD and CB inputs.

Exceptions

I cannot accept the Airbag models for repair because I can't test them. They have different hookups that require a separate harness and hardware for my test fixture. At this time, I can't justify the cost of building the harness due to the low number of these models on the market.

 For those with 2012 and later bikes, it doesn't appear I will ever be able to handle these products. Now that everything is manufactured in Japan, coupled with the lack of US repair facilities, service information is not available. 

 Note: This fix requires that the CB module in the trunk be sent, not the radio.
 

The GL1800 CB has always had a reputation for poor transmit range.  However, there is really nothing wrong with the design of the Honda CB.  (other than the CB being too expensive.)  The major problem  is that Clarion has the modulation levels set too low.  To make matters worse, some headsets have low output microphones.  Very few GL1800 CB's ever transmit anywhere near 100% modulation. In fact, they barely hit 50% on most bikes.  It doesn't matter how far the CB can transmit if the audio level is too low for anyone to hear it. 
 

Note that if you have the CB feedback  squeal problem, the problem must be repaired before getting the CB re-aligned. This fix will only  aggravate the problem.  I will be posting tips on how to fix the  problem. 

For awhile I could not repair these units because most of the parts are now obsolete. But I was able to find a supplier for the power output transistor and can now accept them for repair again.

I cannot repair the later units that are made by Radio Sound Inc. This company has refused to allow service info to leave their premises. As a result, those units are factory service only.

People have been asking for this for a long time. I will have this upgrade available soon and will post it on the store as soon as testing is done and I have inventory in stock.
