Thank-you for choosing the Hogtunes FLSK 225-AA Fairing Lower Speaker Kit with 
Amplifier! Since positive word of mouth is the best way to grow our business, we 
want your new system to work as well as it was designed to.  If you have any  
questions or concerns, we are here to help. Email [email protected], or call us  
during regular business hours (EST) at  (705)-719-6361. If you still need help, please          
consider a professional installation by your motorcycle dealer.  

 

Please read these important points before getting started! 

 

*  In its most common configuration, the supplied amplifier will power the lower    

speakers, and your radios built in amplifier will power the front speakers which 
is how this manual is written. If you are installing this kit on a bike with an  

  existing amp, CVO® Ultra Classic, or CVO® Road Glide Ultra, please email 

[email protected] for more Information. There are too many ways to make 
this kit work and have them all in this manual, so we will send install instructions 
specific to what you are doing. 

 

* FLSK 225-AA works on 1998-2013 bikes with a factory radio and Ultra Classic style 

fairing lowers. This kit WILL NOT work if you have a 1998-2009 Road Glide  
with the  FLTR Road Glide specific lowers offered in those years.  

 

* This kit cannot be used on 2011-2013 CVO® Street Glide or Road Glide Models that 

came with factory amplifiers. 

 

* For 1998-2013 Street Glide/EG Classic/Ultra Models, if you have something on top 

of the radio already, and the amp in this kit will not fit, you can use Hogtunes 
2CHSP (Drag Specialties Part # 4405-0234) mounting plate to relocate the amp 
between the  radio and brake side speaker. 

 

*  For ALL Road Glide Models with ULTRA style lowers, Hogtunes RG Adaptor kit 

(Drag Specialties Part # 4405-0096)  is required to install the amplifier properly!

 

 

Getting Started: 

 

Step #1: Remove the seat, and both wires (+ and -) from the battery. 

 

Step #2: Remove the  outer fairing/headlamp assembly. Refer to a service manual if 
you need help with this. Note: A towel on the front fender can help prevent 
scratches or “dings” from dropped tools or fasteners etc.  

 

Step #3:  On Street Glide/Ultra Models, the amplifier gets mounted to the top of 
the factory radio using the supplied “hook and loop” adhesive, and must sit so you 
can read the text on top of the amplifier as shown in Diagram 1.1 .The amp needs to 
mount as far back on the radio as possible so the fairing can go back on. The           
minimum distance from the back of the radio to the most forward edge of the        
amplifier is 5/8” (15mm). On pre-2006 model bikes, it is a tight fit, but will go. 2006 
and newer Ultras have the CB Radio mounted on top of the radio. The hook and 
loop adhesive is strong enough to have half the amp sitting on top of the CB radio 
as shown in Diagram 1.2. Model 2006 and newer non-Ultras have a “bump” on top 
of the radio that runs down the center of the radio.
