INSTALLATION  

MANUAL

Thank you for choosing the Hogtunes  

NCA 40.4 Amplifier for your bike.  

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]  

Tel:  705-719-6361

A video version of this manual is available at 

www.hogtunes.com.

  

If you still need assistance, please  

consider a professional installation by  

your motorcycle dealer.

IMPORTANT: 

The NCA-40.4 makes its best power when  

powering 2 ohm speakers. Running higher impedance  

speakers (eg, 3,4,6, or 8 ohm) will reduce the amplifier’s power output! 

The NCA-40.4 amplifier cannot be used if any external amplifier is 

already on the bike. 

This includes CVO Models with the factory amplifier 

under the tour-pak!!

 This kit will work on CVO models if the factory  

amplifier and its wiring have been removed.
