Hogtunes NCA 450-AA : 4 Channel Amplifier / 4x50 watts (1998 - 2013 - model years) - Manual (Page 2)

Thank‐you for choosing the Hogtunes NCA 450‐AA Amplifier. Since positive
word of mouth is the best way to grow our business, we want your system
to work as well as it should. 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. Reading the manual before starting will make
things pretty easy and help you configure the amp correctly for your system.
If you need extra help, please consider a professional installation by your
local motorcycle dealer.
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: Take the 2 wires off each front speaker by gently pulling one at a
time. If Installing on an Ultra, remove each rear speaker grill by undoing the
4 screws on the front of the grills. Carefully lift up on each speaker and take
the 2 wires off by pulling one at a time from the stock speaker. Put the rear
grills, fasteners, and speakers aside.
Step#5‐ Adjusting the “Fader/No Fader” switch on the amp:
On the side of the amplifier is a "Fader/No Fader" switch. This amplifier gets
its music from the radio via the factory speaker wires. Street Glide, EG
Classic, (and Standards with factory radio) only have factory speaker wires
for the front speakers. Ultra Classics have an “active” fader control in the
radio that allow the rider to control the volume levels between the front and
rear speakers. If you have an Ultra and want the amp to run front and rear
speakers, you will put the switch to the "Fader" position. This will also work
if you have a "non‐Ultra" and have added rear speakers, factory rear speaker
harness and the fader function has been activated by the dealer. In all other
cases, the switch will go to the "No Fader" position. This allows all channels
of the amp to be driven equally with no fader. On a Non Ultra, where there is
no fader function, this is perfect if your adding front speakers, and either
speakers in fairing lowers, or speakers in the saddlebag lids.
