INTRODUCTION
Thank you for choosing the Hogtunes NCA-70.2 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.
All the required harnesses are included for powering front speakers, lowers speak
-
ers, or rear speakers. Please note that you WILL have left over harnesses when
done! Do not cut any wires—follow the instructions. Wires left in the bike that are
not currently used will be required if you want to expand your system later on.
The NCA 70.2 is rated for 70 watts per channel using 2 ohm speakers, at
14.4volts at 1% Total Harmonic Distortion (THD). Although this amplifier makes its
highest power with 2 ohm speakers, if Hogtunes 5.75 ohm speakers, or 4 ohm
car speakers are used, there will still be a noticeable improvement in volume and
sound quality.
If you are not using Hogtunes speakers, chances are the speaker connectors are
not the same as stock. If you need to change connectors, please note that on all
Hogtunes products, the smaller connector (black wire) is positive (+).
If you are replacing a Hogtunes USA 24.2 you can use the existing 24.2 power
harness as long as you change the fuse at the battery to a 15 amp. Locate and cut
the “zip tie” that holds the 24.2 power and main audio in/out plug together.
Remove the 24.2 audio in/out harness and continue with the NCA 70.2
