INITIAL TESTING
This step is to confirm that everything is working before you put the vehicle back together.
STEP 1 – RECONNECT THE BATTERY
With the audio harness connected to the bus bar, you
can now reconnect the negative terminal of the negative
battery cable as indicated in Figure 19-1.
STEP 2 – TURN ON IGNITION
Turn the ignition key to the ACC position and push the
PWR button on your source unit.
STEP 3a – INITIAL CHECKS (Non-Ride Command)
Confirm connectivity of the system you just installed.
Refer to the full manual for the MBQR-RAD-2 source unit
to use features like Bluetooth® pairing, adjusting treble and bass or working with the EQ. You will need to
set the source unit’s subwoofer low pass crossover and level in this step. With the power “ON” use the list
here to check the system for all of the following:
●
POWER ON
- MB Quart source unit lights up and responds to button presses
●
USB INPUT
(if used) responds when selected.
●
AUX 3.5mm INPUT
(if used) responds when selected.
●
BT MUSIC
- Follow the pairing instructions in your source unit and test a Bluetooth
®
source.
●
AM/FM/WB RADIO
- Unless you have installed an AM/FM antenna, you will only hear static.
●
SUB FREQUENCY and LEVEL SETTING
- In the settings menu, set the source unit’s SUB OUT (Low
Pass) crossover at 100Hz. Next, set the source unit’s SUB OUT level at 35dB for the initial testing. A level
setting of 35dB will allow the recommended gain control settings on the subwoofer amplifier to perform
distortion-free, while also allowing you to fine-tune any bass-heavy music by easily reducing the sub-level
setting from the source unit.
STEP 3b – INITIAL CHECKS (Ride Command-Equipped)
With the Ride Command unit power “ON”, check the system for all of the following:
●
POWER ON
- Ride Command source unit lights up and responds to button presses.
●
USB INPUT
(if used) responds when selected on Ride Command unit.
●
BT MUSIC
- Follow the Ride Command pairing instructions and test a Bluetooth
®
source.
●
AM/FM RADIO
- If using AM/FM within Ride Command, check audio with a strong station.
Step 4 - SPEAKER AND AMPLIFIER CHECKS (all systems)
● CORRECT LEFT/RIGHT BALANCE
- Make sure you are using the controls on the source unit to
confirm“LEFT” is the left-side channel and “RIGHT” is the right-side channel.
If you have installed the
optional rear speaker pods (part# NHT1-120BPR)
, there will be no change on the fader front/rear
speakers as all speakers are on the same two-channel (NA2-400.2RC) amplifier and “FRONT” output.
● AMPLIFIERS
- If the speakers are playing, the amplifiers are on. Confirm settings are correct something
doesn’t sound exactly right. CONFIRM ALL SPEAKERS ARE CONNECTED TO THE CORRECT
AMPLIFIER before making any further adjustments. Refer to page 24 for initial amplifier settings during the
amplifier plate installation.
If everything is working and producing sound, proceed to the next section - Fine Tuning.
