INITIAL TESTING

Conrm that everything is working as intended before nal tuning, tting and reassembly. Since you’ve

already had a Stage 2, 3 or 5 system previously installed, this initial testing is simply addressing the amplifer

and subwoofer added in this installation manual procedure.

STEP 1 – RECONNECT THE BATTERY

First, ensure the battery is fully charged. Using a 10mm socket, then

reconnect the negative terminal of the negative battery cable as indicated.

STEP 2 – CONNECT SOURCE UNIT

Connect the electrical plug and two RCA audio cables to the source unit.

The “FRONT” RCA outputs connect to the high frequency (400.2) amplier.

The green “SUB” RCA outputs connect to the low frequency (400.1)

amplier. Temporarily set housing in place, but do not yet attach mounting

screws. This will allow for any corrections of wiring if needed.

STEP 3 – TURN ON IGNITION / PLAY SOURCE

Turn the ignition key to the ACC position. Play some kind of music from the

source unit to begin with an audio signal (via USB, BT, AM/FM, etc.).

STEP 4 – 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

amplier to perform distortion-free, while also allowing you to ne tune any

bass-heavy music by easily reducing the sub level setting from the source

unit.

STEP 5 - VERIFY AMPLIFIER CONNECTED TO SUB - If the new subwoofer is playing, the new subwoofer

amplier is connected. Conrm settings are correct if something doesn’t sound exactly right. Refer to page

7, 8 and 11 for initial amplier settings during the amplier plate installation. If everything is working and

producing sound, proceed to the next section - Fine Tuning.
