Set The Ecu And Bracket Back; Trial Fitting The Dual Amp Plate; Remove Dual Amp Plate And Flip Over, Remove Ecu Bracket - MB QUART STAGE 5 Installation Manual

AMPLIFIER PREPARATION AND MOUNTING (2018.5 Turbo S & 2019 Models)
Before installing the dual amplifier plate with the amplifier(s) in position, you must prepare the mounting area
in the vehicle to accept the plate. The area where the ECU bracket was removed and set aside is where the
dual amplifier plate installs. If a factory-optioned amplifier was present, this would also have been removed.
NOTE - These instructions assume both amplifiers and all speakers are present in a full Stage 5 System. If
not all components are present in your system, this makes upgrading much easier.
STEP 1 – SET THE ECU AND BRACKET BACK IN
PLACE*
Set the Dynamics ECU (if present) and ECU mounting
bracket back in its original placement ensuring the wiring
intended for the amplifier harness is routed through the
gap area at the forward section of the bracket. Loosely
reattach only the two (2) 10mm rear bolts (nearest the
dashboard) at this point as shown in Figure 10-4. *It is
only important the ECU bracket is back in place for trial
fitting of the dual amplifier plate. It will not have its final
reassembly at this step.
STEP 2 – AMPLIFIER MOUNTING
Mount your amplifier(s) on the dual amplifier plate in
the configuration shown. This configuration is critical to
make sure you can access your fine tune adjustments
for crossover and bass boost.
STEP 3 – TRIAL FITTING THE DUAL AMP PLATE
With the amplifiers mounted to the plate, place it into
position atop the ECU bracket as shown in Figure 10-6.
Be sure there is free movement of the wiring harness
with enough length to connect to the amplifier's on-
board connectors. Loosely fit the remaining two (2)
10mm bolts from the ECU bracket to check the fit of the
dual amp plate. Connect the power and speaker wiring
to the harness as labeled. Do not zip tie anything at this
point as the amp plate will not have its final reassembly
until after the system has completed testing.
STEP 4 – REMOVE DUAL AMP PLATE AND FLIP
OVER, REMOVE ECU BRACKET
With the amplifiers connected to the wiring harness,
place a towel or blanket over the open hood area.
Remove the first two (2) 10mm bolts for the amp plate,
remove the plate and flip it over on the towel to avoid
scratching the amplifier heatsinks. Next remove the
remaining two (2) 10mm bolts from the ECU mount (if
present) and place the ECU to the side as when initially
disassembled on page 10. This will allow you to continue
working on the other steps of the installation until you're
ready to power up the system, complete final testing and finalize the reassembly of the ECU bracket and
dual amp plate.
