AMPLIFIER PREPARATION AND MOUNTING (2018.5 Turbo S & 2019 Models)
Before installing the dual amplier plate with the amplier(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 amplier plate installs. If a factory-optioned amplier was present, this would also have been removed.
NOTE - These instructions assume both ampliers 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 amplier 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
tting of the dual amplier plate. It will not have its nal
reassembly at this step.
STEP 2 – AMPLIFIER MOUNTING
Mount your amplier(s) on the dual amplier plate in
the conguration shown. This conguration is critical to
make sure you can access your ne tune adjustments
for crossover and bass boost.
STEP 3 – TRIAL FITTING THE DUAL AMP PLATE
With the ampliers 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 amplier’s on-
board connectors. Loosely t the remaining two (2)
10mm bolts from the ECU bracket to check the t 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 nal reassembly
until after the system has completed testing.
STEP 4 – REMOVE DUAL AMP PLATE AND FLIP
OVER, REMOVE ECU BRACKET
With the ampliers connected to the wiring harness,
place a towel or blanket over the open hood area.
Remove the rst two (2) 10mm bolts for the amp plate,
remove the plate and ip it over on the towel to avoid
scratching the amplier 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 nal testing and nalize the reassembly of the ECU bracket and
dual amp plate.
