The amplifier’s signal input, female, RCA jacks should be
connected to the source unit’s signal outputs with high-
quality RCA cables. The connectors have been plated in
gold to eliminate the possibility of corrosion that can cause
signal deterioration.
These pass-thru connectors allow you to daisy-chain an
additional Punch amplifier without running an additional
set of RCA cables from the front of the vehicle to the rear
amplifier location. The crossover module in the Pass-Thru
RCA circuit allows the daisy-chained amplifier to be con-
figured independently of the Front and Rear channels for
low pass, high pass or full range operation.
The Pass-Thru signal is derived by summing the Front Left
and Rear Left inputs to create the Left output, and sum-
ming the Front Right and Rear Right input to create the
Right output. This provides constant output regardless of
the source unit fade position.
This section focuses on some of the vehicle consider-
ations for installing your new Punch 4-Channel amplifier.
Checking your battery and current sound system, as well
as pre-planning your system layout and best wiring routes
will save installation time. When deciding how to lay out
your new system, be sure that each component will be
easily accessible for making adjustments.
Before beginning any installation, be sure to follow these
simple rules:
1. Carefully read and understand the instructions before
attempting to install the amplifier.
2. For easier assembly, we suggest you run all wires
prior to mounting your amplifier in place.
3. Use only quality connectors for making connections.
