7. Gain Control – The input gain control is preset to match the output of most source units. It can
be adjusted to match output levels from a variety of source units.
8. RCA Input Jacks – The industry standard RCA jacks provide an easy connection for signal level
input. They are gold-plated to resist the signal degradation caused by corrosion.
9. High Level Inputs – The high level inputs use a detachable connector terminated with 20 AWG
leads. These inputs should be used if the source unit has only speaker line (high level) outputs
and not RCA outputs.
10. Punch Bass (Models 300SP & 400SP) – Helps correct for acoustical deficiencies in the listening
environment by helping produce full range sound without adding excessive boost.. The Punch
Bass control is a narrow band adjustment at 45Hz variable from 0dB to + 18dB. Connection is
made with a cable using RJ-45 and can be installed under the dash for remote control access.
11. Signal Input Switch – This switch allows the amplifier to be driven with either 2 or 4 pairs of
inputs.
12. RCA Pass-Thru Jacks – The Pass-Thru provides a convenient source for daisy-chaining an
additional amplifier without running an extra set of RCA cables from the front of the vehicle to
the rear amplifier location.

INSTALLATION CONSIDERATIONS
The following is a list of tools needed for installation:
Volt/Ohm Meter
Wire strippers
Wire crimpers
Wire cutters
#2 Phillips screwdriver
Battery post wrench
This section focuses on some of the vehicle considerations for installing your new Amplifier. Pre-
planning your system layout and best wiring routes will save installation time. When deciding on
the layout of your new system, be sure that each component will be easily accessible for making
adjustments.
CAUTION: If you feel unsure about installing this system yourself, have it installed
!
by a qualified technician.
CAUTION: Before installation, disconnect the battery negative (-) terminal to
!
prevent damage to the unit, fire and/or possible injury.
Before beginning any installation, follow these simple rules:
1. Be sure to carefully read and understand the instructions before attempting to install the Unit.
2. For safety, disconnect the negative lead from the battery prior to beginning the installation.
3. For easier assembly, we suggest you run all wires prior to mounting your Source Unit in place.
4. Route all of the RCA cables close together and away from any high current wires.
5. Use high quality connectors for a reliable installation and to minimize signal or power loss.
6. Think before you drill! Be careful not to cut or drill into gas tanks, fuel lines, brake or hydraulic
lines, vacuum lines or electrical wiring when working on any vehicle.
7. Never run wires underneath the vehicle. Running the wires inside the vehicle provides the best
protection.
8. Avoid running wires over or through sharp edges. Use rubber or plastic grommets to protect any
wires routed through metal, especially the firewall.
