Summary

Introduction

Before Installation

Guidance on correct installation, including safety precautions and connection tips for optimal performance and longevity.

Audio Input

RCA Input Connections

Connect to radio/player outputs using shielded RCA cables for 4 independent channels to prevent unwanted noise.

High Input Connections

Use when radio lacks RCA outputs; connects to amplified output signals via REM for remote activation.

Audio Controls

Level Control

Adjusts signal level sent to speakers for equalizing music volume playback.

Variable Crossover

Allows adjustment of crossover cut-off range from 50Hz to 2.3KHz, working with crossover switches.

Crossover Switches

Two selection switches (HPF, FLAT, LPF) control frequency cut-off for two channels at a time.

Cooler Operation

Automatic, variable operation optimizing amplifier ventilation. Requires ventilated installation.

Speakers Output

Speakers Connector

Amplified audio outputs for speaker connection. Check polarity and minimum impedance before installation.

Power Supply

Positive Connector

Connect to the battery's positive terminal with a 6 AWG cable and a 40A fuse, placed close to the battery.

Remote Activation Connector (REM)

Automatic activation with radio/player. Connect to the REMOTE output via a minimum 18 AWG cable.

Negative Connector

Connect to the negative battery terminal using a minimum 6 AWG cable.

LED Indicator

Power Indicator (Blue Light)

Indicates the amplifier is operating when lit.

Protection Indicator (Red Light)

Indicates faults and protection mode. Check protection table for cause and restart amplifier.

Smart Protection System

Fault Diagnostics and Solutions

Details LED flash patterns for faults like short circuit, overheating, and voltage issues, with corresponding solutions.

Installation Guide

Cable and Fuse Specifications

Specifies cable sizes (6 AWG, 18 AWG, 13 AWG) and fuse (40A) for proper installation.

Installation Precautions

Mandatory use of fuse/circuit breaker close to the battery for protection against short circuits and overloads.

High Input Diagram

High Input Wiring

Diagram showing connections for HIGH INPUT using blue and gray wires for CH1-CH4.

Speakers Installation
