DESIGN FEATURES

1.Cast Aluminum Heatsink – The cast aluminum heatsink of the Power amplifier dissipates heat generated by the amplifier's circuitry. The inherent advantage of casting provides a 30% improvement of cooling over conventional extrusion heatsink designs.

2.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.

3.Variable Crossover – The amplifiers have a built-in 24dB/octave Butterworth filter with a crossover point variable from 50Hz to 250Hz. The crossover can be set to Low-Pass (LP) or it can be bypassed by setting it to All Pass (AP).

4.RCA Input Jacks – The industry standard RCA jacks provide an easy connection for signal level input. They are platinum-plated to resist the signal degradation caused by corrosion.

5.LED Power Indicator (Top of unit) – The LED illuminates when the unit is turned on.

6.REM Terminal – This spade terminal is used to remotely turn-on and turn-off the amplifier when +12V DC is applied.

7.Power Terminals – The power and ground connectors on the Power amplifier are platinum- plated and will accommodate up to 8 AWG wire maximizing the input current capability of the amplifier.

8.Punch Bass – The Punch Bass control 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.

9.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.

10.Speaker Terminals – The heavy duty, platinum-plated terminal block connectors (+ and –) will accept wire sizes from 8 AWG to 18 AWG. These platinum-plated connectors are immune to corrosion that can cause signal deterioration.

INSTALLATION

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

Hand held drill w/assorted bits 1/8" diameter heatshrink tubing Assorted connectors

Adequate Length—Red Power Wire Adequate Length—Remote Turn-on Wire Adequate Length—Black Grounding Wire

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.
