It’s versatility enables compatibility with optional Equalizers, Frequency Dividing Network Crossovers, and other audio processors in a customized system. The Multi-Mode bridging capabilities allow flexibility in hosting several different speaker configurations. To achieve optimum performance. it is highly recommended that you read this Owners Manual defore beginning installation, FEATURES * THERMAL / SHORT / OVER LOAD PROTECTION * PEARL SILVER FINISH * 2 OHM STEREO / 4 ORM MONO * PW.M MOSFET POWER SUPPLY * POWER & DISTRESS INDICATOR * SELECTABLE X-OVER HPF / FULL / LPF * 18 dB.

Also, operation of a mater vehicle while listening to audio equipment at nigh volume levels may impair your ability to hear external sounds such as; horns, warning signals, or emergency vehicles, thus constituting to a potential traffic hazard. In the interest of safety, Consumer Electronics recommenas listening at lower vilume levels while driving. PLANNING YOUR SYSTEM Before beginning he installation, consider tne following: a. If you plan to expand your system by adc ag other components somrtime in the future, ensure adequate space is left, ond cooling requiremenis are met. o. Should you use high or low inputs? Your Amplifier has been designed to accept either High-Level (speaker outputs from your TOCdIO) or Low-Level (Pre-Amp outputs from your radio) signal source. If your radio/source is equipped with Pre-Amp outputs, it is possible to utilize them to drive the Amplifier and connecting (Amplifien to the 2 rear speakers. Then, use the builf-in power of your radio to drive the 2 front speakers. NOTE: DISTORTION LEVEL IS CONSIDERABLY LOWER FROM PRE-AMP (LOW LEVEL) OUTPUTS. THAN SPEAKER (HIGH LEVEL) CUTPUTS. С. Are your components matched? The peak power rating of your speakers must be equal or greater than the Amplifier’s. They also must be 2-8 Ohms limpedance (This information os normally printed on the speaker magnet). а. Consider both the length of your leads, and routing when determining the mounting location, Pre-Amp input Jacks requir a length of high auality shielded male fo male RCA patch cord. MOUNTING YOUR AMPLIFIER [ne mounting position of your Amplifier will have a great effect on its ability fo dissipate the heat generated during normal operation. If has ample heat sink for heat dissipation, and also designed with a thermal shut-down (for heat protection) circuit, making air to be directed over the cooling fins will improve heat dissipation dramatically. DO NOT enclose the amplifier in a small box of cover it so that alr cannot flow around fins. Temperatures in car trunks have been measured as high ds 175'F(B0’c) in the summer fime. since the thermal shut-down point for the Amplifier Is 185’F(85’c) it is easy to see that И must be mounted for maximum cooling capability. To achieve maximum advantage of convection als flow In an enclosed trunk, mount the amplifier in a vertical position, on a vertical surface. Cooling requirements are considerably relaxed when mounting inside "ne passenger compariment since the driver will not aften allow temperatures to reach a crifical point. Floor mounting under the seat is usually satisfactory as long as there Is at least 1 inch(2cm) above the Amplifier’s fins for ventilation. a. Select о suitable location that is convenient for mounting, is accessible for wiring, and has ample room for air circulation and cooling. о. Use the amplifier as a template to mark the Mounting holes. Remove the Amplifier and drill 4 noles. use extreme caution, inspect underneath surface before drilling. с. Secure the Amplifier using the screws provided. -3- WIRING CONNECTIONS | | A. CONNECTING THE POWER (Fig. 1) CAUTION: AS A PRECAUTION.

Both types are available at most Mobile Audio Dealers or Installation Shops. (1) GROUND: To Vehicle Chassis To avoid unwanted ignition noise caused by ground loops, if is essential that the Amplifier be grounded to a clean, bare, metal surface of the vehicles chassis. NOTE: GROUND WIRE SHOULD NOT BE EXTENDED MORE THAN 3 FT.(1 METER). (2) +12Volt(Fused) Constant Power: To Battery (+) Due to the power requirements of the Amplifier, this connection should be made directly to the positive (+) terminal of battery. For safety measure, install an in-line Fuse Holder (not included) as close to the battery positive (+) terminal as possible with an ampere rating: not to exceed total value of fuses in Amp.

CONNECTING LOW LEVEL INPUTS (RCA Jacks) NOTE: DO NOT USE IN CONJUNCTION WITH HIGH LEVEL INPUT WIRES. Wire routing is CRITICAL for NOISE FREE PERFORMANCE. Observe the following: 1. Always use high quality RCA type shielded cables. 2. Always use the shortest lenght possible, If the cable is too long, make ап “5” type loop (not a coiled loop) in the center of the cable to take up any excess. 3. Never cut the shielded cable and re-splice it. 4, Never route any Amplifier input cables near or parallel to speaker outputs, high energy ignition wires, or near computer controlled ignition circuit units Computer units may be found behind or under the dash panel in late model cars). POWER INDICATOR LED This METER LAMP will illuminate when the amplifier is turned “ОМ”, If it fails to illuminate, check the power connections to the Amplifier and fuses. PROTECTION CIRCUIT Should the Amplifier be “SHORT CIRCUITED” overloaded or overheated, the protect circuit will “SHUT-DOWN” the Amplifier. CAUTION THIS AMPLIFIER IS DESIGNED TO OPERATE WITH A MINIMUMLOAD IMPEDANCE OF 2 OHMS IN STEREO, OR 4 OHMS IN MONO BRIDGED, MULTI-MODE) CONFIGURATION. SUBJECTING TO IMPEDANCE"S LOWER THAN RECOMMENDED, MAY CONSTITUTE TO POTENTIAL DAMAGE TO THE MOSFET POWER SUPPLY. FOLLOW INSTRUCTIONS ON SECTION. “WIRING CONNECTIONS” FOR FURTHER INFORMATION. INPUT SENSITIVITY (LEVEL) CONTROL (Fig.3) — In order to achieve maximum signal-to -noise performance, this control adjusts the signal level from your Car Stereo/Source, to match the Amplifier’s sensitivity. №15 NOT a volume control. To adjust, proceed as follows: a. Sef INPUT LEVEL Control at mid-point. b. Listen for audible distortion as you increase the Car Stereo VOLUME control. If none is heard, turn the adjustment level control toward to “MAX” in stages, until fhe onset of audible distortion is heard, then decrease to “MIN” level prior to the immediate point of audible distortion. с. If distortion is immediately heard, turn control fo “MIN” until fhe sound is clear, NOTE: NOT PERFORMING ABOVE ADJUSTMENT PROCEDURE AND/OR SIMPLY SETTING THIS CONTROL AT OR NEAR “MAX” POSITION, MAY INDUCE ELECTRICAL AUDIO NOISE INTO THE SYSTEM.

Frequently asked questions
The amplifier accepts both high-level (speaker outputs from your radio) and low-level (pre-amp outputs from your radio) signal sources.
Proper mounting is crucial for heat dissipation. Mounting vertically on a vertical surface in an enclosed trunk is best. Inside the passenger compartment, allow at least 1 inch (2cm) above the fins for ventilation.
The protection lamp indicates a short circuit, overload, or overheating. Turn the radio down and investigate the cause.
Start at the midpoint, increase volume, and adjust the input level control until you hear distortion, then decrease slightly until the sound is clear.
