Figure 3: Upright Mount on Horizontal Surface Figure 4: Parallel Mount on Vertical Surface The amplifier may be mounted upright on a horizontal surface (see Figure 3) or parallel to a vertical surface (see Figure 4). However, the amplifier should never be mounted upside down (see Figure 5) for the simple reason that the hot air generated by the amplifier would have to go through the unit internally on its natural upward path (i.e., "feedback" into the unit) and would result in increased internal temperature. This would speed up the thermal shut down of the amplifier. Figure 5: Inverted Mount (Not Recommended) Vibration: Constant vibration could eventually cause the amplifier to come off its mount, resulting in stress on wire connections, which, in turn, results in "open" or "short" circuit. For this reason, a location with minimum vibration and a flat surface for secure and firm mounting should be chosen for the amplifier. Moisture: The amplifier should never be exposed to moisture and water. Taking all the above into consideration, the best mounting position for the amplifier would be the floor of the trunk or behind the rear seat back. Once the location of all the components has been determined, plan the best routes for all the necessary wiring, making sure that the wires are easily accessible without dismounting the various components. MOUNTING 1. Place the amplifier at the desired location and use it as a template to determine the exact position of the mounting holes. 2. Mark the mounting holes with a felt pen. 3. Put the amplifier aside. 4. If the mounting surface is carpeted, cut out small circles of the carpet and padding around the four mounting holes to expose the metal underneath. 5. Use a center punch to ensure drilling the exact position for the screws. DO NOT BEGIN DRILLING UNTIL YOU HAVE PUT THE AMPLIFIER ASIDE. USING THE AMPLIFIER AS A DRILLING GUIDE MAY CAUSE IRREPARABLE DAMAGE TO THE AMPLIFIER. 6. Mount the amplifier with the screws provided. COUSTIC.COM 9 Figure 6. Typical System connection Figure 7. Typical Multi-amplifier system BI-AMPLIFICATION A bi-amplified system normally consists of an active crossover and two amplifiers. The active crossover divides the audio frequency spectrum into two ranges: frequencies below the crossover point are directed to the amplifier driving the subwoofer(s), while all frequencies above the crossover point are directed to the amplifier driving the mid-range/tweeters. COUSTIC.COM INSTALLATION continued INPUT CONNECTIONS Connect the RCA input jacks of the player or CD player). If line level output source unit to the Speaker Level input of Figure 8: High/Low Impedance Inputs Note: Connect the black ground wire to the source unit ground only if alternator noise is present. SPEAKER CONNECTIONS Connect the Amplifier to the Speakers. Use heavy gauge speaker wires (e.g. 8 - 10 gauge desirable) for these connections. FOR STEREO MODE Note: We recommend a total speaker load of 2, 4 or 8 ohms per channel 1. Connect the left negative ("–") speaker output of the amplifier to the negative terminal of the left speaker. 2. Connect the left positive ("+") speaker output of the amplifier to the positive terminal of the left speaker. 3. Connect the right negative ("–") speaker output of the amplifier to the negative terminal of the right speaker. 4. Connect the right positive ("+") speaker output of the amplifier to the positive terminal of the right speaker. Figure 9: Stereo Connection FOR BRIDGED (MONO) Note: For bridged mono mode, 1. Connect the left positive ("+") speaker of the speaker. 2. Connect the right negative ("–") speaker of the speaker. 3. Make sure that BOTH RCAs (left/right) are bass response and output will suffer. Figure 10: Bridged Single Woofer Connection CAUTION: ANY DEVIATION FROM THE ABOVE SPEAKER CONNECTION MAY CAUSE SERIOUS DAMAGE TO THE AMPLIFIER AND/OR SPEAKERS. PLEASE DOUBLE CHECK THE CONNECTION BEFORE TURNING THE SYSTEM ON. 11 COUSTIC.COM CONNECTING AMPLIFIER Note: Power cables are as important as battery capacity. Use only high quality power gauge size AWG 8 (AWG 4 for the 401/601SE) or HAVE TOO BIG OF A POWER/GROUND Run the power cable through the interior terminal and connecting the other end to the Be sure not to run the power cable together with the audio cables your audio system. If possible, run audio cables other. Never route these wires underneath the vehicle body. It is also advisable to install a circuit breaker/fuse 18” This would effectively lower the risk of the power cable catching fire should a circuit occur in the audio system. A circuit breaker or fuse with 50% of the main batteries’ amp larger in circuit breaker or fuse value means that you have Fuses on the amplifier DO NOT protect the amplifier, they protect the car. CONNECTING AMPLIFIER GROUND WIRE TO THE VEHICLE Find a good ground spot on the vehicles chassis and remove the paint contact point. Attach the ground wire to that contact point and connect ground wire to the GND...
