High powered audio systems in a vehicle are capable of generating “Live Concert” high levels of sound pressure. Continued exposure to excessively high volume sound levels may cause hearing loss or damage. Also, operation of a motor vehicle while listening to audio equipment at high 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 recommends listening at lower volume levels while driving.
WIRING CO NNE CTIONS
a. Select a suitable location that is convenient for mounting. is accessible for wiring,and has ample room for air circulation and cooling. b. Use the amplifier as a template to mark the mounting holes. Remove the Amplifier and drill 4 holes. USE EXTREME CAUTION, INSPECT UNDERNEATH SURFACE BEFORE DRILLING. c. Secure the Amplifier using the screws provided.
A. CONNECTING THE POWER (Fig. 1)
CAUTION : AS A PRECAUTION, IT IS ADVISABLE TO DISCONNECT THE VEHICLE’S BATTERY BEFORE MAKING CONNECTION TO THE +12 VOLT SUPPLY WIRING.
50/33/20 mm2 depending from the model( Thicker if planning for additional Amplifiers) wire is recommended for both the power and ground wires. 12 Gauge, for the remote turn-on wire. 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, it is essential that the Amplifier be grounded to a clean, bare, metal surface of the vehicle’s chassis.
NOTE: GROUND WIRE SHOULD NOT BE EXTENDED MORE THAN 3 FT. (1 METER).
(2) +12 Volt(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 measures, 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.
(3) Remote Turn-On Input: To Power Antenna output of Car Stereo This Amplifier is turned “ON” remotely when the vehicle’s stereo is turned “ON”.
NOTE : If your radio does not have a +12 Volt output lead when the radio is turned ON, the “RMT” terminal on the Amplifier can be connected to vehicle’s accessory circuit that is live when the key is “ON”.

PLANNING YOUR SYSTEM
MOUNTING YOUR AMPLIFIER
Before beginning the installation, consider the following: a. If you plan to expand your system by adding other components sometime in the future, ensure adequate space is left, and cooling requirements are met.
b. There has to be pre-amp outputs on your headunit. SPL Dynamics Class D amplifiers has been designed to accept only Low-Level signal source. So there has to be pre-amp outputs on your headunit.
c. Are your components matched? The RMS power rating of your speakers must be equal or greater than the amplifier’s. They also must be 1 - 8 Ohms impedance. (This information is normally printed on the speaker magnet).
d. Consider both the length of your leads, and routing when determining the mounting location. Pre-Amp Input Jacks require a length of high quality shielded male to male RCA patch cord.
The mounting position of your Amplifier will have a great effect on its ability to dissipate the heat generated during normal operation. It has an ample heat sink for heat dissipation, and also designed with a thermal shut-down(for heat protection) circuit, making it reasonably tolerant of mounting variations. Any configuration which allows moving air to be directed over the cooling fins will improve heat dissipation dramatically. DO NOT enclose the amplifier in a small box or cover it so that air cannot flow around fins.
Temperatures in car trunks have been measured as high as 175 F(79.5 C) in the summer time. Since the thermal shut-down point for the Amplifier is 185 F(85 C), it is easy to see that it must be mounted for maximum cooling capability. To achieve maximum advantage of convection air flow in an enclosed trunk, mount the amplifier in a vertical position, on a vertical surface.
Cooling requirements are considerably relaxed when mounting inside the passenger compartment since the driver will not
often allow temperatures to reach a critical 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.
NOTE : Use always low-level input if there is pre-amp outputs in your headunit. Distortion level is considerably lower from pre-amp(Low Level) outputs.
Model : MD - 400.2
B. VARIABLE “LPF” LOW-PASS FILTER MONO (40Hz-180Hz): Low-Pass filter circuitry of SPL Dynamics Class D Amplifiers is always activated because these models are designed only to subwoofer use. Low-Pass filter allows frequencies below (40-180Hz) to be amplified.
2/4CH (50Hz-4KHz): “12/24dB” activates the Low-Pass filter circuitry, thus allowing frequencies below (50Hz-4KHz) to be amplified. You can use this filter as :
• Subwoofer Low-Pass filter
• Full-Active system’s Midbass Low-Pass filter
• Full-Active system’s Midrange Low-Pass filter
For normal full-range frequency speaker configuration, as component system with passive crossover or coaxial speakers, set to “OFF”.

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 length possible. If the cable is too long. make an “S” 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).
This GREEN LED will illuminate when the amplifier is turned “ON”. 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 minimum load impedance of 1 Ohms in single amplifier use or 2 Ohms in two amplifiers bridged configurations. Subjecting to impedances lower than recommended, may constitute to potential damage to the MOSFET power supply. Follow instructions on section “ WIRING CONNECTIONS” for further information.
In order to achieve maximum signal-to-noise performance “LEVEL” control adjusts the signal level from your headunit to match the Amplifier’s sensitivity. IT IS NOT A VOLUME OR POWER CONTROL!!!
To adjust, proceed as follows: a. Set input “LEVEL” control to “MIN”. b. Turn your headunit’s volume to maximum level. If distortion is heard decrease headunit’s volume until the sound is clear. c. Turn the “LEVEL” control toward “MAX” in stages, until the onset of audible distortion is heard. then decrease to level prior to the point of audible distortion
NOTE : Not performing above adjustment procedure and/or simply setting “LEVEL” control at or near “MAX” position, may induce electrical audio noise into the system or break down of the amplifier because driving the amplifier to distortion.

C. MONO: VARIABLE SUBSONIC FILTER (17-50Hz) “ON” activates the Subsonic filter circuitry, thus allowing frequencies above (17-50Hz) to be amplified.
D. 2/4CH: VARIABLE “HPF” HIGH-PASS FILTER (15Hz-600Hz / 150Hz-6KHz) “12/24dB” activates the High-Pass filter circuitry, thus allowing frequencies above (15Hz-600Hz / 150Hz-6KHz) to be amplified. You can use this filter as:
• Subwoofer Subsonic filter
• Coaxial speakers High-Pass filter
• Component system High-Pass filter
• Full-Active 4-way system’s Midbass High-Pass filter
• Full-Active 4-way system’s Midranges High-Pass filter
• Full-Active 3-way system’s Midranges High-Pass filter
• Full-Active system’s Tweeter High-Pass filter
12dB = filter slope 12dB/oct 24dB = filter slope 24dB/oct
NOTE: We recommend to use High-Pass filter always when the amplifier’s channel is not driving subwoofer, because full -range speakers can break down if subwoofer frequencies are played with them.
BANDPASS FILTER S-series amplifier’s LPF and HPF can be used at the same time so they can be used as a bandpass filters. Bandpass Filters can be used for:
• Subwoofer
• Full-Active 4-way system’s Midbass
• Full-Active 4-way system’s Midranges
• Full-Active 3-way system’s Midranges
FULL-ACTIVE SYSTEM In Full-Active 3-way system there is subwoofer(s), midranges and tweeters. 2/4 amplifier channels are needed to drive Full-Active 3-way system. (MD-400.2 / MD-60.4 / MD-200.4)
In Full-Active 4-way system there is subwoofer(s), midbasses, midranges and tweeters. 2/4 amplifier channels are needed to drive Full-Active 4-way system. (MD-400.2 / MD-60.4 / MD-200.4)
E. CONNECTING LOW LEVEL INPUTS (RCA jacks) NOTE: DO NOT use in conjunction with High Level input wires.
