Page 4: Safety Precautions
AFETY PRECAUTIONS Fuse amplifiers power wire at the battery. Be sure to fuse the power wire within 12” of the car's battery. This will protect the car's battery in case of a short circuit between the power amplifier and battery. THIS IS A MUST, the amplifier's built-in fuse will only protect the power amplifier not the car's battery! Use high grade wire connectors. -
Page 5: Features And Benefits
Built-in Crossover The MDS amplifier include a built-in combination variable high and low pass crossover. The low pass filter works together with the (subsonic) high pass filter to achieve band pass filtering. This concentrates the amplifier’s output power to your subwoofer optimum frequency range . -
Page 6: Remote Turn-On
Remote Turn-on Automatically turns amplifier on when connected to the head unit's remote output. The amplifier will turn on and off with the head unit to save current consumption. This control also operates the reset circuit for the amplifier's protection. It must be connected with the head unit in order to reset protection circuits. -
Page 7: Mounting Location
OUNTING LOCATION Before you start the installation, it will be necessary to find a mounting location for the amplifier. Find a location in which the amplifier will receive adequate ventilation in order to dissipate the heat it develops during operation. Two popular mounting locations are in the trunk or under the seat. -

Page 9: Signal Connections
IGNAL CONNECTIONS Connect the RCA output of the head unit (AM/FM cassette player, CD, or DAT) to the RCA input terminals of the amplifier. To make these connections, we recommend high quality RCA cables, which are available at your local car audio retailer. Run signal wires away from electrical wires to avoid possibility of induced noise from the car's electrical system (i.e. -
Page 10: Speaker Connections
PEAKER CONNECTIONS Make the speaker connections using speaker wire that is at least 16 gauge or heavier. As with any audio component, proper phasing of the amplifier and speakers is essential for strong bass response. When connecting, make sure that positive (+) from the amplifier is connected to the positive (+) of the speaker, and the same for negative (-). - Page 11 EMOTE BASS CONTROL MODULE Before connecting the remote, it will be necessary to find a mounting location that will be easy to access for adjustment. Once you select your mounting location, you will need to run the control wire from the remote to the amplifier. To avoid possibility of induced noise from the car's electrical system (i.e.
- Page 12 DJUSTING THE X-OVER AND BASS The MDS amplifier features a built-in combination variable high and low pass crossover. The low pass filter works together with the (subsonic) high pass filter to achieve band pass filtering. This concentrates the amplifier’s output power to your woofer’s optimum frequency range for maximum performance.

Page 13: Troubleshooting The System
ROUBLE SHOOTING THE SYSTEM We have put together this trouble-shooting guide if you experience problems after installing the amplifier. Please keep in mind that the majority of problems incurred are caused by improper installation and not the equipment itself. In addition, there are many components in the system that could cause various signal problems such as inducted electrical noise and engine noise. -
