Congratulations on your purchase of a MDS state-of-the-art power amplifier. Your selection of a MDS product indicates a true appreciation of fine musical reproduction. Whether adding to an existing system or including your MDS amplifier in a new system, you are certain to notice immediate performance benefits.
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.
Built-in Crossover The MDS amplifiers include a built-in variable high and low pass crossovers. The low pass crossover features a variable frequency selection (50Hz ~ 250Hz)and the high pass crossover is fixed @ 80Hz.
Power Fusing This protects the amplifier against short circuits and excessive current. 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.
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.
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.
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 (-).

PEAKER CONNECTIONS (BRIDGED) The MDS amplifiers are capable of being bridged in a mono configuration. This feature allows you the flexibility of using the amplifier to drive a ** subwoofer or a center channel. In this configuration the amplifier sums the right and left channel to deliver one channel (mono) output.

4 Ohm connections. If you wish to use multiple speakers to achieve a lower impedance and higher power, it is strongly recommended that you seek professional advice from your MDS retailer before attempting to make these connections.

DJUSTING THE X-OVER AND BASS (Please note: If you intend to use the amplifier in the Tri-mode configuration, it is necessary to set the crossover control to the “FLAT” setting in order to receive full range output) The amplifiers are equipped with a built-in variable crossover network allowing you to select the crossover type (i.e.
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.
