• Color – The backlit controls offer unlimited colors on the display -- from RED, GREEN, and BLUE to any color

• EFX – You can switch Prizm EFX lighting to “pulsate” with the beat of the music.

• Low Level Input – Source units with an output signal level of 100mV–10V may be used. See “Input

• High Level Inputs with Smart Engage™ – All MTX amplifi ers allow high level inputs through RCA type input

Features

• Smart-Engage™ Auto-Turn-On – An auto-turn-on circuit is included within the amplifi er. A remote turn-on

wire is not necessary when connecting the amplifi er’s high level input to a high-powered source unit (car

Note: Smart Engage™ is only active on the left input.

• GND: The ground wire from this connection must be attached to bare metal on the vehicle. The distance to

the ground should be as short as possible and no more than 18”.

• REM: To turn the amplifi er on/off, this terminal must be connected to the source unit’s “remote or electric

• +12V: The power wire from this connection must be attached to the positive side of the vehicle battery.

• CAP+: Capacitor Positive Input - The ideal connection point for the positive sides of the capacitor to increase

the amplifi er’s performance.

• CAP-: Capacitor Negative Input - The ideal connection point for the negative side of the capacitor to increase

the amplifi er’s performance.

the amp’s RCA input. This will provide signal to the amp.

• +12V: This is the main power input for the amplifi er and must be connected directly to the positive terminal

• GND: This is the ground connection for the amplifi er and must be connected directly to the metal chassis

The gauge of the power and ground wire is often an overlooked aspect of amplifi er installation. The more power

the amplifi er receives, the more power it will produce. Power cables have a natural resistance, and will lose

voltage by the time the power makes its way to the amplifi er. The larger gauge (diameter) wire will hold more

voltage over longer runs. Also, by having a larger diameter ground wire, the amplifi er can run more effi ciently.

• REM: This connection turns the amplifi er on and off and needs to be connected to a remote turn-on wire

from your source unit if you are using a low level input connection.

• CAP+: This 4 gauge terminal is internally wired in parallel with the +12V on the StreetWires Power connector.
