Inputs and Outputs Notes
CEA 2006 Compliant: The MTX
MXA3002's power ratings are measured according to the strict standards dictated
by the Consumer Electronics Association (CEA). These standards allow you to
accurately compare the rated power output of all CEA 2006-compliant amplifiers,
even if they come from different brands. Manufacturers who adhere to the
standards can display the CEA 2006 logo on their products and packaging.
Heatsink: The amplifier's
high-mass extruded aluminum heatsink provides maximum thermal management and
Speaker-Level Input: The
amplifier comes with a speaker-level input harness, which allows you to connect
the amp to a receiver without RCA jacks. The harness wires should be spliced to
the left and right speaker wires (front or back) of the radio.
Smart-Engage: When using the
speaker-level input, the amp automatically turns on when it senses signal from
the head unit, eliminating the need for a remote turn-on connection. In many
cases, this feature will allow you to install the amplifier without removing
Bass Boost: You can select a
bass boost level between 0 dB and 18 dB to enhance the bass performance of your
sound system. The bass boost is centered at 40 Hz.
Internal Crossover: The
built-in crossover, adjustable from 40 Hz to 350 Hz, can be set for high-pass or
low-pass operation, or it may be turned off for full-range output. The crossover has a slope of 12 dB/octave.
Remote Subwoofer Level Control: The Remote Subwoofer Level Control lets you adjust the output level of
the amplifier from anywhere in the vehicle. It is only active when the internal
crossover is set to low pass operation, and will attenuate the amp or increase
its output to the level of the main gain setting. The module is attached to a
17.75' cable which plugs into the Remote Gain 3.5mm minijack on the side of the
amplifier. A bracket and mounting hardware for the Remote Subwoofer Level
Control are included with the amp.
Protection Circuits: The
MXA3002 has the following protection circuits:
- Thermal: If the amplifier
gets extremely hot, the amp will turn itself off, allow it to cool down to a
normal operating temperature.
- Over/Under Voltage: If the
battery voltage received by the amplifier is less than 11 volts or exceeds
15 volts, the amplifier will shut off. The amp's LED indicator will flash on
and off to indicate a voltage problem.
Performance Certificate: MTX
tests each amplifier, and the technician records the "actual" power output on
the Audio Performance Dyno Certificate included with each amp. The amp must meet
or exceed the rated specification in order to leave the factory.
Inputs and Outputs
Set-screw Terminals: The power
and ground set-screw terminals will accept up to 4-gauge wire. The remote
turn-on, capacitor, and speaker set-screw terminals will accept up to 8-gauge
Note: The power and
ground terminals have an attached note that reads: "You must use 4 gauge
power/ground wire!" Smaller gauge power/ground wires are not
Remote Gain: The 3.5mm minijack
allows you to connect the supplied Remote Subwoofer Level Control.
