Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Inputs and Outputs Notes
The Sony XM-D9001GTR amplifier has 3-way protection circuitry, which protects
the amplifier in the following cases:
- Thermal: shuts off the amp
when the operating temperature is too high
- Short circuit: shuts off
the amp when the speaker outputs are short-circuited
- DC Offset: shuts off the
amp when the speaker wires or ground lead is not securely connected,
generating direct current
Filter: The internal low-pass filter can be adjusted from 50 to 300 Hz. The
slope of the filter can be set to 12 dB or 24 dB per octave.
Bass Boost: For added low
frequency performance, this amplifier has a 0 to +10 dB variable bass boost
centered at 40 Hz.
Filter: The subsonic filter allows the amplifier to block ultra-low
frequencies that your subs can't reproduce, improving the efficiency of your
speaker system. The filter can be set to 6 Hz or 70 Hz. The slope of the filter
can be set to 12 dB or 24 dB per octave.
Preamp Outputs: The
preamp output jacks provide a convenient source for daisy-chaining an additional
amplifier without running an extra set of RCA cables from the front of the
vehicle to the amplifier location. These outputs provide a full-range signal.
Inputs and Outputs Notes
Power Connections: The power
and ground connections are 0.547" wide screw terminals that will accommodate up
to 4-gauge wire. The remote turn-on terminal is 0.349" wide and will accept up
to 8-gauge wire. A Phillips-head (not supplied) is required to tighten/loosen
Speaker Connections: The
speaker terminals are also 0.349" wide and will accommodate up to 8-gauge wire.
A Phillips-head (not supplied) is required to tighten/loosen the terminals.
High Level Input: The amp comes
with a 2-channel speaker-level input harness with a 4-pin Molex plug on one end.
This allows you to more easily connect this amplifier to a factory deck or a
receiver without preamp outputs.
Amplifier Wiring: This
amplifier uses three 30-amp fuses, so its total fuse rating is 90 amps. Since
pre-packaged 4-gauge amplifier wiring kits normally have 60-amp or 80-amp fuses,
you will need to replace the fuse and fuse holder in the kit with a 100-amp ANL fuse (item # 211FANL100) and ANL fuse holder (item # 211FHXL4).
