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-2002GTR 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
Protector LED: The amplifier
has an LED on the top panel that glows red when the protection circuit is
Low-pass Filter: This amp is
equipped with a low-pass filter, continuously variable from 50-300Hz, with a
slope of 12dB/octave. You can turn off the filter for full-range operation.
Inputs and Outputs Notes
The power and ground screw terminals are 0.54" wide to easily accommodate
Preamp Output: This amplifier
includes a stereo preamp output, which allows you to send an unfiltered signal
to another amplifier. You must be using the line level input, not the
speaker-level input, in order to use the preamp output jacks.
Speaker-level Input Harness:
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.
Bridging the Amplifier: When
bridging the amplifier, the line input jack and speaker output terminals labeled
"BTL" are used. The input signal is plugged into the left channel input and the
output signal comes from the left positive and right negative speaker terminals.
RMS Power Output (supply voltage at
- 200 watts x 2 into 4 ohms (20Hz
to 20kHz, 0.1% THD)
- 250 watts x 2 into 2 ohms (20Hz
to 20kHz, 0.15% THD)
- 500 watts bridged into 4 ohms (20
Hz to 20kHz, 0.15% THD)
Maximum Power Output:
- 400 watts x 2 into 4 ohms
- 600 watts x 2 into 2 ohms
- 1200 watts bridged into 4 ohms
Current Drain: at rated output:
48A (at 4 ohms)
Amplifier Wiring: This
amplifier uses two 40-amp fuses, so its total fuse rating is 80 amps. The
Streetwires 4-gauge amp wiring kits (item #s 211PS4B, 211PS4R, 211PS4BI,
211PS4RI) include an 80-amp fuse, and will accommodate the amp's fuse rating.
Other 4-gauge amp wiring kits carried by Crutchfield include a 60-amp fuse. If
you are using a 4-gauge amp wiring kit with a fuse rated less than 80 amps, the
fuse should be replaced with an 80-amp AGU fuse (item # 211AGU80).
