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.
2Ω Stable: The GTA-1000M is 2Ω stable; the lower
impedance offers higher output power:
- 600 watts x 1 @ 4 Ω
- 1000 watts x 1 @ 2 Ω
Controls and Terminals: All the controls and terminals are
conveniently mounted on one side of the amp.
Gain: Adjust the input sensitivity with this rotary control;
the range is 0.2 Volts to 5.0 Volts for line-level and 0.4 Volts to 10.0 Volts
Crossover Frequency: The low-pass crossover is always engaged,
with a crossover point continuously variable from 50 Hz to 150 Hz; the slope is 12
Subsonic Filter: The subsonic (high-pass) filter is always
on and is continuously variable from 10 Hz to 50 Hz; the slope is 12 dB/octave.
Q-Tune: Once the subsonic crossover point has been set, use
the rotary Q-Tune control to increase the bass information centered around the

065GTARSL, sold separately).
Speaker Output: One pair of set-screw terminals is provided
for connecting the subwoofer; the terminals accept up to 8-gauge wire; the set
screws are tightened/loosened with the supplied 3mm Allen wrench.
ATO Fuses: Three 35-amp ATO-type fuses are located between
the speaker and power terminals.
Power/Remote: Three set-screw terminals for connecting power,
ground, and remote wires; the power and ground terminals accept up to 4-gauge wire
(4-gauge recommended) and the remote terminal accepts up to 8-gauge wire; the set
screws are tightened/loosened with the supplied 4mm and 3mm Allen wrenches.
