Overview: The MTX Thunder1000.1 is a mono Class D subwoofer
amplifier. It has aluminum heatsinks to dissipate heat generated by the amplifier.
The amp produces 350 watts RMS x 1 at 4Ω, 600 watts RMS x 1 at 2Ω, and
1000 watts RMS x 1 at 1Ω.
Gain: The amp's rotary gain control is continuously variable
from 200mV to 5V to match the output of the source unit.
Protection Circuits: The Thunder1000.1 provides protection
against overheating, under voltage, and electrical short circuits.
Crossovers: The amp features a built-in low-pass crossover,
with a continuously variable cutoff frequency of 40-220Hz; the crossover cannot
be bypassed. Additionally, the amp has a subsonic filter to remove ultra-low
frequencies, thus minimizing wasted power and protecting speakers not capable of
reproducing those frequencies. It has a variable crossover frequency of 20-50Hz.
Bass Boost: The Thunder1000.1's bass boost circuit is centered
at 50 Hz. It can be set to 0dB, +6dB, or +12dB.
Electronic Bass Control (EBC): An Electronic Bass Control (EBC)
module is available directly from MTX that allows you to adjust the bass output of
the amplifier from the front of the vehicle.
Power Terminals: The Thunder1000.1 features set screw terminals
for power, ground and remote turn-on. The power and ground terminals will accommodate
up to 4 AWG wire, while the remote turn-on terminal will accept up to 10 AWG wire.
The set screws are loosened/tightened with the supplied Allen wrenches. MTX
recommends the use of 4 AWG power and ground wires.
Note: The Amplifier is not equipped with
an internal fuse. An external 100-amp fuse (not included)
must be installed on the power wire. If the system has only
this amp and a wiring kit is used that includes a fuse with
a value other than 100-amps, the original should be replaced
with a 100-amp fuse.
Speaker Connections: The amplifier is equipped with two pair
of set screw terminal speaker outputs. The outputs are internally wired in parallel,
making it easy to connect two subwoofers. Each terminal will accommodate up to 10
AWG bare wire and is loosened/tightened with the supplied Allen wrench.
EBC Port: The amp has a 3.5mm mini-jack for plugging in an
optional Electronic Bass Control (EBC) module, currently available directly from
