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.

Overview: The MTX Thunder500.1 is a mono Class D subwoofer
amplifier. It has aluminum heatsinks to dissipate heat generated by the amplifier.
The amp produces 300 watts RMS x 1 at 4Ω and 500 watts RMS x 1 at 2Ω.
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 Thunder500.1 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 Thunder500.1'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 Thunder500.1 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 60-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 60-amps, the original should be replaced
with a 60-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
5 Year Warranty Terms: MTX products purchased on or after
January 1st, 2013 carry a 5-Year Prorated Warranty with the following terms:
- Years 1-2: Products found to be defective in materials
or workmanship during the first two years will be, at Mitek's option,
repaired or replaced by Mitek at no charge. The warranty period does not
renew, but continues on from the original date of purchase.
- Years 3-5: The purchase price of an item which becomes
defective after the first two years and prior to the end of the warranty
period will be prorated and credited toward the purchase of a new MTX
product. The amount of proration is determined by dividing the original
purchase price by the number of months in the warranty period (60), then
multiplying the result by the number of months remaining in the warranty
