Upgrade your power for better sound

You'll get some serious MTX bass mojo when you put the THUNDER1000.1D mono amp in your car. This compact amp will drive your subwoofer setup with up to 1,000 watts RMS. Hook this amp up to a nice set of subs, and you'll hear sounds you've never heard before, even in your favorite songs.


MTX knows that your system changes over time, and this amp will adapt to almost any subwoofer situation. It'll send 350 watts to a single 4-ohm sub now, but it's capable of delivering up to an awesome 1,000 watts to a 1-ohm load, so you don't have to buy a new amp to handle a multiple sub setup later on. It's amazing to think that so much power comes from an amp that'll almost fit on a piece of computer paper. This little bruiser will truly fit in places where amps don't usually go.

Advanced tone control

You can adjust the low-pass filter and subsonic filter to get the best possible sound from your sub and enclosure. In the unlikely event you want to bump up the bass a little, you also have access to a selectable bass boost.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

This Amp Really kicks Ass I am powering 2 12' 2ohms 'MTX Road Thunder Ported & the Gain level is not even @ 25% and my 2003 Honda Odyssey wants to fall apart "CLEAN CHEST POUNDING BASS"......NOTE: WHEN SETTING THIS Amp you must set the Voltage to work properly with your speakers great value for the $$$

Crutchfield Customer Review (What's this?)

The look the feel and the power Is just amazing for the small physical size of this very powerful amp!!

Pros: great price!! small in size with huge output, stays cool under heavy use operating at 1 ohm. 5 year warranty!!! Sound is definately a much more higher quality bass and no clipping at its output level unlike my old amp that in order to get loud it had to clip a little.

Cons: no on board fuses luckily i had an extra 100A fuse and fuse holder.

Crutchfield Customer Review (What's this?)

After receiving this amp I at first thought, where's the rest of it!? I installed it hoping for the best but expecting the worst. After literally smoking my old subs the first 5 minutes in. I replaced them with a fresh pair of Alpine SWS-12D4's stepped down to 1-ohm mono in an off the shelf ported box. I was thoroughly impressed. This thing is a killer! Don't use under-rated subs unless you feel like replacing them...frequently. I just wish had came withe remote bass control witch is an optional add-on.

Pros: Small foot print Massive power output Open lug terminals vs spade terminal w/screws Great Value Remote Bass Control Option

Cons: No inboard fuse, must add extra in-line Remote bass control is extra purchase

Product Research



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 MTX.


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 period.
