    What?
    Got these 2 amps on ebay for $110 shipped & in mint condition. Remember, these old MTX amps are way underrated in the power department.

    • 18dB/octave, continuously variable crossover with reverse outputs. For example, when you have the crossover set to low-pass, you have a high-pass output. This makes it much easier to connect multi-amplifer systems.
    • Symmetrical power-supply distributes the heat evenly across the amplifier. This makes it more reliable (meaning, it plays louder).
    • External Bass Control (EBC) port lets you adjust the bass from your seat with the optional EBC unit.
    • Individual Gain Controls to center up the soundstage.
    • Giant MOSFETS (we're not exaggerating - they're huge). A larger MOSFET means power supply stability, and a more reliable product.
    • 8 Volt RMS Input - This large signal capability allows for better integration with high voltage output source units, increased dynamic range, and better Signal-to-Noise ratio in the audio system.
    • Continuously Adjustable Thunder EQ bass boost, centered at 40Hz. To severely boost the low-end, and the attention you get from other drivers and innocent bystanders.
    • Unique Split Shield bottom plate design, reduces electromagnetic interference, to improve signal-to-noise ratio and reduce distortion. This design is so hot, we patented it so others can't leech off our genius. (Patent # 5,521,792)
    • ISO-FEET TM nylon mounting feet, eliminate the possibility of chassis-to-chassis ground noise. Leeches beware, this one's patented too. (Patent # 5,521,792).
    RMS Power measured at 12.5 Volts DC:
    75 Watts x 2 into a 4 Ohm load with less than 0.05% THD+N
    150 Watts x 2 into a 2 Ohm load with less than 0.1% THD+N
    300 Watts bridged into a 4 Ohm load with less than 0.1% THD+N

    Dynamic Power (IHF-202 Std) measured at 14.4 Volts DC
    120 Watts x 2 into a 4 Ohm load
    212 Watts x 2 into a 2 Ohm load
    425 Watts bridged into a 4 Ohm load

    Signal to Noise Ratio:
    > or = 110dB A-Weighted

    Damping Factor:
    >200
    Frequency Response:
    20Hz-20kHz±0.25dB

    Thunder EQ:
    Variable Bass Boost (0-18dB) centered at 40Hz

    Crossover:
    Variable 50Hz to 200Hz, 18dB/Octave, High Pass or Low Pass Configurable

    Dimensions:
    9" x 9" x 2" (22.9cm x 22.8cm x 5cm)
    10-1/4" x 9" x 2" (26cm x 22.8cm x 5cm) Including IsoFeet([SIZE=-2]TM
    )

    or not explode after any hope of a return is possible
