Newbie Review by Sean Newbie Product Reviewer:
The MTX Thunder 311D Car Audio Amplifier features:155 watts x 1 at 4 ohms, 310 watts x 1 at 2 ohms, requires 8-gauge power and ground leads wiring and hardware not included with amplifier, Adaptive Class D Technology, 85 Hz low-pass crossover, 18 dB/octave, preamp outputs, PWM MOSFET switching power supply,gain control, selectable Thunder EQ bass boost (0/6/12 dB at 40 Hz), speaker-level inputs with SmartEngage (turns on the amp when it detects signal from the receiver, eliminating the need for a turn-on lead), 8-1/16"W x 2-1/4"H x 9-13/16"D, and comes with a 1-year warranty. “ It delivers a relatively clean (not the cleanest I've heard, but far from the worst) high-powered sound for a price that would be hard to beat”.
