Stinger Audio MT-600.4M 4-Channel Class D Marine Amplifier - 1000W RMS, 250W x 4 at 2 Ohms
The Stinger Audio MT-600.4M is a compact, water-resistant 4-channel Class D amplifier from the MT Series, made for marine and powersport audio systems. It delivers 250 watts RMS x 4 at 2 ohms, 150 watts RMS x 4 at 4 ohms, or 500 watts RMS x 2 bridged at 4 ohms (under 1% THD at 14.4V).
Inside, HEXFET power MOSFETs with low on-resistance and fast switching work with a 500V high current impulse capacitor that protects the MOSFETs from surge over-current. The power supply uses pulse width modulator ICs, and direct insert power and speaker terminals cut resistance for better power transfer.
A crossover multiplier (X1: 50 Hz - 500 Hz, X10: 500 Hz - 5 kHz) lets you run tweeters or midrange speakers without an external crossover, and bass boost covers 30-80 Hz at 0-12 dB. A remote level control and installation guide are included.
