MHD Series 600w 4 Channel Full-Range Amplifier - MHD600/4

150 W x 4 @ 1.5-4 Ω

ULTRACOMPACT AND ULTRAPOWERFUL

Combining our Single Cycle Control™ and R.I.P.S.™ power supply technologies, MHD amplifiers deliver world-class, full-range fidelity and high-power output from an incredibly small package.

Features

  • High-fidelity Class-D design delivers superb sonics
  • Intelligently optimized for all the power - all the time
  • Full suite of studio-grade signal processing on board
  • Unique design adjusts operation to avoid thermal events
  • Exceeds international standards for salt fog and UV exposure
  • 3-Year Warranty

Single Cycle Control

Ground breaking technology applies output correction more than 400,000 times per second to deliver exceptional audio quality with reduced current draw and heat.

R.I.P.S. Technology

Regulated, Intelligent Power Supply is a tightly controlled design that maintains full power output from 1.5 to 4 ohms per channel and at any supply voltage from 11 to 14.5 volts.

Studio-Grade Signal Processing

Selectable 12 dB/octave (Butterworth) or steep 24 dB/octave (Linkwitz-Riley) filters with calibrated potentiometer to best integrate with subwoofers and component systems.

Differential-Balanced Inputs

A versatile design accepts speaker level signals without a line-output converter; it also delivers outstanding noise rejection while preventing alternator whine and other noises.

Advanced Rollback Protection

Innovative circuit design ensures that the amplifier will never shut down as a result of thermal overload and keeps the music playing, even under the most demanding conditions.

Built for the Elements

An all-aluminum, powder-coated housing with marine-grade hardware inhibits corrosion, and a watertight security cover protects all controls from the harshest of seasons.

Powerfully Neat

All MHD models share the same compact dimensions, making them far easier to place.

Realsink™ Chassis

The heat sink design requires no fans and permits stacking without losing cooling ability.

Designed To Fit

Removable power and speaker plugs aid installations in tight spaces.

Good value for a $55 boot.
Size: 12, Color: Army Green
I like these boots because I have a wide foot and even though I bought the 12 and NOT the 12W there is plenty of width. Very comfortable boot. I have put this pair through about 1000 miles mostly on asphalt, ice and snow. Very little actual dirt/ rocky trails. I bought them for the waterproofness and ankle support. Now the soles are getting thin and I can feel small rocks through the soles. Plus the soles are beginning to separate from the uppers and they are no longer waterproof. Not bad for 1000 miles. Still, I feel For a $55 boot they are a good value. I am 6ft and weigh 250.

Worth Every Penny!
Size: 9, Color: Coyote
I absolutely love these boots! They are super light, comfortable and definitely waterproof. I took them on a camping trip for the weekend and I walked through creeks and puddles with no issues at all. No water got inside and they were comfortable all weekend. The only thing was the tongue did start to bother me a bit after the 3rd day. I have some pretty boney shins but a small cloth between my shins and the tongue helped a lot.

Excellent boot for the price! Very solid. Cushy insoles very comfortable. Wide width plenty wide. Recommend getting half to full size smaller than your usual.
