Planet Audio MB1200.4D 4 Channel Class D Car Amplifier - 1200 High Output, Low/High Level Inputs, Full Range, Hook Up to Subwoofer for Bass

Power - 300 Max x 4 @ 2 Ohms, 150 Max x 4 @ 4 Ohms, 600 Max Bridged x 2 @ 4 Ohms ^^ Class D - Power loss is significantly reduced making the amplifier highly efficient. Excess energy is stored until its needed instead of being converted into heat. Reduction in size/weight, reduced power waste, smaller heat sink, compact circuitry ^^ Bridgeable - Dramatically increase the power output to you speakers and subwoofers by connecting two amplifier channels ^^ MOSFET Power Supply - A MOSFET is an electrical switch that allows the flow of electrical current.

It controls the output voltage & current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry ^^ Variable Bass Boost - Bass Boost allows you to adjust the low bass within the boost range to just the way you like it ^^ Variable High-Pass Crossover - Speakers reproduce sound based on high, low or mid-range frequencies. A variable high pass crossover gears specifically towards highs such as all size speakers including mid ranges and tweeters ^^ Variable Low Pass Crossover - Subwoofers reproduce sound based on a number of different low-range frequencies.

You can set exact sound specifications for the bass frequency reproduction ^^
