The MA Audio HK-802SX  4,400 watt RMS 2 channel car amplifier with a powerful built in cooling fan is built to be rugged and tough, and is more efficient and powerful than any amp in this price range.  With 4,400 watts of real RMS output power, this is one of the most powerful amps on the market.  The hot new look of this amp is incredible, and will make the finish your install look more attractive, not too mention this amp has a top mounted digital display, un-like no other amp we have ever seen!  As you can notice in the first picture, this amp has a digital display located on the top of the amp which displays the Voltage, Temperature & Output Level.

This is a high end amp with 4,400 watts of real efficient pure power.  This amp has built in advanced low pass and high pass crossovers, and is designed to give you the best sound quality.  This amp is more efficient and powerful than other amps because this is part of the high current series.  High Current means that each watt is more efficient, because at higher voltages, each watt is twice as effective.  The formula for measuring real sound power, includes the voltage, and the higher the voltage, the louder the total sound output. 

MA Audio is one of the best car audio brands around today.  They make it affordable to get the best built and best sounding amps, with real specs that don't lie.

Please note in order to get the full power out of this amp, we reccomend getting the proper power supply, such as a Kinetik battery and /or a high powered capacitor.  This amp can only perform at full capacity if you re-inforce it with the proper power supply.  It pushes serious power, so the proper power supply is necessary to get all the juice out of the amp.  This amp with the right power supply will give you competition winning amounts of bass.  This is one of the most powerful amps we ever carried.
