The Hertz MP 15K UNLIMITED amplifier can deliver over 15.000 W. The enormity of this project amazes both in terms of the physical "size" of the product itself and of the sheer energy it generates. The power supply stage features 8 toroidal transformers and the output stage, settable in bridged or stereo mode, features 20 -190A/360V impulsive current Mosfets: solid, robust power and thermal dissipation without compromise.

Direct Current® , the power supply connection system, transfers power between the battery and amplifier with very low contact resistance, to achieve the current transfer required for high SPL systems. The Hertz SPL Stack System® provides the ability to stack multiple MP 15K UNLIMITED amplifiers, using 6 robust iron Brackets. With the Hertz SPL Stack System® your system can deliver 15.000 W, 30.000 W, 45.000 W, or more, just stack and connect!

Features

1. In order to deliver such extraordinarily high power, the power supply stage features 8 toroidal transformers, 20 - 3300uF 105°Low ESR primary capacitors for a total of66 000uF; 32 160A TO247 Mosfets and 10 - 820uF secondary capacitors capable of 200 V. 
2. The output stage, settable in bridged or stereo mode, features 20 -190A/360V impulsive current Mosfets: robust power and thermal dissipation without compromise.
3. Direct Current®: 4 - 1/0 AWG cables (2 for the positive and 2 for the negative) terminated with ring terminals on the supply side and secured to the amplifier with 4 - 2,5 mm thick copper buss bars connected directly to the printed circuit board, providing the ability to transfer power between batte...
