Maximum pumping power at Hertz DP 4.300?

The DP 4.300 Amplifier from Hertz has a pumping power of up to 840 W RMS at 14.4 VDC, with an accepted THD of 10%. This power is distributed across various channel configurations. With four channels at 4 Ohms, you get 75 watts per channel, and at two Ohms, 105 watts per channel. The 3-channel configuration at 4 or 2 Ohms allows for an additional 210 W on one channel. For 2 channels at 4 Ohms, 210 W is available for each. These high-performance parameters contribute to enhancing the overall audio experience.

What distinguishes the Hertz DP 4.300 at minimal load?

For the DP 4.300, specified minimum load impedances are crucial for safety and sound optimization. The Amplifier supports operation at 2 Ohms when using four channels, while the three-channel load condition is at 2 Ohms + 2 Ohms + 4 Ohms. When using only two channels, the minimum load is 4 Ohms. These flexible options ensure that you can use the Amplifier in various speaker configurations to consistently achieve high performance with minimal distortion and maximize the operational safety of the Amplifier.

How do I start the installation of the DP 4.300 in the car?

Installing the Hertz DP 4.300 requires precise steps, starting with placing the Amplifier in a well-ventilated area of the vehicle, as optimal cooling is essential. Pay attention to the dimensions to accurately assess the space requirements in the interior. The power supply connection should be between 6.5 to 16.5 VDC, with proper fusing at 20 A. The symmetrical input wiring should be done on the preamplifier or speaker input side. Adjustments to high/low pass Crossovers and sensitivity should be made to optimize performance and compatibility with the vehicle's speakers.

Versterker was goed verpakt, En heb dit beest heeft zo veel power!

Versterker was goed verpakt, En heb dit beest gelijk getest op volume en klinkt geweldig op mijn subwoofers, Het geluid vervormd niet zelfs op vol volume klinken de bas tonen zuiver, Ben vooral blij dat ik deze versterker gekocht heb. Ik geniet van elke seconde in mijn auto,Ik kon het merk niet van de versterker [gs-audio] maar het is top merk en het is met de hand gemaakt en komt uit Italy is echt goed gemaakt alleen mijn auto heeft het zwaar te verduren alles beweegt, Dus top aankoop gedaan.
