SP 4.900 is the first Hertz amplifier featuring the renewed Hertz ADC (Advanced D-Class) output stage, reaching up to 85% efficiency and delivering an impressive power rating of 160 x 4 (4?) W RMS or 500 W x 2 (4) W RMS when bridged, with an ultra-compact size of 211.6 (8.3) x 130 (5.1) mm (in.). Being ultra-compact with an impressive power, SP 4.900 is the ideal choice for Motorcycle application and for under-seat in sport cars and behind-seat installations in trucks.

Overtakes the Usual Ultra-compact Amplifier Performances

Hertz ADC technology overtakes the usual ultra-compact amplifier performances, delivering an outstanding 105 dBA S/N Ratio and 0.02% THD specifications, and almost completely eliminating EMI and RFI noise, for peerless sound quality. This versatility is perfect to drive high power (4) front speakers with a bridged (4) subwoofer.

Fully Protected Against Overheating and DC Outputs

Fully protected against overheating and DC outputs, immediately switching in protection mode (red led on) to save your speaker system. The IP55 certified Aluminum chassis offers maximum protection against humidity and external agents and the absence of internal cooling fan prevents internal accumulation of dirt. SP 4.900 main board has conformal coating layers to prevent harm caused by internal condensation, a condition that can happen when warm, moist air meets the amp chassis of a lower temperature.

Ensures Ultra-stable Power and Ground Connection

Features a built-in sealed power cord, line inputs and speaker outputs for a bulletproof motorcycle application providing safe power delivery in even the worse weather conditions. The solid power supply harness ensures ultra-stable power and ground connection, preventing any loss of contact caused by vibration. Due to its specific design, the ultimate option for Motorcycle, Marine, and Powersports applications.
