Designed to Deliver High-quality Sound

ntroducing the Hertz SP Compact Amplifiers: a lineup of high-performance models including the flagship SP4.900 delivering 160 x 4 W RMS at 4, the SP4.500 with 90 x 4 W RMS at 4 in a four-channel configuration, and the mono model SP1.900 boasting 1000 W RMS at 1. These amplifiers feature Hertz’s innovative ADC (Advanced D-Class) output stage, achieving up to 87% efficiency and combining impressive power with a remarkably compact design ideal for motorcycle, sports car under-seat, and truck behind-seat installations.

Built-in Crossover

Powered by advanced ADC technology, these amplifiers excel with exceptional sound quality, boasting high signal-to-noise ratios and low total harmonic distortion while effectively eliminating EMI and RFI noise. Engineered with an IP55 certified aluminum chassis, they offer maximum protection against humidity and external elements, complemented by a conformal coating on the main board to prevent damage from internal condensation, ensuring durable performance. Ideal for driving high-power front speakers and bridged subwoofers, SP amplifiers feature comprehensive protection mechanisms against overheating and DC outputs, swiftly activating protection mode when necessary to safeguard your speaker system.

Built With High-quality Materials

The versatile crossover filters and control knob are all located on a single side, to allow an easy calibration when the product is installed. The filters section includes extremely flexible high-pass and low-pass crossovers, adjustable from 50 Hz to 5 kHz with 12 dB/Oct slope. Together with a bass-boost control (45 Hz, 08 dB), they allow both front channels to be configured for full-range operation, or for use with a subwoofer and related speakers. The high-pass crossover can also be used to optimize the performance of SPL Show NEO high-efficiency coaxial speakers, the perfect partners for SP amplifiers.
