Hertz SPL Show HP 802

Hertz SPL Show HP 802 - 2-Channel Class AB Amplifier, 1-Ohm Stable

The Hertz SPL Show HP 802 is a 2-channel Class AB amplifier that reliably delivers power in demanding SPL and everyday systems. An oversized power supply with four toroidal transformers ensures stable reserves – even at 1-Ohm loads. With separate high and low-pass filters and parametric EQ, you can precisely adjust the sound to your setup. Available at Carhifi.shop.

Practical Use

Whether for a front system plus subwoofer or bridged in mono mode: the HP 802 remains controlled and delivers clean dynamics. The high damping factor supports precise bass, and the wide bandwidth keeps the signal transparent. With the full-range pre-out, you can easily connect additional amplifiers if needed.

Installation & Compatibility

The amplifier is designed for 12V vehicle electrical systems and operates stably down to 1 Ω in stereo mode or 2 Ω bridged. Plan the power supply to match the possible current draw of up to 100 A. The adjustable filters make it flexible for use in active setups – from band-pass for mid-range speakers to low-pass for subwoofers.
