Why Choose This Product?
The APHT-1000.4D-H2 offers multiple power configurations in one full-range amplifier. Its stated stereo and bridged ratings make it possible to plan around different supported channel and load arrangements.
The fixed 90Hz high-pass and low-pass filters provide defined crossover points, while the bass boost control offers adjustment from 0–12dB. The wired remote adds convenient subwoofer level control without needing to reach the amplifier.
Installation & Compatibility Notes
Check your speakers’ impedance and intended wiring configuration against the amplifier’s listed stereo and bridged ratings before installation. Confirm that the mounting space accommodates its 8.3" × 7.9" × 2.4" dimensions.
Use the stated 14.4V conditions when comparing the continuous power ratings. Plan the installation around the system’s electrical requirements and the amplifier’s connection and mounting needs.
Frequently Asked Questions
