Sennuopu HQ-3000.1D Class AB Pure Amplifier

90% of power amplifiers on the market consist of front and rear stages, where signals are processed by an op-amp before being amplified for speakers. This amplifier is pure signal amplification —no sound processing —so we recommend using a DSP or pre-processing unit (such as branded CD players or EQs) for active 3-way or 2-way setups, offering greater flexibility and lower modification costs. As a pure post-amplifier , it lacks bridging functionality , making it unsuitable for bridged subwoofer setups (e.g., 4 subs in push-pull).

Pure Amplification, DSP-Ready for Active System Customization

Unlike most power amplifiers that combine op-amp processing with power stages, the HQ-3000.1D focuses solely on amplification —bypassing sound quality alterations . For active crossovers (2-way/3-way), we recommend pairing it with a DSP or external preamp (like high-end CD/EQ units) to maximize flexibility and cost efficiency. Note: This pure post-amplifier lacks bridging , so it’s incompatible with bridged subwoofer setups (e.g., 4 subs in push-pull mode) .

Gold-Plated Terminals for Uncompromised Signal & Power Integrity

Engineered with gold-plated pure copper connections , the HQ-3000.1D guarantees high-fidelity signal transfer and stable power delivery . Its short-circuit fuse mechanism instantly activates under overload or internal failure conditions, protecting both the amplifier and your vehicle’s audio system from potential hazards.

Channel-by-Channel Control: Pure Power Amplification for Active Crossover Systems

The Sennuopu High-Power Class AB Monoblock Car Amplifier is a dedicated post-amplifier , meaning it exclusively amplifies signals without pre-amp processing or tuning functions. Each channel features independent volume control , allowing precise output power adjustment per channel. The signal input section is also channel-matched , ensuring direct compatibility with active crossover setups—ideal for enthusiasts who demand granular channel management .

Toshiba Triode Engineered: 150W/Channel @4Ω Pure Power

Featuring Toshiba’s A1943/C5200 triode pairs (Japan), the HQ-3000.1D operates in Class AB as a dedicated post-amp. Its 6 output groups provide 100W–150W per channel , with a 4Ω rated power .
