⚡ At a Glance
- • Sound Signature: Tight, controlled bass, clear mids and crisp highs
- • Best for: Drivers upgrading a stock system who want dependable power and clarity
- • Not ideal for: Users needing built-in hands-free, DSP or advanced tuning controls
Class AB two-channel amplifier built for compact car installations. Robust components and conservative design focus on reliable, clear performance.
Powerful, consistent output - with Class AB amplifier and power MOSFETs
Class AB topology blends linear amplification with efficient switching, while power MOSFETs and audio-grade capacitors manage current delivery and reduce distortion. The design preserves headroom for dynamic musical peaks.
Sustained channel power produces clear, low-distortion sound for everyday listening and dynamic passages without audible strain.
Tailored bass and speaker protection - with adjustable high/low pass crossover (40 to 400 Hz)
Onboard crossovers let installers choose high-pass or low-pass filtering across a 40 to 400 Hz range, directing appropriate frequencies to speakers or a subwoofer. Settings can be matched to speaker size and enclosure type.
Precise crossover control tightens bass and prevents low-frequency overload on smaller speakers, improving overall system balance.
Cleaner installs and automatic switching - with high/line-level Auto Power On sensing
High-level input will trigger power when a DC voltage greater than 2.5V is present, while line-level input responds to a +12V signal. Remote turn-on wiring is optional when head unit signals are present.
Simplifies integration with factory systems and reduces wiring complexity, so amplifiers power on automatically with the source unit.

❓ Frequently Asked Questions
Q: How much continuous power does the amplifier deliver?
A: It delivers 2 x 65W RMS (130W total) across two channels, with up to 500W peak headroom. A bridged mono option is specified for a single subwoofer at 170W RMS.
Q: Can the amplifier be tuned for speakers or a subwoofer?
A: Yes, adjustable high-pass and low-pass crossovers allow selection between 40 Hz and 400 Hz to match speakers or a subwoofer.
Q: Will the amplifier turn on with a factory head unit without a remote wire?
A: Yes, high-level input will auto power on when DC voltage exceeds 2.5V, and line-level input will turn on with a +12V trigger, reducing the need for a separate remote turn-on wire.
