Reliable loudness and bass impact - with 900 Watt 2-channel output

A two-channel topology supplies separate channels for left and right speakers while allowing a single-channel use for a sub, rated at 900 Watt total. Power delivery gives headroom for louder playback without immediate clipping when properly matched to speakers.

Greater volume and firmer bass response during drives, especially when replacing a weak factory amplifier. Keeps dynamics intact at higher listening levels for clearer, more enjoyable tracks.

Straightforward instalment with factory systems - with high-level input

High-level input accepts speaker-level signals from OEM or aftermarket head units, so a line-level converter is not required. Wiring adapts to common factory outputs, simplifying integration with existing vehicle electrics.

Upgrade without changing the original stereo in many cars, reducing installation time and complication. Ideal for owners who want more power without a full head unit swap.

Cleaner speaker response - with variable high-pass filter

Variable high-pass filter (HPF) lets the installer set a cutoff frequency to block unwanted low frequencies from reaching smaller speakers. Adjustable crossover control helps protect speakers and shapes tonal balance.

Removes excessive bass from door speakers for clearer mids and vocals, making system tuning faster and more effective. Particularly useful when pairing separate subwoofers with smaller satellite speakers.
