02DESIGN
Compact ABS Housing for Discreet Installation
The unit is constructed from durable ABS plastic, finished in a solid black that resists glare and matches most interior trims. Its small footprint allows it to be mounted in tight spaces, such as behind the dashboard or within the footwell, keeping the visual clutter of cables minimal while maintaining easy reach for adjustments.
04CONTROLS
Dual Adjustment for Gain and Frequency
Users can manipulate the sound profile through two distinct methods: adjusting the gain level, which ranges from 0db to -12db, and modifying the frequency cutoff between 40Hz and 150Hz. This dual-control approach allows for granular tuning of the subwoofer’s output, enabling listeners to dial in the exact depth and punch they prefer.
CONNECTIVITY
Two-Channel Stereo Source Switching
The interface accommodates two stereo signal sources, allowing users to switch between devices like a mobile phone, tablet, or MP3 player without rewiring. Standard interface design ensures compatibility with common output devices, while the manual button provides immediate, reliable switching between connected inputs.
