Marine Grade Construction: The MBTA8250D features an 8"
waterproof poly woofer. The woofer is powered by a
built-in 160-watt (250 watts peak) digital amplifier. The patented Bass Tube enclosure design eliminates
bass standing waves for high accuracy, and superior efficiency. The enclosure is
certified salt fog and UV resistant for 5 years and the included mounting
hardware is stainless steel.
Low-pass Filter: The MBTA8250D has a low-pass filter that can be
adjusted from 60 to 250 Hz.
2nd Woofer Output: The MBTA8250D has a high-level output for
adding an optional MBT8014 (204MBT8014)
passive bass tube to double the bass. The amplifier output increases to 275
watts (peak) when the 2nd woofer is connected.
Remote Level/Crossover Control: Using the optional RBCM-250D remote control
you can control the bass output level and crossover frequency of the subwoofer from
a remote location.
Level Control: There is a rotary control on the rear-panel that
allows you to adjust the level of the subwoofer.
Crossover Control: The unit's rotary control is found on the
rear-panel and allows you to adjust the low-pass filter from 60 to 250 Hz.
Power LED: If power, ground and remote are connected properly,
the LED on back of the unit will illuminate in green.
Remote Control: Phone-type jack for use with an optional
remote control; found on rear-panel
Power Harness: Two quick-slides for use with supplied power
harness; found on rear-panel
Signal Harness: 14-pin Molex plug for use with supplied signal
Installation: Each mounting strap has an attached mounting base
that can be secured to your vehicle using the supplied self-tapping screws. Once the
mounting bases are installed, the tube is held in place by the mounting straps. For
best results, the tube should be mounted facing into a corner, and there should be
2" to 4" between the woofer and the corner into which the woofer is
