Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Features
Amplifier: The power output from the built-in amplifier is
300 watts RMS, 450 watts max.
Note: Neither speaker wire, RCA interconnects,
nor amplifier wiring kit (power/ground/turn-on wires) are included.
Signal Input: The amplifier will accept either a speaker
level or line level signal. The inputs are RCA jacks; if connecting a speaker
level signal, use the included bare wire to RCA adapters. The input sensitivity
range is 40mV-20V.
Crossover: The amplifier's low pass crossover point is
continuously variable from 50 to 120 Hz; the crossover slope is 12 dB/octave.
Bass Boost: The bass boost circuit provides a variable (0-12
dB) signal boost centered at 40 Hz.
Audio Sense: The signal-sensing turn-on circuit automatically
turns the MS-BassPro SQ on whenever the head unit sends an audio signal, useful in
many installations using a factory head unit that may not have a dedicated remote
turn-on wire. This feature is easily switched off for aftermarket head units that
do have a dedicated remote turn-on wire.
Slipstream: The proprietary Slipstream port's dual flares
eliminate vent noises, even at high sound pressure levels.
Wireless Bass Control: An optional MS-WBC wireless bass control (item number
109MSWBC,
sold separately) is available to remotely adjust the bass output. The MS-WBC communicates
via RF signal and requires no physical connection to the amp; it's also battery powered,
but has an optional power wire if you prefer not to replace the battery periodically.
Controls:
- Bass Boost: rotary knob; continuously
variable from 0 to +12 dB
- Crossover Frequency: rotary knob; set
the low pass crossover point; continuously variable from 50
Hz to 120 Hz
- Input Level (gain): rotary knob;
continuously variable
- Input Level Switch: three position
switch, Low, Hi, Hi2 (Hi2 is used to present a speaker
load to factory radios equipped with a circuit that turns
the radio off when an amp is connected)
- Phase: two position switch; 0° or
180°; the sub's phase can be easily inverted
- Audio Sense Switch: two position
switch; on/off; when on the amplifier will turn on
automatically when it senses an input signal
Connections:
- Power Input: screw terminals for power,
ground, and remote turn-on; each will accept spade terminals
up to 0.375" wide
- Fuse: a single 30 amp ATO style fuse
protects the amplifier
- Input: stereo female RCA jacks; used for
line level or speaker level inputs (adapter included for speaker
level inputs)
