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
V12 Amplifier:
This amplifier is part of Alpine's V12 series of amplifiers.
STAR Topology:
Alpine's unique STAR (Signal Transit for Accurate Response) Circuit PCB design
provides a single common ground for all amp sub-blocks, preventing ground
interference and minimizing internal noise.
Bass Engine:
Bass Engine is a set of functions that help provide you with more control over
your system in order to tailor the sound to your personal tastes.
Verification Certificate: The
amplifier comes with a certificate that informs you of the per channel RMS
output of the particular amplifier. It lists the model number, serial number,
test date, and the test conditions (voltage, impedance).
Built-in Variable Electronic
Crossover: The built-in
low-pass/high-pass crossover for the stereo channels is adjustable from 50Hz to
200Hz. The built-in low-pass crossover for the subwoofer channel is adjustable
from 30Hz to 200Hz. All crossovers have a slope of 12dB/octave.
Bass EQ:
0 to 12dB of bass boost, centered at 50Hz, may be dialed-in to produce the bass
response desired from your system.
Sub-sonic Filter:
The sub-sonic filter is used to filter out low frequencies that you cannot hear
but can "rob" power from the amplifier. The sub-sonic filter on this
amplifier affects the subwoofer channel only, and selectable between
"30Hz", "15Hz", and "OFF".
Protection
Circuitry:
The protection circuitry guards against accidents and undesired
operation. Included are Over-voltage and Thermal overload.
Controls
Top of Amplifier: The
amplifier has a metal hood that flips up to reveal the control panel. The
control panel consists of the following controls:
- Front, rear, and sub
variable gain controls: these
rotary controls allow you to match the input sensitivity of the amp to the
particular source unit you are using
- Front and rear channel
frequency controls: these rotary
controls allow you to adjust the crossover frequency from 50Hz to 200Hz
- Sub channel frequency
control: this rotary control allows
you to adjust the crossover frequency from 30Hz to 200Hz
- Crossover mode selector
switches: lets you select
high-pass, low-pass, or full-range operation for the speaker outputs of
channels 1/2 & 3/4
- Subsonic filter:
lets you select between 30Hz, 15Hz, or OFF
- Bass EQ:
this rotary control allows you to adjust the boost or cut from 0 to 12dB
- Input channel selector
switch: Allows you to select
between 4-channel, 5-channel, and summed input options
