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 which 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).
Frequency Multiplication:
This feature multiplies the normal crossover frequency range by 20, thereby
allowing you to select a crossover frequency setting for the front or rear
channels, between 30Hz and 400Hz or 600Hz and 8kHz (high-pass or low-pass).
Built-in Variable Electronic
Crossover: The built-in high-pass
crossover is adjustable from 15Hz to 400Hz or 300Hz to 8kHz with a slope of
12dB/octave. The built-in low-pass crossover is adjustable from 30Hz to
400Hz or 600Hz to 8kHz with a slope of 12dB/octave. This use of separate
high-pass and low-pass frequency controls allows for bandpass operation.
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 and rear 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 15Hz/300Hz to
400Hz/8kHz
- Rear channel frequency
controls: these rotary controls
allow you to adjust the crossover frequency from 30Hz/600Hz to 400Hz/8kHz
- Front and rear high-pass
crossover switches: lets you select
high-pass or full-range operation for the speaker outputs
- Front and rear low-pass
crossover switches: lets you select
low-pass or full-range operation for the speaker outputs
- Front and rear frequency
multiplication switches: lets you
select "X1" for normal crossover frequency band (15-400Hz) or
"X20" for a crossover frequency band of 300Hz-8kHz during
high-pass operation
- Front and rear frequency
multiplication switches: lets you
select "X1" for normal crossover frequency band (30-400Hz) or
"X20" for a crossover frequency band of 600Hz-8kHz during low-pass
operation
- Input channel selector
switch: Allows you to select
between 2-channel, 4-channel, and summed input options
