FEATURES
Your Optimus 125 × 4 High Power 4-
Channel Trunk Mount Amplifier is de-
signed to produce a total of 500 watts
to give added punch and power to your
vehicle's existing autosound system.
The amplifier produces up to 125 watts
per channel (for 4 channels) of clean,
powerful sound at all audio frequen-
cies with minimum distortion. You can
adjust the amplifier's crossover fre-
quency so you can emphasize bass
sounds without decreasing power or
other sounds. You can connect your
autosound system's low level or
speaker level outputs to the amplifier.
This amplifier's features include:
14K Gold Plated Noise-Isolated Low
Level Input Jacks
—
low level (preamplifier) signal inputs
to match your autosound system's
output for the best high-fidelity perfor-
mance.
14K Gold Plated Speaker Terminals
designed for low impedance, high
—
conductivity, and minimum corrosion,
to provide the highest signal transfer
and lowest sound distortion.
Input Level Controls
the level of the audio signals that enter
the amplifier.
Automatic Power Switching
matically turns the amplifier on or off

from each channel.
Crossover Frequency Circuit
you adjust the crossover frequency
from 45-400 Hz. This lets you set up
the amplifier so you can connect one
or two subwoofers.
Automatic Thermal Protection Sys-
tem (ATPS) automatically lowers
—
the amplifier's output power when the
amplifier's internal temperature reach-
es 202 × F (94 × C), then increases the
output power when the amplifier cools
down.
Mute Turn On Circuit
the thump you hear when you turn on
some amplifiers.
