Installation Warnings and Tips:
• Disconnect the negative (–) lead from your vehicle’s
battery.
• At the installation sites, locate and make a note of all
fuel lines, hydraulic brake lines, vacuum lines and
electrical wiring. Use extreme caution when cutting
or drilling in and around these areas.
• Choose a safe mounting location away from
moisture.
• Make sure there is sufficient air circulation at the
mounting location for the amplifier to cool itself.

DBO (Dynamic Bass Optimization) Variable
Subsonic High-Pass Filter With Variable Boost (Q)
• For woofers in tuned (vented) enclosures, set the
Frequency control to a value 10Hz below the
enclosure’s resonance (tuned) frequency.
• For woofers in sealed boxes, set the control to
any value you prefer between 30Hz and 50Hz.
• Set the Boost control according to your
preference, being careful not to apply
enough boost to damage your woofer(s).
A DBO High-Pass Filter Frequency control,
variable between 10Hz and 100Hz. See above
for appropriate settings.
B DBO Boost control provides up to
12dB of boost slightly above the high-
pass filter’s frequency. See above for
appropriate settings.
