Read This First
Installing a car audio system is a serious project. If you have any doubts about your ability to
execute any of the installation steps found in this manual, save yourself a lot of grief and contact
a professional installer. Your Polk Audio dealer is a good place to find one. If you intend to do the
installation yourself we assume you possess some skill in the proper use of hand and power tools.
No matter how much installation experience you have, we recommend that you…
• Read this manual thoroughly before you begin
• Plan your installation carefully
• Allow enough time to complete the installation without rushing
• Take steps to protect your car and upholstery from unwanted scratches and punctures.
• Wear proper protective safety gear.
Tools you May Need
• Phillips head screwdriver
• Panel pry tool
• Electric drill and 3/16" and 1/8" drill bits
• Permanent ink marker or pencil
• Solderless, crimp-on connectors and a crimping tool
• Safety glasses
• Wire strippers and cutters
• Electrical tape
• Grommets for passing wires through metal car walls
• Amplifier Power Wire Kit (available at your authorized Polk Audio Dealer)
Safe Limits of Operation
Your Polk Audio AutoSound equipment is constructed of the highest quality materials for years of
trouble-free performance. You should be aware that damage to loudspeakers can occur when an
amplifier, regardless of its wattage, is made to play at higher listening levels than its power can
clearly produce. Operation at this level can result in very high levels of audible distortion originat-
ing in the amplifier, which can add a harsh, gritty sound to your listening material. If you hear
distortion—turn it down or risk damaging your speakers. You can damage any speaker, regardless
of power rating, if you push any amplifier, regardless of power rating, to the point of distortion.
All Carbon Series Amplifier Models Feature:
• Polk’s Maximum Dynamic Headroom (MDH) Power Supply allows Polk/MOMO Amplifiers to
deliver more instantaneous power peaks, easily driving your speakers during musical peaks. Get
“max headroom” (!) and more power for low impedance loads.
• Each model features fully adjustable electronic crossovers to power any install using any speakers
on the market.
• Each model also features the exclusive Polk/MOMO Pre-EQ Switch, which optimizes the
crossovers for use with Polk/MOMO Ultra High Performance Speakers and Subwoofers so you can
take high performance to whole new level.
• 5-Way Smart System Protection (SSP) circuits: Power and Ground-Reversal Protection, Thermal
and Short Protection, Current Overdraw and Low Impedance Protection circuits with auto-
Standby Mode ensure safety, reliability and durability.
• Hideaway Cover Plate conceals the wiring and the “Set It Once” user-adjustable controls for
clean-looking, fiddle-free installs.
• Polk Performance Certificate attests to each individual amp’s Power Rating, and serial number.
• High-density split-dome convection heat sinks with more surface area than standard fins for
extreme heat dissipation and a long, reliable life of high amplification. No need for noisy fans.
• High damping factor improves driver control for tighter, punchier bass.
• Subsonic Filter (15Hz@24dB/octave) for an extra level of speaker protection.
• Remote Subwoofer Level Control available on all models (a stock feature on the mono sub amp).
• Power, Thermal and Short Protection LEDs easily visible on top plate.
