Protect Your Hearing!
Now that you’ve got Polk Audio equipment in your car you’re a valued member of the Polk Audio
family. We want you, and your hearing, to be around for a long, long time. We urge you to practice
restraint in the operation of this product so as not to damage your hearing (and that of other
people in your car, or in your neighborhood). Studies have shown that continuous exposure to
high sound pressure levels can lead to permanent irreparable hearing loss. And then you’d be
no good to us. This and all other high-power amplifiers are capable of easily producing sound
pressure levels that can be dangerous.
Please use common sense in the operation of this product. Limit your exposure to continuous high
volume levels, and consider operating your audio system while driving in a manner that still
allows you to hear necessary outside noises like sirens and horns.
Technical Assistance or Service
If, after following the hookup directions, you experience difficulty, please double-check all wire
connections. Should you isolate the problem to the amplifier, contact the authorized Polk Audio
dealer where you made your purchase, or contact Polk Audio Customer Service 800-377-7655
(M-F, 9-6 EST, US only) or via email [email protected]. Outside the US, call 410-358-3600.
More detailed information—including audio how-to articles, FAQs, and online manuals—is
available on our award-winning website www.polkaudio.com.
There are no user serviceable parts or fuses inside the amplifier. The unique nature of the circuitry
in the Polk Audio Carbon Series Amplifiers requires specially trained service personnel. Do not
attempt to service this amplifier yourself or through unauthorized repair facilities. This will not
only void the warranty, but may result in the creation of more problems within your amplifier.
