- POLK AUDIO Owner's Manual CAR SPEAKER EX3

98
AMPLIFIER POWER REQUIREMENTS
Your new EX3 Loudspeaker will work well with a variety of electronic components. As little as 10 watts
per channel will deliver adequate listening levels in most cars. If you have a noisy car or intend to play
your system at loud listening levels, more power will be necessary to achieve the best performance.
Consult your Polk Audio dealer for specific amplifier recommendations.
SAFE LIMITS OF OPERATION
Your new EX3 Loudspeakers are made with the highest quality materials for years of durable, trouble-
free performance. However, damage can occur to loudspeakers when an amplifier, regardless of its
wattage, is made to play at higher listening levels than its power can clearly produce. This is usually
beyond the “1 to 2 o’clock” position on the volume control. This results in very high levels of audible
distortion, originating in the amplifier, which add a harsh, gritty sound to your music. Contrary to
popular belief, a speaker is more likely to be damaged by trying to get too much volume from a low-
powered amp than from a high-powered one.
TECHNICAL ASSISTANCE OR SERVICE
If, after following these hookup and installation directions, you experience difficulty, please double-
check all wire connections.
Make certain your electronic equipment is operating correctly by hooking up another speaker to the
speaker output. For example, if you are not getting sound from the left channel speaker, connect the
right channel speaker to the left output. If you still get no sound from that side, the problem is in your
amp or source electronics. Should you isolate the problem to the speaker, contact the authorized Polk
Audio dealer where you bought your speakers. Authorized Polk Audio dealers are the best source for
advice and assistance.
