Proper system planning is the best way to
maximize your amplifier performance. By
planning your installation carefully you can
avoid situations where the performance of the
reliability of your system is compromised. Your
authorized dealer has been trained to
maximize your system's sonic potential. Your
dealer is a valuable resource in helping you
with your system design and installation.
Speaker requirements
Each channel of your amplifier can easily drive
4Ω speaker loads when used in the stereo
mode. When a channel-pair is bridged, the
recommended minimum load impedance is 3Ω
for subwoofer use, and 4Ω for full range
operation. Although operation with lower
impedances is not likely to cause immediate
damage to the internal circuitry, the unit will
most likely overheat, causing the thermal
protection circuitry to shut down the amplifier.
When the chassis cools down, normal
operation will resume. Continuing to operate
the amplifier under these conditions is not
recommended and will reduce its life
expectancy.
Most speakers designed for car audio
operation are 4Ω impedance. Connecting two
such speakers in parallel will result in a 2Ω
impedance load as seen by the amplifier.
Some subwoofer models feature a dual 4Ω
voice coil design. Connecting these voice coils
in parallel will result in a 2Ω nominal
impedance, which is not recommended for use
with bridged channels of your amplifier.
