SPEAKER WIRING AND CONFIGURATIONS
Speaker Load
Keep in mind your PowerBass Autosound Class D amp is a high power amplifier and not a high current
amplifier.
In other words it requires a minimum impedance of 1 ohm.
If you are unsure of calculating
impedance loads please consult your Authorized PowerBass Autosound Dealer before damaging your amplifier.
Too low of an impedance could send your amplifier into protection mode and/or damage the amplifier.
NOTE:
Know your impedance load before connecting speakers.
Subwoofer Wiring
Choose the correct speaker wire for your application. We recommend a minimum of 16 gauge wire. Route
these using the same precautions as you did when you ran the power cable. Terminate these wires at the
speaker end using insulated speaker terminals (not supplied) or by soldering the connection to the speaker. Be
certain to maintain correct polarity throughout the system. Make sure the speaker connections are positive-to-
positive and negative-to-negative. Most speaker wire has some indicator (color code, ribbing, or printing) on
one of the two wires to help you distinguish the positive (+) and negative (-) leads.
At the amplifier end, insert the stripped (bare) speaker wires into the properly marked terminals. Use an Allen
wrench to loosen the speaker terminals on the amplifier. Make certain that no bare wire ends touch each other.
Such contact could result in an electrical short and cause the amplifier to turn off (short circuit protection) or
malfunction.
NOTE:
It is highly recommended that a hand driver and NOT a power drill is used to
tighten the set screws on the terminal blocks. This will prevent stripping or other possible
damage to the amplifier.
