Improper wiring connections could cause damage to your vehicle's electrical system
and/or the 3558 amplifier. Carefully follow the wiring instructions in this manual.
Attaching the battery lead to the positive (+) terminal of the battery should be the last
connection after all other connections are made.
Due to the high power output of the 3558, it is important that all connections are clean
and well secured, or damage could result.
Be sure that the 3558 is mounted in a way that will allow for free air circulation and
heat dissipation.
When changing fuses, be sure to replace the old fuse with one of the same
amperage. Use of improper fuses can lead to serious damage to components.
The 3558 amplifier consumes a battery current of 5A under no signal condition
because of a Class A type amplification circuit used. So we recommend you do not
use the amplifier under the engine off condition. If used the battery will be wasted
rapidly. ,
