    Output connections are not common chassis ground. Please follow the hookup instructions in this owner’s manual. Any questions should be directed to your local Zapco dealer or call us at 209-577-4268.
  • Page 5: Wire Size

    Wire Size Most people understand the importance of a clean signal source for good sound reproduction. But, what about your 12 volt power source? It’s often surprising how many people (even professional car sound people) will obsess about signal wire but routinely provide the amp only a fraction of the current it needs to do its job.
  • Page 6: Installation Guidelines

    Installation Guidelines Mounting your i-Force Amplifier is easy. Keep in mind the following guidelines: • The amplifier may be mounted in any direction, on wood, metal or carpet. • The metal case of the amplifier may be grounded or left isolated. •...

  • Page 9: I-Force Inputs

    i-FORCE Inputs To provide maximum versatility, i-Force amplifiers provide both RCA and SymbiLink™ inputs. They also provide Balanced High Level inputs that can hook directly to your speaker outputs of your factory system. Below are the wire codes for the Balanced High Level input plugs. Warning: The black reference ground wire must be hooked up to the head unit’s chassis ground or performance will be seriously degraded! Mono and 2 Channel Input Plug...
  • Page 10: Bass Boost Control

    Bass Boost Control To provide more of the control you want with your system, we have developed a unique wired remote gain control for i-FORCE amplifiers. The i-Force remote is included with every i-Force amplifier and is activated whenever the crossover is switched to low pass mode. The upper limit of volume, for the remote, is controlled by the gain control on the amp itself.

    Speaker Wiring To properly connect your system, it is critical that you understand the load your speakers will put on the amplifier. To this end you should know how your hookup affects the load. You can hook multiple speakers to a single output in three ways. The first is a Series Circuit.
