Failure to do this means you re a few brews short of a 6-pack and you probablyalready acquired the nickname of Sparky or Smokey . Not cool! Do NOT hook the ground cable back up to the batteryuntil the rest of the wiring is ground wire mayneed to be upgraded, especiallyif it is smaller than thepower wire, frayed, or must beinstalled within18 of a hole in the firewall &use a rubber grommet tokeep wire from the cables under thecarpet near the side of thevehicle.

8 Be careful not todrill or screw into thewires when replacing cable tobare metal chassis/frame with nut &bolt. No screws orseat/seatbelt bolts!Run signal cables (RCA)and remote turn-on leaddown the opposite side ofthe vehicle of the powerwire to avoid radiated sharp edgesthat could chafethrough the insulation.<8>TERMINALS* Power terminal block & Speaker terminal block for / * Power terminal block & Speaker terminal block for / * Power terminal block & Speaker terminal block for * Power terminal block & Speaker terminal block for <9>* Crossovers for / * Crossovers for * Crossovers for * Crossovers for / <10>Control DefinitionsAlrighty, here comes the fun stuff.

9 We re going to break this down to it simplest form so that there is no way you can possibly do any damage in the installation process to your audio system. We re going to explain in detail how every single knob and switch work rather than turn you loose on a sophisticated amplifier and have problems. READ EVERYTHING!Trust us, it ll be worth Before you do anything, undo the ground cable from the Terminal BlockGND This is the Ground connection. Bolt the Ground cable to a bare metal part of the chassis/frame. Do NOT us self-tapping screws or seat/seatbelt bolts!

10 +12V This is the Power Connection. This cable gets connected directly to the battery. You MUST use a fuse holder or circuit breaker within 18 of the battery. All cables ran through the firewall must be protected by a rubber or plastic grommet. If you have multiple amplifiers, the main fuse or circuit breaker at the battery should be the sum of all fuses or slightly This is the remote Turn-On connection. Connect to the amplifier output or Power antenna output of the source unit. If the unit does not have a switched +12V output, you can use another switchable + Terminal BlockThis is the Speaker(s) Connection.
