No Amp

• 1). Disconnect the negative battery cable on your vehicle.
  
  
• 2). Find the front and rear speaker wires for your car audio system. Cut the wires from any harness that was attached to an old system. Strip the last half-inch of insulation from the wires.
  
  
• 3). Locate the wires from the DEH-P5800MP. Strip the last half-inch of insulation from the wires. Connect all of the power wires according to the manual specifications.
  
  
• 4). Slide a two-inch section of heat-shrink tubing over the speaker wire. Twist the bare metal of the wires together to make a connection. Touch the soldering iron to the metal until it's hot. Touch the solder to the metal until one drop melts off. Remove both the solder and the iron.
  
  
• 5). Slide the heat-shrink tubing over the connection, and then heat it with the gun until it shrinks around the wire.
  
  
• 6). Connect the left-front positive speaker wire to the white wire from the DEH-P5800MP. Connect the left-front negative wire on the vehicle to the white-black wire. Right-front positive goes to gray and right-front negative goes to gray-black.
  
  
• 7). Connect either the rear speakers or the sub-woofers. Remember that you will need to adjust the settings of the DEH-P5800MP to drive either the subs or the rear channels. Left-rear positive goes to green and negative goes to green-black. Right-rear positive goes to violet and negative goes to violet-black. If you're connecting the subs, the sound will be monaural, so the left-right orientation doesn't matter.
  
  

With Amp

• 1). Disconnect the negative battery cable on your vehicle. Connect all the power cables per the manufacturer's specifications.
  
  
• 2). Plug the blue-white wire into the system control terminal of the powered amplifier(s) in your vehicle.
  
  
• 3). Connect the sub-woofer amp to the far-left RCA jacks on the back of the DEH-P5800MP using RCA cables. Plug the front-speaker amp into the RCA jacks to the right of the sub-jacks.
  
  
• 4). Plug the rear-speaker amp to the 15 centimeter jack on the upper-right section of the head unit, using the adapter for that purpose to adapt it to the RCA connection.
