3.3 Wiring layout

+12V, GND, REM connection chart  

 We recommend using 12 AWG speaker cables to obtain increased performance.

Run 12 AWG speaker cables from your speakers to the amplifier’s mounting location
Keep the speaker cables seperate from the power cables and and the amplifier’s input cables. 
Use grommets where the cables have to penetrate the vehichle’s chassis. 
Connect the speaker wires according to the terminals on each speaker.
Strip  3/8" of  insulation  of the  end  of  each  cable  and  twist  the  cables  strands together tightly.
Make sure there are no stray strands that might touch other cables or terminals and cause a short circuit.
Crimp spade plugs over the cable ends or tin the ends with solder to provide a solid terminal. 
Connect the cable ends to the amplifer as shown in the speaker wiring diagram.
