Wiring the Amp
On the Amp, you will see a number of connections.
Your thick Red lead, the Live Lead, will go on the connection that says +12v.
Your thin Blue lead, the remote live, goes on the connection that says REM, or REMOTE.
Your Black lead, the earth lead, will go on the connection that says GND, or EARTH.
Next to these connections are another set of connections, for you Sub.
Depending on what channel amp you have will determine how many connections you have. If you are just running a single sub off your amp, then you need to "Bridge" the connections.
Basically that means take the negative connection on the far left hand side and put your negative speaker wire in there, and take the positive connection on the far right hand side and put your positive speaker wire there.
