Above is the completed wiring for the first amp. Note the RCAs, speaker and power wires are all in place. The ground power wire(silver wire top left of picture in bolt) will be connected to the bolt holding the seat in place. We include split loom to cover the power wires and make it almost impossible to tell you have an amp under your seat(s).  This picture does now show the split loom (black wire cover).  In a later section we will cover the amp's gain, xover and db settings.  Remember to expose air vent. In this picture the vent is covered by the mat.  Also, for now ignore the sliver wires in the lower left hand corner. This is for a future project. They have not part of this installation.
