Also, such an installation more easily supports a standard 2 speaker woofer box that may already be constructed. Since two woofers can play 6 decibels louder than one at a given power (due to acoustical laws of “mutual-coupling”), the resulting sound pressure level is substantial. This is probably the most common use for a conventional two channel amplifier there is.

This line should NOT be run to the fuse panel of the vehicle but directly to the battery. DO NOT run to the alternator either. There MUST be a fuse installed at the battery with adequate amperage as shown in the chart above. As for the final signal wiring, be sure to route the audio cables down the side of the car opposite the power lines to avoid noise pick up from the lines. Also, try to route all audio cables away from noise sources such as engine computers and ABS brake computers. Proper pow

For long wire runs the wire diameter must also increase. The wire sizes noted allow for a maximum 0.5 volts DC drop over the give wire run which results in Sound Pressure Level drops inaudible to the average listener.
