CAUTION!
The extended use of a high powered audio system may result in hearing loss
or damage. While PPI systems are capable of "Concert Level" volumes,
they are also designed for you to enjoy at more reasonable levels all of the
creative expressions made by musicians. Please stay seated while driving
and observe all local sound ordinances.

- Page 8 All PPI amplifiers are capable of being bridged into a 4-Ohm mono output without switches or bridging modules. This in turn allows you to run Full range or component speakers and a subwoofer off one PPI amplifier. (using passive crossovers) You can achieve this mono channel by using the Left positive (+) speaker connection and Right negative (-) speaker connection.
