The Power 650 will provide 325 watts per channel (stereo) and incorporates a variable-speed fan and shroud assembly for cooling. The Power 360 provides 180 watts per channel (stereo) and i s cooled by a finned heatsink. Both the Power 650 and Power 360 offer exceptional flexibility in system design.
650 puts out 125 watts, while the 360 puts out 90. The Power 650 is rated for four 2-ohm loads, at 160 watts each or two 4-ohm loads in bridged stereo at 325 watts each. The Power 360 is not rated for 2-ohm loads, and the bridged output is two 8-ohm loads at 180 watts each.
SYSTEM FLEXIBILITY A combination of switched crossovers and four bridgeable channels in the Power 650 and Power 360 provide unmatched system flexibility with simple wiring changes. Some of the possibilities are: Biamplified Stereo - A pair of channels drives mid and high frequency speakers;...
This provides the out- of-phase drives required for bridged operation. The Power 650 and Power 360 are designed so that the four amplifier sections can be bridged in several ways. Right and Left High-Frequency channels bridged, Right High...
WHY BIAMPLIFY? For the performance. Biamplified systems can play cleanly at higher output levels than stereo systems of the same total power. the convenience. Building a satisfactory crossover system for woofer-to-midrange crossover frequencies requires large, expensive inductors and capacitors, as well as design time and mounting problems.
(Two 4-ohm speakers in parallel form a 2-ohm load.) The Power 360 is designed for a 4-ohm nominal minimum impedance on each of its four channels. In bridged mode (two amplifier channels driving a single load), each channel “sees”...
SPEAKER POWER RATINGS The Power 650 and 360 are very high-powered amplifiers, and special care must be taken to be sure that the speakers can handle the power levels. The speaker manufacturer’s recom- mendations power levels crossover frequencies should observed. Woofers with high power ratings sometimes “pop”, “clang”, “snap”, or otherwise show signs of bottoming.
Another method of taming the piezo is to insert a 1- to 10-ohm resistor in series with one of its leads. CROSSOVER SYSTEM The Power 650 and Power 360 incorporate separate high- and low-frequency crossovers, which are controlled by screwdriver- slot switches on one end of the power amplifier. The crossover...
USING THE CROSSOVERS The crossovers are usually used in biamplified mode. They separate the frequencies in the input signal into low and high frequencies separate woofer high frequency amplifiers. (See the Amplifier Block Diagram for a system layout.) When the crossovers are used for biamplified systems, the High and Low frequencies are usually set equal.

AMPLIFIER POWER WIRING The Power 650 and Power 360 battery power connections are made with heavy self-resetting wire. A circuit breaker connectors are provided with the unit. For best performance wire the amplifier exactly as described. Any resistive con- nections or voltage drops in the power wiring will result in...
Female or pre-out Connector INPUT MODE SWITCH The input of the Power 650 and Power 360 normally comes from the DIN input connector and is split by the crossovers into high and low channel drives. However, there are some cases where it is desirable to be able to drive the low channels independently.
MOUNTING THE POWER 360 The mounting position of the Power 360 will have a large effect on its ability to dissipate the heat generated in normal operation. The Power 360 has an ample heat sink for its dissipation, and internal overheating shutoff circuitry, so it is reasonably tolerant of mounting variations.

Trunk Mounting - We have measured trunk temperatures as high as 150 degrees Farenheit in the summertime. Since the thermal shutoff point for the Power 360 is 195 degrees F, it is easy to see that the amp must be mounted for maximum cooling capability.
