specifications about this manual amplifier section To get the most from your a/d/s/ PowerPlate TM, we recommend that you have the installation performed by your qualified authorized a/d/s/ dealer. If this unit is installed by your dealer, we will extend the warranty to three years instead of the standard one year. However, if you feel that you have the necessary skills and prefer to perform the installation yourself, this manual will guide you through the process of installation and set-up.

P450 system diagrams System 1 - P450 used in 4-channel mode with front and rear full range speakers. System 2 - P450 used in 2-channel bridged mode with full range speakers.
System 3 - Two P450’s; one is used to drive front tweeters and midrange drivers, the second is used in 2-channel bridged mode for subwoofers. Subwoofer level can be controlled by using the source’s front output for the first P450 and the rear output for the second P450.
System 1 – P650 used in 6-channel mode. Channels 1/2 are high-passed for front speakers. Channels 3/4 are high-passed for rear speakers. Channels 5/6 are low-passed for subwoofers. Although shown with 4-channels of input, the source unit can be either 2- or 4-channel. System 2 – P650 used in 6-channel mode. Channels 1/2 are high-passed for front speakers. Channels 3/4 are high-passed for midrange speakers, and channels 5/6 are low-passed for subwoofers.
adjusting input sensitivity System 3 – P650 used in 3-channel mode. Channels 1/2 and 3/4 are high-passed and bridged for front speakers. Channels 5/6 are low-passed and bridged for a single subwoofer. The input sensitivity setting is important to ensure proper performance, low noise levels, and maximum system reliability.
P850 system diagrams Using the AC502 (optional) System 1 – P850 used in 6-channel mode. Channels 1/2 are high-passed for front speakers channels 3/4 are high-passed for rear speakers, and channels 5/6 and 7/8 are bridged low-pass for subwoofers. Although shown with 4-channels of input, the source unit can be either 2- or 4-channel. The AC502 remote level control, available as an accessory from your a/d/s/ dealer, may be used with your PowerPlate™ to remotely adjust the level of your subwoofer.
xover control 5/6 (P650) – The crossover selection for channels 5&6 has three possibilities: System 3 – The P850 is used in fully active 8-channel mode. Channels 1/2 are high-passed for front tweeters. Channels 3/4 are bandpassed for front midrange. Channels 5/6 are bandpassed for front midbass. Channels 7/8 are low-passed for subwoofers. The P850 is configured for 2-channel input. Note: Optional AC502 can be used in this system to adjust the level of the subwoofers.
installation 1. Disconnect the battery ground cable. Reconnect the ground cable only after the installation is complete and the wiring has been checked to make sure that there are no problems. If your radio features a code type security system, be sure you know the code before disconnecting the battery! 2. Run a minimum AWG #8 power wire directly from the battery to the PowerPlate™ mounting location.
internal signal routing, cont’d Channels 5/6 input switch (P650 and P850) – selects input from three possibilities. When the switch is in the left position, channels 5/6 receive input from the 5/6 DIN inputs. When the switch is in the center position, channels 5/6 receive input from channels 1/2 RCA input. When the switch is in the right position, channels 5/6 receive input from a summed input of channels 1, 2, 3, and 4 RCA input. Channel 5 receives the summed input of channels 1 and 3.
signal sources Due to the wide input level adjustment range, all a/d/s/ PowerPlatesTM can be driven with either a conventional preamplifier drive signal or the amplified signal from a powered source unit. This makes the PowerPlate TM perfect for upgrading an OEM (Original Equipment Manufacturer) stereo system while retaining the factory installed radio. Because of the high impedance of the a/d/s/ input stage, the factory radio drives an easy load.
