Q BASS PLUS ™ POWERCLASS a higher level with switches (labeled 1 and 2) on the front end of the amplifier allow you to select one of four frequency centers - 30 Hz, 36 Hz, 44 Hz and 60 Hz. The Q SELECT switch determines the width of boosted frequencies. -

The following is a basic formula to be used as a guide to determine current draw. A 50% amplifier efficiency rating is used as an average. Your new POWERCLASS be less. This formula is to be used as a guideline. Using wire of a larger gauge can only improve the current transfer of your system. - Page 7 Before beginning, disconnect the negative (-) terminal of the battery prior to working on the positive (+) terminal to prevent a short to ground. This is important, unless you want to spend the rest of your life with a nickname like "Sparky," or "Smokey." Reconnect the negative terminal only after all connections have been made.

Page 8: Power / Ground
Grounding Locate an area near the amplifier(s) that is metal and clean an area about the size of a quarter to bare metal. Inspect the area around and underneath to be sure you won't drill into wires, brake or fuel lines, etc. Drill a pilot hole in the middle of this area. -
Page 9: Power, Ground And Remote
POWER / GROUND and REMOTE Once you have run both the power and ground wires, it's time to connect the cables to the amplifier. Cut off excess wire and, using wire strippers, strip the ends of the power and ground cables approximately 1/4 inch. -
Page 10: Speaker Wiring
Amplifier, all speaker PowerLocks plug into the amplifier with the screws facing up. Loosen the screws on the top of the blocks and insert the stripped ends of the speaker wires into the end. Double check polarity, secure each wire by tightening the screws, and plug the PowerLock connector into the amplifier with the screws on top. -
Page 11: Bridging
Deriving the mono channel is accomplished by using the left channel positive wire of the pair as the positive speaker wire and the right channel negative wire as the negative speaker wire. You should always be working with the wires of a single POWERLOCK speaker connector when bridging a pair of channels. -

Use this switch with the 4. COOLING VENTS (see page 16). 5. SPEAKER/REMOTE CONNECTOR After connecting remote and speaker wires, plug in the PowerLock connectors here (see pages 7-9). 6. -12dB For use with high level inputs (4V up to 12V). Push this switch in to attenuate the input by 12dB (see page 14). -

If you are unsure about your head unit see your local PrecisionPower dealer or call 1-800-62Power.
- Page 17 Your new POWERCLASS provide exceptional system flexibility without the added expense and installation of an outboard crossover. CHANNELS 1/2 The first row of controls on the top of your Pro6800 allow you to send a variable highpass signal (20 Hz to 20 KHz) to Channels 1/2.
- Page 18 INPUT COMBINE and GAIN Input Combine Your multi channel POWER CLASS front and rear outputs from your head unit to maintain the ability to fade front to rear, or you can run a single set of RCAs to the front inputs and push in the COMBINE switch on the amplifier end plate to route the INPUT A signal to channels 3/4 as well.
