™ QBASS PLUS Q BASS PLUS ™ On PC2400, PC2600 and PC21400 amplifiers, we've Q BASS PLUS taken bass control to a higher level with ™ Q BASS The two switches (labeled 1 and 2) on the front end of the amplifier allow you to select one of four frequency centers - 30Hz, 36Hz, 44Hz and 60Hz. -
Page 5: Installation
PC2400 60 Amp PC2600 80 Amp PC21400 160 Amp You will need to install an in-line fuse or circuit breaker in the power wire within 18" of the battery. This fuse or circuit breaker is to protect your vehicle from fire in case the power wire shorts to the vehicle body. - Page 6 WIRING 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 ™ amplifier is more efficient, other amplifiers will probably 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 WIRING 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
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. - Page 9 Insert the wires into the appropriate hole, and tighten the screws. Once the wires are secure, the PowerLock may be plugged into the amplifier. The Power/Ground PowerLock will accommodate 4 gauge wire for the PC2400 , PC2600 and PC21400 .

Page 12: Speaker Wiring
SPEAKER WIRING Using 16 gauge or larger, run the speaker wires from the amplifier location through the vehicle to the speakers. Observe the same precautions for routing these wires that you followed for running the power and remote turn-on wires. Cut off excess and, using wire strippers, strip 1/4 inch of insulation. - Page 13 INPUTS There are two sets of RCA jacks on the front end of your amplifier. The RCA cables from your head unit go in the set labeled INPUTS. If your head unit doesn't have RCA outputs don't worry. Simply add a set of RCA plugs (available at your dealer) to your front or rear set of speaker leads (see drawing below), plug them into the input jacks, and push in the -12dB input attenuation switch.
- Page 14 CROSSOVER and GAIN CONTROL C r o s s o v e r Your new POWERCLASS ™ amplifier has a 90Hz fourth-order Linkwitz-Riley type, 24dB per octave phase correlated crossover built in to provide system flexibility without the added expense and installation of an outboard crossover. The speaker outputs of your amplifier are high pass or low pass according to the HP/LP switch on the front endplate.

Page 15: Thermal Management
To manage the additional heat associated with higher output capability, a thermally controlled fan has been designed into the PC2600 and PC21400 . When the heatsink temperature reaches a pre-determined value, the fan is activated and cool air is drawn in through the lower intake vents on the endplate. -

TROUBLE SHOOTING NO SOUND Is the LED lit? Check Power and Remote turn-on wire for voltage. Make sure Ground wire is secure. STILL NO SOUND - See your Authorized PrecisionPower Dealer or call 1-800-62POWER . SOUND IN ONE CHANNEL ONLY Reverse left and right speakers by unplugging the speaker connector, turning it over and plugging it back in. -
