3 QB ASS ™ Q B ASS ™ On the PC1400 amplifier , we offer tremendous control of your bass with Q B ASS ™ . On the front end panel of your PC1400 y ou will find the Q B ASS ™ le v el control. Adjust the level control clockwise for up to 12dB of boost at a factory preset frequency of 40Hz.
4 QB ASS PLUS ™ Q B ASS PLUS ™ On the PC1800 amplifier , we'v e taken bass control to a higher le v el with Q B ASS PLUS ™ . The two Q B ASS switches (labeled 1 and 2) on the front end of the amplifier allow you to select one of four frequency centers 30Hz, 36Hz, 44 Hz and 60 Hz.
5 T ools/P arts needed for Installation (not supplied) Small flat blade screwdriver Phillips Screwdriver (#2 or medium sized) Wire cutters Wire strippers 4 - #6 round head screws, and 1 - #8 sheet met.
The following is a basic formula to be used as a guide to determine current dra w . A 50% amplifier efficiency rating is used as an a verage . Y our new PO WER CLASS ™ amplifier is more efficient, other amplifiers will probab ly be less. This f or mula is to be used as a guideline .
Before beginning, disconnect the negative (-) terminal of the battery prior to working on the positive (+) terminal to prevent a shor t to ground. This is impor tant, unless y ou want to spend the rest of your lif e with a nic kname lik e "Sparky ," or "Smoke y .
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.
9 PO WER / GR OUND and REMO TE Once you have run both the power and ground wires, it's time to connect the cab les to the amplifier . Cut off e xcess wire and, using wire strippers, strip the ends of the power and ground cab les appro ximately 1/4 inch.
10 1. INPUTS Plug in the RCA leads from your head unit or crossover here (see page 13). 2. GAIN Use this control to match the output level of the head unit to the amplifier (see page 15). 3. -12dB For use with high level inputs (4V up to 12V). Push this switch in to attenuate the input by 12dB (see page 13).
1. INPUTS Plug in the RCA leads from your head unit or crossover here (see page 13). 2. GAIN Use this control to match the output level of the head unit to the amplifier (see page 15). 3. SUBSONIC FREQ. This is used to control the detented subsonic filter from 5Hz to 50Hz (see pages 15 & 16 ).
12 SPEAKER WIRING Using 14 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. Locate the speaker/remote tur n-on P ower Lock connector .
There is a pair of RCA inputs on the front end of y our amplifier . The RCA cables from your head unit or crossover plug in here. If y our head unit doesn't hav e RCA outputs don't worr y .
14 Heatsink Cooling The unique heatsink on your PO WER CLASS ™ amplifier has been designed with fins on the inside of the aluminum mass. This allows f or the transfer of heat from the circuitry to the heatsink fins and out through the vents in the endplates.
15 Crosso ver PC-1400 Y our new Monobloc k amplifier has a variab le 20-5kHz 12dB/Octav e HP/ LP crossov er . When y ou select the LP f eature on this amplifier you ha v e made the output RCA's HP , and vice versa when y ou select HP f or the speaker output.
