5 Fuse Requirements Y ou will need to install an in-line fuse or circuit break er in the pow er wire within 18” of the batter y . This fuse or circuit break er is to protect y our v ehicle from fire in case the po wer wire shor ts to the v ehicle body .
AMPLIFIER ST A TUS LEDS The LEDs provide the f ollowing indications: 1. P ower - These LEDs illuminates the center Precision P o wer logo bac kground when the amplifier po wer is turned on. 2. Shor t - These LEDs behind the PPI logo will flash to indicate a shor t on the output.
T OOLS/P ARTS FOR INST ALLA TION NO TE: T OOLS ARE NO T SUPPLIED . Small flat b lade scre wdriver Phillips scre wdriver (#2 or medium siz ed) Wire cutters Wire strippers 4 - #6 round head scre ws, and 1 - #8 sheet metal scre w .
Note: The cables running from the battery to the rear of the car should be installed on the side of the car opposite to the antenna. When using 16 gauge wire or larger , run the speaker wires from the amplifier location through the v ehicle to the speak ers .
Note: The amplifier comes with the connector inser ted into the amplifier with the wire c lamping screws in the up position as shown belo w . Use a 2mm hex head wrenc h to secure the wires to the connector . If the connector needs to be unplug ged from the amplifier , use a 2.
wires as close together as possib le, and use the same gauge wire f or both. This will ensure that y ou ha v e a good g round path, and ma y eliminate such potential prob lems as engine noise and ov erheated amplifiers.
375W = 31.25 Amps total current dra w 12V If the same amplifier is driven into a 2 ohm stereo or 4 ohm mono load, doub le it’ s 4 ohm RMS rating. These amplifiers will eff ectiv ely doub le their pow er at this load. 250W X 1.5 X2 = 750 watts 750W = 62.
PO WER LOCK CONNECT ORS Once y ou ha v e run both the power and g round wires , then connect the cab les to the amplifier . Cut off e xcess wire, and using wire strippers, strip the ends of the power and g round cab les appro ximately 1/4 inch. Locate the Po w e r Loc k TM pow er and ground connector (supplied).

INPUTS There are two sets of RCA jac ks on the front end of y our amplifier . The RCA cab les from y our source unit go in the set labeled INPUTS . If your source unit doesn’t ha v e RCA outputs, then add a set of RCA plugs (a v ailab le at y our dealer) to y our front or rear set of speak er leads (see dra wing belo w).
QB ASS PLUS SPECIFICA TIONS Note: Not a v ailab le on the model A500/2 amplifier . QB ASS PLUS TM Up to 18dB of boost with selectab le center frequency at 30Hz, 36Hz, 44Hz or 60Hz, with a Q-f actor of 2. Optional QB ASS REMO TE TM This boost control can be mounted in the dash and will supersede the boost control on the amplifier endplate.
QB ASS PLUS/QB ASS REMO TE On A800/2 , and A1000/2 amplifiers, w e’v e tak en bass control to a higher le v el with QB ASS PLUS TM . The two QB ASS TM s witches (labeled 1 and 2) on the front end of the amplifier allow y ou to select one of f our frequency centers 30Hz, 36Hz, 44Hz and 60Hz.

ADJUSTING INPUT GAIN 1. Adjust all amplifier input gain controls to just abov e minimum sensitivity (fully countercloc kwise). 2. Using the cleanest music source (CD) pla ying, tur n up the head unit source v olume until y ou can hear distor tion. No w tur n it do wn a bit until y ou cannot hear the distor tion (usually just below full v olume).
