Fuse Requirements 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. If you are only using one amplifier, use the fuse rating indicated in this chart. If you are using more than one amplifier, add up the fuse ratings for all the amplifiers. This sum is the rating for your fuse or circuit breaker.
AMPLIFIER STATUS LEDS 1 2 The LEDs provide the following indications: 1. Power - These LEDs illuminates the center Precision Power logo background when the amplifier power is turned on. 2. Short - These LEDs behind the PPI logo will flash to indicate a short on the output. 2. Thermal - These LEDs behind the PPI logo will extinguish if the amplifier is in thermal shutdown protection. Note: Read the AP-IV Protection Circuit section for additional information regarding Short and Thermal protection.
TOOLS/PARTS FOR INSTALLATION NOTE: TOOLS ARE 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 metal screw.
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 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. Locate the speaker/remote turnon PowerLockTM connector.
Note: The amplifier comes with the connector inserted into the amplifier with the wire clamping screws in the up position as shown below. Use a 2mm hex head wrench to secure the wires to the connector. If the connector needs to be unplugged from the amplifier, use a 2.5mm hex head wrench to remove the retaining screw from the connector (set aside and save the retaining screw). The two negative outputs are common to each other as are the two positive outputs. A speaker may be connected to either terminal.
wires as close together as possible, and use the same gauge wire for both. This will ensure that you have a good ground path, and may eliminate such potential problems as engine noise and overheated amplifiers. CHARGING SYSTEM If your total current draw is over 100 amps (or total output power is over 600 watts), you are probably exceeding the capability of your charging system. Dimming lights and fluctuating voltage are solid indicators that you need to upgrade your alternator, battery, or both.
1300W = 108 Amps total current draw 12V If the same amplifier is driven into a 2 ohm load, double it’s 4 ohm RMS rating. These amplifiers will effectively double their power at this load. 1000W X 1.3 X 2 = 2600 watts 2600W = 217 Amps total current draw 12V If you are using more than one amplifier, add up the total current draw for all of them and choose the appropriate gauge based on the grand total.
POWERLOCK CONNECTORS Once you have run both the power and ground wires, then 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. Locate the PowerLockTM power and ground connector (supplied). Using a hex wrench, loosen the screws before attempting to insert the cable wires. Insert the wires into the appropriate hole, and tighten the screws.

This button pushed ‘IN’ must be used for speaker level input on common ground head-units or for high voltage line drivers. 13. Phase: These switch sets the phase of the output relative to the amplifier input. 14. RCA Outputs: RCA outputs provide HP/LP/FULL 30-4kHz signal to another amplifier.
4. Cooling Plenums: Maintain a minimum 2” clearance around cooling plenums for proper amplifier cooling. INPUTS There are two sets of RCA jacks on the front end of your amplifier. The RCA cables from your source unit go in the set labeled INPUTS. If your source unit doesn’t have RCA outputs, then 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.
QBASS PLUS SPECIFICATIONS QBASS PLUSTM Up to 18dB of boost with selectable center frequency at 30Hz, 36Hz, 44Hz or 60Hz, with a Q-factor of 2. Optional QBASS REMOTETM This boost control can be mounted in the dash and will supersede the boost control on the amplifier endplate.
QBASS PLUS/QBASS REMOTE On these amplifiers, we’ve taken bass control to a higher level with QBASS PLUSTM. The two QBASSTM 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. On the rear end plate you will find the QBASSTM level control and plug-in for an optional QBASS REMOTETM dash mounted level control. Adjust the level control clockwise for up to +18dB of boost at your selected frequency. QBASSTM Settings 1 2 Freq.
TC-X CROSSOVER Your new amplifier has a TC-X Crossover (Total Control X-over®) 30Hz-4kHz (see this guide for Crossover Chart).12dB per octave phase correlated crossover built-in to provide superior system flexibility without the added expense and installation of an outboard crossover. The speaker outputs of your amplifier are high pass, low pass, or all-pass according to the HP/LP/FULL switch on the front endplate.

ADJUSTING INPUT GAIN 1. Adjust all amplifier input gain controls to just above minimum sensitivity (fully counterclockwise). 2. Using the cleanest music source (CD) playing, turn up the head unit source volume until you can hear distortion. Now turn it down a bit until you cannot hear the distortion (usually just below full volume). 3. Increase the amplifier gain (clockwise) until the onset of audible distortion. Then decrease the gain to the point just before the distortion starts.
NO SOUND Is the LED illuminated? YES NO Check Power and Remote turn-on wire for voltage. Make sure the ground wire is secure. STILL NO SOUND See your Authorized Precision PowerTM Dealer or call 1-800-62POWER. SOUND IN ONE CHANNEL ONLY Reverse the left and right speakers by unplugging the speaker connector, turning it over and plugging it back in. SOUND IS NOW IN OPPOSITE CHANNEL SAME CHANNEL Reverse RCA inputs. Problem is in the speaker or speaker wire of the silent channel.
