Mounting hardware

Quick-start guide

IMPORTANT: Disconnect the vehicle’s negative (-) battery terminal before beginning the installation.

Always wear protective eyewear when using tools.

Choose a safe mounting location, away from moisture. Check clearances on both sides of a planned mounting surface. Be sure that screws or wires will not puncture brake lines, fuel lines, or wiring harnesses and that wire routing will not interfere with the safe vehicle operation. Use caution when drilling or cutting in the mounting area.

When making electrical connections, make sure they are secure and properly insulated.

If you must replace any of the amplifier’s fuses, use the same type of fuse and current rating as the original.

To keep the amplifier cool, choose a location that provides enough air circulation, such as under a seat or in the trunk.

Do not mount the amplifier with the heat sink facing downward, as this interferes with cooling.

Mount the amplifier so that it will not be damaged by the feet of backseat passengers or shifting cargo in the trunk, and so that it remains dry.

1. Choose a safe mounting location ensuring adequate air circulation and protection from damage.

2. Using the amplifier as a template, mark the locations of the holes on the mounting surface.

3. Drill pilot holes in the mounting surface.

4. Attach the amplifier to the mounting surface with four appropriate mounting screws (not included). Recommended: #8 Phillips-head sheet metal screws.

NOTE: You may find it more convenient to make all of the connections to the amplifier before you permanently mount it.

Power (+12V): Run power wire from the +12V input on the amplifier to the positive terminal of the vehicle’s battery. Insert bare wire into the terminal on the amplifier, then tighten the setscrew with a Phillips screwdriver.

Install an appropriate fuse holder and fuse within 18″ (457mm) of the battery. Fuse requirements: 20A minimum for Primus 6002a, 30A minimum for Primus 6004a and 3000a, and 40A minimum for 9004a.

Make sure the wire is not damaged or pinched during installation. Install protective grommets when routing wires through the bulkhead or other sheet metal.

Minimum wire size: ≥10 gauge for Primus 6002a; ≥8 gauge for Primus 6004a, 9004a, 3000a. Use larger-gauge wiring for longer runs.

Ground (GND): Run a wire (the same gauge as the power wire) from the GND input on the amplifier to a factory bolt in the vehicle’s chassis. NOTE: Remove any paint from the chassis for best contact. Use a star washer below the ring connector for a secure connection.

Connect a 20-gauge wire from the “Remote Out” lead of the source unit to the REM input on the amplifier. This lead turns the amplifier on when using low-level input signals. If your stereo has no “Remote Out” lead, connect the amplifier’s REM input to switched accessory power.

The light will illuminate in blue when the amp is receiving power and playing. The indicator will illuminate in red if the amp enters Protect mode in the event of conditions such as over/under voltage, short circuit, amplifier output circuit failure, or excessive heat.

Replace only with fuses of the same amperage:

Primus 6002a: 20A

Primus 6004a and 3000a: 15A x 2

Primus 9004a: 20A x 2

Connect speakers observing proper polarity (+ to +, – to -).

2-channel operation: Connect the left speaker to the L+ and L- terminals, and the right speaker to the R+ and R- terminals.

Bridged operation: Connect the positive wire from the single speaker or subwoofer to the R+ terminal, and the negative wire from the speaker or subwoofer to the L- terminal.

Connect speakers observing proper polarity (+ to +, – to -).

4-channel operation: Connect the front left speaker to Channel 1 (+/-), front right speaker to Channel 2 (+/-), rear left speaker to Channel 3 (+/-), and rear right speaker to Channel 4 (+/-).

3-channel operation: Connect stereo speakers to Channel 1 (+/-) and Channel 2 (+/-) as described above. Connect the single speaker’s positive (+) lead to the Channel 3 + terminal, and the negative (-) lead to the Channel 4 – terminal.

2-channel (bridged) operation: Connect one speaker’s positive (+) lead to the Channel 1 + terminal, and the negative (-) lead to the Channel 2 – terminal. Connect the other speaker’s positive (+) lead to the Channel 3 + terminal, and the negative (-) lead to the Channel 4 – terminal.

NOTE: Minimum speaker impedance for stereo full-range and subwoofer operation is 2 ohms. Minimum speaker impedance for bridged operation is 4 ohms.

The Primus 3000a features positive (+) and negative (-) terminals.

Single Subwoofer: Connect the subwoofer’s positive (+) wire to the positive (+) terminal, and the subwoofer’s negative (-) wire to the negative (-) terminal.

Two Subwoofers (Parallel): Connect one sub’s positive (+) and negative (-) leads to the positive and negative terminals of the other sub. Then connect that subwoofer’s positive (+) wire to the amplifier’s positive (+) terminal, and the subwoofer’s negative (-) wire to the amplifier’s negative (-) terminal.

NOTE: Minimum speaker impedance is 2 ohms.

If your source unit offers preamp outputs, connect to the L and R (6002a and 3000a), or CH1, CH2, CH3, and CH4 (6004a and 9004a) inputs using RCA patch cables.

If your car audio system’s head unit does not have line-level outputs:

1. Connect the white, white/black, gray, and gray/black wires of the included high-level input harness(es) to the front and/or rear speaker output wires of your car audio system’s head unit (splice crimps not included).

2. Connect the black wire of the harness to vehicle chassis ground.

3. Plug the high-level harness into the Primus amplifier’s high-level input.

Important: Some factory-installed audio system amplifiers include electronic filters that limit bass sent to smaller speakers. This filtering will adversely affect the Primus amp’s performance. To get the most bass possible, splice the high-level harness into the factory system speaker outputs connected to the system’s largest speakers (those designed to reproduce the most bass).

To match your amplifier’s input sensitivity (gain) to your source unit’s output level, follow this procedure:

A. Turn both input level controls counterclockwise to MIN (minimum).

B. Play a dynamic music track through your source unit. Turn the source unit’s volume control to the 3/4 position.

C. Turn the front input level control dial clockwise towards MAX until you hear distortion in the music (it’s no longer clear).

D. Slowly turn the front level input control dial counterclockwise until the music sounds clear again.

E. Your front input level is now correctly set. Repeat this process with the rear channels (if applicable).

Use the slider controls to select the crossover filter for your system (the Primus 3000a filter is low-pass only).

LPF (Low Pass): Choose this setting if you’re connecting a subwoofer(s), or want to provide a low-pass filter for separate mid-bass speakers.

FULL (Full Range): Choose this setting if you’re connecting full-range speakers, and not using a subwoofer in your system.

HPF (High Pass): Choose this setting to prevent low bass from reaching midrange or full-range speakers when you’re using a subwoofer in your system.

Turn the crossover frequency control dials to the left to lower the crossover point, and to the right to raise the crossover point. Adjust the crossover point settings for speakers and subwoofers to suit listener preference. Exact crossover settings depend on your listening preferences. NOTE: Crossover point does not apply in FULL mode.

You can increase the bass output of your system with the Bass EQ feature up to +12dB.

Turn the LEVEL dials to the right to increase the bass output.

The Primus 3000a also lets you choose the center frequency of the bass boost – the frequency that receives the most boost effect.

Turn the FREQ dial to the right to adjust the center frequency (between 40Hz and 100Hz). The frequency you choose depends on your listening preferences.

You can choose a subwoofer phase output of 0° or 180°. To check your sub’s phase, play music with lots of bass and listen as another person slowly turns the dial back and forth between 0 and 180 degrees. The correct setting is the one that gives you more bass. If you don’t detect any real difference, leave the dial in the 0° setting.

Cause: No voltage at BATT+ and/or REM terminals, or bad or no ground connection. Solution: Check voltages at amplifier terminals with VOM (Volt Ohm Meter).

Cause: DC voltage on amplifier output. Solution: Amplifier may need service; see enclosed warranty card for service information.

Cause: Amplifier is overheated. Solution: Make sure amplifier cooling is not blocked at mounting location. Verify that speaker-system impedance is within specified limits. Or, there may be voltage greater than 16V (or less than 8.5V) on BATT+ connection. Check vehicle charging system.

Cause: Voltage less than 9V on BATT+ connection. Solution: Check vehicle charging system.

Cause: Gain is not set properly. Short circuits or grounds on speaker wires. Amplifier or source unit may be defective. Solution: Check INPUT LEVEL setting. Check speaker wires for shorts or grounds.

Cause: Short circuit in speaker or wire. Solution: Remove speaker leads one at a time to locate shorted speaker or wire, and repair.

Cause: Speakers are not connected properly. Solution: Check speaker connections for proper polarity.

Cause: The wiring is connected incorrectly or there is a short circuit. Solution: Review installation precautions and procedures. Check wiring connections.

Cause: Amplifier is picking up alternator noise. Loose or improper ground connection. Solution: Turn down gain. Move audio cables away from power wires. Install an alternator noise filter on power line between battery and alternator. Check ground connections on the amplifier.
