Frequently Asked Questions - B-10AS Sound Ordnance

How do I wire the B-10AS with a factory radio?

Use the included high-level adapters to tap into your factory speaker wiring. Connect the adapters to the gray (left positive), green (right positive), and corresponding negative wires. Leave the blue/white remote bullet connectors joined so the subwoofer auto-turns on when it senses the signal.

How do I connect the subwoofer to an aftermarket receiver?

Disconnect the bullet connectors on the blue/white wire. Connect the male bullet (Remote In) to your receiver's remote output. Use RCA cables from the receiver's subwoofer output to the subwoofer's RCA inputs. Ensure a good ground and fused power connection.

Why is the PROTECT LED red and the subwoofer not working?

The red PROTECT LED indicates a fault: over/under voltage, overheating, or a short circuit. Check your power and ground connections, ensure the battery voltage is 11-16 V DC, let the unit cool down, and inspect wiring for shorts. Blown fuses can also trigger protection.

What size fuse does the B-10AS require and where should it be placed?

The subwoofer uses a single 10 A fuse. For safety, install an additional in-line fuse holder within 18 inches of the battery positive terminal, also rated 10-30 A (use 10 A to match). This protects the vehicle's electrical system.

How do I adjust the GAIN control properly?

Set the GAIN fully counterclockwise. Turn your receiver's volume to about 3/4 of maximum. Play music with strong bass. Slowly turn the GAIN clockwise until you hear distortion (buzzing or scratchy sound), then back off slightly counterclockwise. This achieves the best signal match without distortion.

What does the BASS EQ control do?

The BASS EQ boosts or cuts the bass level at 60 Hz from 0 to +12 dB. Start at 0 dB and increase gradually to match your preference. Avoid excessive boost to prevent distortion or damage.

How do I set the PHASE switch?

The PHASE switch (0° or 180°) compensates for timing differences between the subwoofer and other speakers. Play music with consistent bass and toggle the switch. Use the position where the bass sounds fullest and most integrated.

Why is the bass weak or lacking impact?

Weak bass can be caused by incorrect phase setting (try flipping the phase switch), low input signal (check connections and GAIN), or a crossover set too low. Also ensure the subwoofer is not wired out of phase (polarity reversed). Adjust the crossover and phase accordingly.

Can I install the B-10AS in a home audio system?

No, this subwoofer is designed for 12 V DC negative ground automotive systems only. Connecting to a home AC outlet will damage the unit and create a safety hazard.

How do I troubleshoot engine noise (alternator whine)?

Engine noise is often due to a poor ground connection. Ensure the subwoofer's ground wire is attached to clean, unpainted bare metal. Re-route RCA cables away from power wires and other high-current wiring. Use a ground loop isolator if necessary.

We do not accept any liability for personal injury or damage to property caused by incorrect handling of the device or failure to observe the safety and operating instructions. In such cases the warranty is rendered void.

High volume levels can cause hearing damage or loss. Use care when setting the volume of your subwoofer. Obey any local noise laws or ordinances.

To prevent injury or damage to your powered subwoofer, please read and follow the instructions in the manual.

If you're not confident about installing your powered subwoofer, call us at 1-800-955-9094.

Disconnect the cable to your car battery's negative terminal before starting the installation.

• For safety reasons, do not attempt to modify the subwoofer.
• Only a 12V DC car supply system (negative ground) should be used. Never connect the subwoofer to any other voltage supply.
• Extra care should be taken when first turning on the amplifier after installation. Please follow the operating instructions carefully.

• Keep water and other liquids away from the vicinity of the powered subwoofer. This could result in a fire or a fatal electrical shock. If liquids get into the subwoofer, immediately disconnect the power to the subwoofer.

• Do not expose the subwoofer to high temperatures, strong vibrations or heavy loads.

• Do not leave packaging material unattended around children.
• Observe the safety and operating instructions of this subwoofer and any other devices connected to the subwoofer.
• Disconnect the negative battery terminal to your car battery before beginning installation. Some vehicles may require a reset after this. Consult with your car dealer or mechanic.

SETUP AND INSTALLATION

To ensure proper operation, please read these instructions carefully before installing and using this powered subwoofer.

These installation instructions do not cover all possible installation issues. If you're not confident about installing your powered subwoofer, call us at 1-800-955-9094.

1. Read and understand the instructions before attempting to install this powered subwoofer.
2. Disconnect the negative terminal from the battery prior to starting the installation. Disconnecting the negative terminal on some vehicles may result in safety equipment becoming disabled. Consult with your car dealer or mechanic if you have any questions or concerns.

3. For the best possible sound, use high-quality connectors and wiring.

4. Exercise caution before doing any drilling or cutting in your car. Be careful of fuel lines, electrical wiring, vacuum lines, or fuel tanks in your vehicle.

5. Never run power or speaker wires underneath your vehicle. Protect the wires by keeping them inside the vehicle.
   6 Avoid running power or speaker wires over, near, or through sharp-edged surfaces. Use rubber grommets to protect wires running through openings in metal.

CONNECTIONS

Never run any wires underneath or outside the vehicle.

NOTE: Be sure to follow specific instructions included with your amplifier installation kit (not included with this powered subwoofer). The information below should be used as a general guideline only.

Power Wire (BATT+)

• Disconnect the negative battery terminal before proceeding. Call 1-800-955-9094 for instructions if you are unsure.
• Plan wire routing before cutting any wires to length. Begin by routing the power BATT+ wire (10 AWG) from the battery to the subwoofer location. Use a grommet when running wire through the firewall or metal openings. Avoid running the power wire near existing vehicle wiring to prevent induced noise from entering the audio system.
  • Exercise caution when drilling holes to avoid damaging fuel lines or existing vehicle wiring.
• The BATT+ wire MUST be fused (10-30 A) within 18" of the battery for protection of the vehicle's electrical system.

Ground Wire (GND)

- The subwoofer's ground wire (10 AWG) should be as short as possible. Choose a clean unpainted

section of metal or the vehicle chassis when attaching the ground connection. Be sure to clean the area of any dirt or grease.

Remote and input with a factory radio

- If you are installing your B-10AS in a system with a factory radio, leave the Remote In/Out bullet connectors on the blue/white wire together, and the subwoofer will turn itself on when it senses the high-level signal on its input. Use the included speaker-level adapters to tap into the factory speaker wiring for signal.

Installing with an aftermarket receiver

- If you're using line-level RCA signals from an aftermarket receiver, disconnect the bullet connectors and wire the male bullet connector, labeled Remote In, to your receiver's remote output. Connect the subwoofer's input to the receiver's output with RCA cables. If your receiver has dedicated subwoofer outputs, use them.

CONTROLS AND SETUP

GAIN	The GAIN control is used to obtain the best possible match between the receiver's audio output and the subwoofer input. Begin by turning the input level control fully counterclockwise. Next, turn up the receiver's volume control around 3/4 of the way up. Adjust the GAIN control clockwise until audible distortion (buzzing or scratching) is heard, then back slightly counterclockwise to provide the best match.
BASS EQ	The BASS EQ lets you boost or attenuate the bass level to match your listening preference. Set the BASS EQ at 0dB to start, and increase the level for stronger bass.
PHASE	The PHASE switch compensates for delay between the subwoofer's output and the rest of the sound system. Set the PHASE switch to whichever position the bass sounds fullest.
CROSSOVER	The CROSSOVER is an adjustable low-pass filter that cuts out frequencies above the point it's set for. Adjust it to where the subwoofer's bass sound blends with the rest of the speaker system.
POWER	The POWER LED indicator illuminates green during normal operation.
PROTECT	The PROTECT LED indicator illuminates red when the subwoofer automatically protects itself from over-or under-voltage, overheating, and short circuits.
REMOTE LEVEL	Connect the REMOTE LEVEL control to attenuate, turn down the subwoofer volume remotely.
