Frequently Asked Questions - B-8PTD Sound Ordnance

How do I connect the B-8PTD subwoofer to my receiver?

Use an RCA cable from your receiver's subwoofer pre-out to the subwoofer's LFE input. Alternatively, use the speaker-level inputs if your receiver lacks a subwoofer output.

What is the recommended crossover frequency?

Start with a crossover setting of 80 Hz, then adjust based on your main speakers and room acoustics. The subwoofer has an adjustable crossover from 40 to 200 Hz.

How do I set the phase control?

Play bass-heavy content and toggle the phase switch between 0° and 180°. Choose the setting that produces the loudest and tightest bass at your listening position.

What power outlet does the subwoofer require?

It requires a standard 120V AC outlet. Make sure the power cable is securely connected and not shared with other high-power devices.

Why is my subwoofer not turning on?

Check that the power cord is plugged in, the power switch is on, and the signal sensing feature is active. If using speaker-level inputs, ensure the receiver is sending a signal.

Can I place the subwoofer in a corner?

Yes, corner placement can boost bass output, but may cause boominess. Experiment with placement 6-12 inches from walls for optimal balance.

How do I clean the subwoofer grille?

Gently vacuum the cloth grille using a brush attachment. Do not wash or use liquid cleaners. Wipe the cabinet with a dry microfiber cloth.

What is the maximum power handling of the subwoofer?

The built-in amplifier delivers 150W RMS (300W peak). Exceeding this may activate protection or cause damage. Avoid clipping by keeping the volume moderate.

Does the subwoofer have a standby mode?

Yes, it features an auto-on/off circuit. It will turn on automatically when an audio signal is detected and go into standby after a few minutes of inactivity.

What should I do if the subwoofer produces distorted sound?

Check the input levels, reduce the volume on the subwoofer, and ensure the crossover isn't set too high. Also verify that the source material has clean bass. If issue persists, consult the manual.

SAFETY INSTRUCTIONS

The product's warranty is rendered void in cases of damage resulting from failure to comply with safety and operating instructions. We do not accept any liability for consequential damages. 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 childern.
• 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

Do not use both low and high level inputs at the same time - connect only one or the other.

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 a general guideline only.

Power Wire (BAT+)

• 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 BAT+ wire from the battery to the subwoofer location. Use a grommet when running wires 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 BAT+ wire MUST be fused within 18" of the battery for protection of the vehicle's electrical system.

Ground Wire (GND)

- The subwoofer's ground wire 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 Turn-on Wire (REM)

- The remote turn-on wire connects to the head unit's amplifier turn-on lead or other switched 12-volt source.

Input Signal

• The subwoofer's input signal connects to the head unit's low level (RCA) or high level (speaker wire) outputs.
  • Dedicated subwoofer or low level inputs signal deliver the best performance. If unavailable, use the high level inputs - when interfacing with factory head unit for instance. Be sure to observe the correct polarity when using the high level inputs.

CONTROLS AND SETUP

POWER MODE(AUTO MODE)	Set the switch to AUTO MODE is your system setup doesn't have a remote wire, as with stock head units. The subwoofer will turn on automatically when it detects an incoming signal.
POWER MODE(REMOTE WIRE)	Set the switch to REMOTE WIRE is you have attached a remote turn-on lead to the subwoofer.
LEVEL	The LEVEL control (gain) is used to obtain the best possible match between the head unit audio output and the amplifier input. Begin by turning the input level control fully counterclockwise. Next, turn up the head unit volume control around 3/4 of the way up. Adjust the input level control clockwise until audible distortion is heard, then 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 control compensates for delay between the subwoofer's output and the rest of the sound system. Begin with the phase control set to 0 degrees. If the sound is adequate from the normal listening position inside the vehicle, no further adjustment is necessary. If the sound is thin or lacking bass, adjust the phase control until the bass is full and punchy.
FREQ	The FREQ is an adjustable crossover will filter out frequencies the frequency it's set for. Adjust it to where the sub's sound output blends with the rest of the sound system.
POWER	The POWER LED indicator illuminates red during normal operation.
