Frequently Asked Questions - B-8P Sound Ordnance

How do I connect the subwoofer to a factory stereo without RCA outputs?

Use the high level inputs (speaker wire) provided. Connect the speaker outputs from your factory stereo to the high level input harness, observing correct polarity. Do not use both low and high level inputs simultaneously.

What is the difference between Auto Mode and Remote Wire mode?

In Auto Mode, the subwoofer turns on automatically when it detects an incoming audio signal, ideal for factory head units without a remote wire. In Remote Wire mode, it turns on when 12V DC is applied to the remote turn-on lead, giving you direct control from an aftermarket head unit.

How do I adjust the phase control?

Start with the phase control set to 0 degrees. Listen from the normal listening position. If bass sounds weak or thin, adjust the phase control gradually until the bass becomes full and punchy. This compensates for any delay between the subwoofer and the rest of the system.

My subwoofer won't turn on (no power LED). What should I check?

First, check that the BAT+ wire has 11-16VDC, the REM wire (if used) has 12V, and the GND wire is securely connected to clean bare metal. If all connections are good, inspect the fuse and replace if blown.

Why is there engine noise?

Engine noise is typically caused by a bad ground connection or a signal ground loop. Ensure the subwoofer's ground is attached to clean, unpainted metal. Also, reroute RCA cables away from high-current wiring to reduce radio frequency interference.

How do I set the gain (LEVEL control) correctly?

Turn the LEVEL control fully counterclockwise. Set your head unit volume to about 3/4 of its maximum. Slowly turn the LEVEL control clockwise until you hear audible distortion, then turn it back slightly counterclockwise. This matches the head unit output to the subwoofer input.

What is the recommended fuse rating for the B-8P?

The subwoofer uses a single 7.5 amp fuse. Always replace with the same rating to avoid damage. The power wire should also have a fuse within 18 inches of the battery, sized according to your installation kit.

Can I use both low level (RCA) and high level inputs at the same time?

No, do not connect both input types simultaneously. Use only one type: either low level RCA outputs from an aftermarket head unit, or high level speaker wire inputs from a factory stereo.

What are the dimensions of the B-8P subwoofer?

The dimensions are: Width 14.875 inches (377.83 mm), Height 11.13 inches (282.58 mm), Depth 1 14.875 inches (377.83 mm), Depth 2 10.125 inches (257.18 mm). Depth 2 likely refers to mounting depth or depth with grille.

Does the Sound Ordnance B-8P come with a warranty?

Yes, it comes with a 3-year limited warranty covering parts and labor, valid only in the USA and Canada. The warranty applies to the original purchaser from an authorized dealer. Proof of purchase is required for service.

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.

B-8P/B-8PT

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.
