Introduction

With the LP10, we are introducing a low-profile amplified subwoofer. Low enough to easily fit below the seat of your car, this system offers you a quick and easy way to add a high-powered subwoofer system to your audio system. The integrated amplifier in the LP10 features a low pass crossover and a subsonic filter, as well as a control for adjusting the input sensitivity from 0.2V to 6V. Both high level (speaker level) and low level (RCA type) inputs are present, making this a universal solution for use with any head unit or other input source. For further flexibility in the use of a subwoofer, a variable bass boost control has been included. You can control the subwoofer level with the remote level control module.

  • To avoid risk of electronic shock or damage to the unit, do not permit any of this equipment to become damp or wet from water or drinks. If this does occur, immediately unplug the power wires and send the product to your local dealer or service center as soon as possible.
  • If there is smoke or any peculiar odor present during use or if there is damage to any of the component enclosures, immediately unplug the power cord and send the product to your local dealer or service center as soon as possible.

SHOCK HAZARD! Do not open the case of this product. There are dangerous voltages present within the unit. There are no user-serviceable parts within the unit.

Protection Circuitry

The built-in amplifier incorporates special protection circuitry which will disable the amplifier if any of the following should occur:

  • Input overload
  • Short circuit
  • Extremely high temperatures
  1. If any of these conditions is detected, the amplifier will go into a self-preservation mode, and the PROTECT LED on the control panel will glow in RED color.
  2. What should I do if the POWER STATUS LED turns RED?
  3. If you observe that the POWER STATUS LED IS RED, please check the system carefully to determine what has caused the protection circuit to engage.
  4. To reset the amplified subwoofer when it is in PROTECT mode, turn the power off to the system (usually by turning off the head unit or other signal source that feeds the amplifier) and then turn it on again.
  5. If the internal amplifier has shut down due to thermal overload, you should first allow it to cool down before restarting.
  6. If the shutdown was due to either an input overload or a short circuit, be sure to correct these conditions before attempting to power up the subwoofer again.

Installation precautions

Before you drill or cut any holes, investigate your car’s layout very carefully. Take special care when you work near the gas tank, fuel lines, hydraulic lines and electrical wiring. Never operate the subwoofer when it is unmounted. Attach all audio system components securely within the amplifier to prevent damage, especially in an accident. Do not mount this product so that wire connections are unprotected, in a pinched condition, in contact with any metal surfaces in your vehicle, or likely to be damaged by nearby objects. Before making or breaking power connections in your system, disconnect the vehicle battery. Confirm that your head unit or other equipment is turned off while connecting the input jacks and speaker terminals. If you need to replace the power fuse, replace it only with a fuse identical to that supplied with the product. Using a fuse of a different type or rating may result in damage to your audio system or your amplifier which is not covered by the manufacturer’s warranty.

Fuses
Power fuses protect both the amplifier and the electrical system of your car from fault conditions. If you must replace a fuse in your LP10-powered subwoofer, use a fuse of exactly the same type and rating. Using a different type or rating of fuse may result in damage to your amp or vehicle or cause a fire.

Mounting the subwoofer

Find a suitable location in the vehicle in which to mount the amplifier. A typical location is shown below:

Sound Storm Laboratories LOPRO10 Amplified Car Subwoofer-Complete Features/Use Guide  & troubleshooting 3

Make sure there is sufficient air circulation around the intended mounting location. Position the subwoofer enclosure where you wish to install it. Make some small marks to identify the position and remove the unit. We have provided kits for two different installation methods, as follows:

Using self-adhesive tape

  1. Thoroughly clean the area you plan to attach the subwoofer, using a vacuum cleaner.
  2. Attach the supplied double adhesive tape, and put the subwoofer in the place and press down on it securely.

Using mounting legs

  1. Thoroughly clean the area you plan to attach the subwoofer, using a vacuum cleaner.
  2. Using the (8) machine screws provided, attach the legs to the ends of the enclosure as shown in the diagram to the right.

Connecting the subwoofer

Before doing any wiring, look through this manual and identify the diagrams to follow for power, input and speaker connections for your particular installation. Be sure you understand all the connections before you proceed.

  1. Connect the ground terminal to the closest point on the chassis of the vehicle. Keep this ground wire to less than 39″ (100 cm) in length. Use 8-gauge (or heavier) wire.
  2. Connect the remote terminal to the remote output of the head unit using 16-gauge (or heavier) wire.
  3. Connect an empty fuse holder within 18″ (45 cm) of the car battery, and run 8-gauge (or heavier) cable from this fuse to the amplifier location.
  4. Check that the fuse holder is empty. Then connect the fuse holder to the “BATT+” connection on the amplifier.
  5. Connect all line inputs and outputs (if used) using high-quality cables. Connect all speakers, following the diagrams in this manual. Be sure to observe proper polarity to avoid audio phase problems.
  6. Insert fuse(s) into the battery fuse holder(s).
  7. Recheck all connections before powering up the subwoofer.
  8. Set all level controls to minimum position, and set all crossover controls/switches to the desired frequency points.
  9. Power up the head unit and the subwoofer. Then set the volume control on the head unit to about 3/4 volume and adjust the subwoofer’s input level controls to just below the level of distortion.
  10. Further fine-tuning of the various controls may be necessary to obtain best results.

Don’t misuse the level control!

  • Do not mistake the input level control for a volume control! It is designed ONLY to match the output level of your audio source to the input level of your subwoofer.
  • Do not adjust this input level to maximum unless your input level requires it.
  • Ignoring these instructions will result in an input overload to the amplifier in the subwoofer, and excessive audio distortion. It can also cause the protection circuit to engage.Front panel controls and features

  1. REMOTE LEVEL CONTROL PORT
    Attach the included remote level control to control the volume level of the subwoofer independently.
  2. INPUT GA IN CONTROL
    After you have installed your system, turn this control to minimum Turn the head unit on (and the subwoofer will turn on via the remote connection). Turn the head unit volume to about 2/3 full level. Slowly turn up the subwoofer input gain control until you hear a small amount of distortion. Then reduce the level until the distortion is completely gone. Leave the control at this setting.
  3. SUBSONIC FILTER
    Use this control to filter out low frequency noise and rumble.
  4. BASS BOOST
    The bass boost feature will increase the sound level in the bass frequencies.
  5. LOW PASS FILTER
    This control permits you define the frequency range you want the subwoofer amplifier to receive. The subwoofer will reproduce all sound BELOW the frequency you set. If the rest of your system is weak on the mids., you may wish to set this control relatively high. If the midrange is well covered by the rest of your system, you will probably want the subwoofer to only receive lower frequency signal.
  6. PHASE SHIFT
    Use this switch to help compensate for time alignment problems in the system. Such problems usually result from having the subwoofer at a different distance from the listener than the other speakers in the system.
  7. AUTO TURN-ON SWITCH
    Placing this switch in the ON position will cause the LP10 to turn on as soon as you turn on the head unit in your car. If you wish to turn it on manually, leave this switch in the OFF position.
  8. POWER STATUS LED
    This bi-color LED glows green when power is on and no problems are present. If one of the protection circuits comes on, it will change to red.

  1. POWER TERMINALS
  2. FUSE

The fuse in the upper socket is the fuse that provides protection for the circuitry. The lower fuse is a SPARE. If a fault occurs and you need to replace the fuse, use the spare. The fuse is rated at 25A. Do not use a fuse with a different value and NEVER replace the fuse with a wire or coin.

LOW-LEVEL RCA INPUTS
Low-level inputs are the recommended way to introduce the audio signal to the subwoofer if RCA outputs are present on your head unit or other signal source (such as a sound processor).

HIGH LEVEL (speaker level) INPUTS

If your head unit does not have RCA outputs, you can use the speaker outputs for the audio source for the LP10. Use the supplied cable and wire harness and connect the outputs properly as shown in the connection diagram in this manual.

SPARE FUSE
The lower fuse socket is a storage location for a spare fuse. If the upper fuse blows, you may replace it with this fuse.

Low-Level Input Wiring
Low-level (RCA) input wiring is preferred for best audio performance. Most trunk or hatchback installations will require a 15–20-foot RCA cable, while pickup trucks and under-seat installations will require a 6–12-foot RCA cable. Always use a high-quality cable.

NOTE: Do not connect BOTH the high-level and low-level inputs from your receiver to your amplifier at the same time!

Sound Storm Laboratories LOPRO10 Amplified Car Subwoofer-Complete Features/Use Guide  & troubleshooting 7

High-Level Input Wiring

The high-level input(s) should only be used when your receiver lacks RCA outputs. If the RCA outputs are not present, connect the speaker outputs from the receiver to the high-level input connector of the amplifier. Be sure to observe polarity to avoid audio phase problems.

NOTE: Do not connect BOTH the high-level and low-level inputs from your receiver to your amplifier at the same time!
