Introduction

With the PLMRSBA8, 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 PLMRSBA8 features low pass crossovers and control for adjusting the input sensitivity from 0.12V to 3.5V. 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.

Mounting the Subwoofer

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

  2. Make sure there is sufficient air circulation around the intended mounting location.
  3. Mark the location for mounting hole screws by positioning the cabinet where you wish to install it. Make a small mark to identify the position and remove the unit. Thoroughly clean the area you plan to attach the subwoofer, using a vacuum cleaner, and press down on it securely.

Control Panel and Features

8-Inch-Low-Profile-Amplified-Subwoofer-System-600-Watt-Compact-Enclosed-Active-Underseat-Car-Audio-Subwoofer-Fig-2

  1. POWER ON LED INDICATOR
  2. PROTECT LED INDICATOR
  3. 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.
  4. AUTO POWER ON
    In OFF mode, It’s not necessary to connect the remote cable if you’re using the high-level inputs. Do not function with the RCA inputs. However, we prefer the direct remote wiring on a “plus after contact”.
  5. LOW PASS FILTER
     This control permits you to define the frequency range you want the subwoofer amplifier to receive. The subwoofer will reproduce all sounds 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 a lower frequency signal.
  6. BASS BOOST
     The bass boost feature will increase the sound level of the bass frequencies.
  7. INPUT GAIN CONTROL
    After you have installed your system, turn this control to a 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 and 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.
  8. REMOTE LEVEL CONTROL PORT
     Attach the included remote level control to control the volume level of the subwoofer independently.
  9. 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 PLMRSBA8. Use the supplied cable and connect the outputs properly as shown in the connection diagram in this manual.
  10. 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 another signal source (such as a sound processor).
  11. FUSE
    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.
  12. POWER TERMINALS 

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 trunks 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.

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.

Power Connections

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. Connect the remote terminal to the remote output of the head unit using 16 gauge (or heavier) wire. 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. Then connect the fuse holder to the “BATT+” connection on the subwoofer rear panel.

Remote Level Control Connection

Frequently Asked Questions

Why doesn’t my powered subwoofer function?

Checking the fuse should be your first step if your subwoofer stops working. Replace it if it is blown and check to see if the issue is resolved. If it doesn’t, there can be another issue with the subwoofer, in which case you’ll need to have an expert fix it.

Why isn’t my subwoofer making as much noise as it should?

Your subwoofer’s failure to produce powerful bass can be attributed to a variety of factors. You’re not giving it enough power is one of the most frequent causes. Other potential problems include a defective head unit or a grounding issue.

Is it acceptable to leave the subwoofer on constantly?

You don’t have to switch it off after every use, though. It won’t harm anything if you leave it on, but you can turn it off if you like. There was a problem, I apologise.

My subwoofer keeps turning on and off. Why?

If there is no signal after a certain amount of time, the subwoofer may include an energy-saving mode that turns the amplifier off. To prevent the subwoofer from shutting off on its own in this situation, put the Power Save switch to the OFF position.

How can I tell if my subwoofer is functioning?

To determine whether your sub has blown, test the sound at a low volume. You have a partially blown subwoofer if the sound is distorted, and a fully blown subwoofer if there is no sound at all. Before jumping to conclusions, check the cable if the subwoofer is receiving its signal through one.

How can I make my subwoofer’s bass stronger?

Your subwoofer should be positioned facing outward into the rest of the room and within 8–12 inches of a wall for the best sound quality. Consider locating your subwoofer in the room’s corner for even greater output, since this placement can greatly improve the overall sound.

Do I require a unique cable for my subwoofer?

There isn’t a special kind of audio cable needed for subwoofers. The audio input jacks integrated into the subwoofer itself will determine the specific kind of cable required to connect a subwoofer to an audio system.

Do subwoofers function at low volume levels?

Most individuals are fortunate to hear much lower 30HZ because the human ear can only hear down to about 20HZ. Most movie and music soundtracks sound more realistic even at very low volume levels because subwoofers that can reach the lowest octaves enable us to feel the bass that we typically can’t hear.

Do Pyle power Subs work well?

I have owned and managed many subwoofers over the years, but these are the best. They have my utmost satisfaction. If I could find room in my car for some, I would buy them again ten out of ten times. 5 stars overall exceeded expectations in a big way!

How is the gain on a powered subwoofer adjusted?

Set the gain on your sub amp to the lowest, most anticlockwise setting. Turn on the low-pass filter and adjust the clockwise setting to the maximum height. Turn off the bass boost if it has one.
