Introduction
With a 4-pack of Lanzar 8 Inch 1000 Watt Slim Amplified Marine Subwoofer Systems, you can take your bass-heavy beats out on the water and get the fish in the sea dancing. You may now add the bone-crushing bass you’ve always desired to your small boat or another maritime vehicle. You may place this system under your seat if necessary because its thin marine woofer works well in small spaces. This outdoor subwoofer enclosure’s marine finish and water resistance prevent rust while still allowing the music to play.
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.
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!
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!
Introduction
With the AQTB8, 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 AQTB8 features both high pass and low pass crossovers, and a control for adjusting the input sensitivity from 0.2V to 3V.
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.
What is included?
When first unpacking your new amplified subwoofer, please check first that the package contains all of the items below. If something is missing, contact the store where you purchased the product.
- AQTB8 amplified subwoofer
- Remote subwoofer level control
- Remote subwoofer control cable
- High level input wire
- Mounting hardware
Front panel controls and features
- POWER ON LED INDICATOR
- PHASE SHIFT Use this switch to help compensate for 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.
- INPUT GAIN 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
- BASS B0OST The bass boost feature will increase the sound level the bass frequencies.
- LOW PASS FILTTER 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 or you system, you will probably want the subwoofer to only receive lower frequency signal.
- REMOTE LEVEL CONTROL PORT Attach the included remote level control to control the volume level of the subwoofer independently.
- PROTECT LED INDICATOR
**
Rear panel controls and features**
- 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).
- 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 AQTB8. Use the supplied cable and connect the outputs properly as shown in the connection diagram in this manual.
- FUSE The fuse is rated at 15A. Do not use a fuse with a different value and NEVER replace the fuse with a wire or coin.
- POWER TERMINALS
Mounting the subwoofer
- Find a suitable location in the vehicle in which to mount the amplifier. A typical location is shown below:
- Make sure there is sufficient air circulation around the intended mounting location.
- 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. Then attach the supplied double adhesive tape, and put the subwoofer in the place and press down on it securely.

FREQUENTLY ASKED QUESTIONS
What does a subwoofer do for sound?****
The lower frequencies, namely 20-200 Hz, that a conventional two-channel or surround sound configuration can’t replicate on its own are delivered by the speaker. These low frequencies are produced by a variety of instruments, including the kick drum, bass guitar, pipe organ, and explosions in movies.
Which is better soundbar or subwoofer?****
You might desire a soundbar with a dedicated subwoofer if you enjoy listening to or viewing bass-heavy music genres or watching action movies. You can feel the deep thump and rumble in bass-heavy entertainment with the help of a subwoofer, which can typically offer a deeper, more powerful bass than a single bar.
How do I choose a subwoofer?****
The speaker driver is powered by the internal amplifier, which is the vital component of your subwoofer. The secret to picking a good sub is to comprehend that power, which is expressed in watts.
Is subwoofer only for bass?****
An audio loudspeaker called a subwoofer (or sub) is made to reproduce low- pitched audio frequencies called bass and sub-bass that are lower in frequency than those that can be (optimally) produced by a woofer.
Do you need speakers with a subwoofer?****
Subwoofers are speakers with big drivers that can produce low frequencies, such bass and sub-bass, effectively. As a result, subwoofers can only emit sounds between 20 Hz and 200 Hz in general. To hear the entire spectrum of frequencies, more speakers must be connected to the subwoofer.
Do subwoofers make music louder?****
In general, a more powerful subwoofer is preferred over a less powerful subwoofer because it will play louder and handle lower frequencies with greater accuracy thanks to better drive unit control.
Where should I put subwoofer?****
A subwoofer’s output can be increased by positioning it in the corner of a room, making it sound louder. A subwoofer’s fantastic feature is that it may be placed practically anyplace on your floor area, especially if it’s wireless. Finding the ideal location is not a science. And it really is a matter of personal preference.
What is the benefit of a subwoofer?****
Subwoofers enhance the clarity and bass of your stereo system. They can also improve a system’s performance in a number of different ways. A good subwoofer will give your music the depth and realism you would otherwise lose with a standard car entertainment system.
What are the 4 types of speakers?****
Traditional loudspeakers, in-wall/ceiling speakers, soundbars, and subwoofers are the four basic speaker kinds now available in homes. Each variety of speaker has a distinct function and is advantageous in certain contexts.
Do subwoofers make music better?****
A strong subwoofer makes the dynamics of the system rock harder and increases the depth and spaciousness of the soundstage. A well-matched subwoofer will significantly improve your system’s overall sound, and it will have a greater impact than replacing your electronics.
How many subwoofers do I need?****
If a home theatre uses surround sound at all, it’s common for it to employ just one subwoofer to replicate the bass frequencies. Most experts advise at least two, and some bass freaks go completely bonkers with numerous heavy-duty subs.
How do I choose a subwoofer size?****
The frequency response of the subwoofer, which is measured in Hz, shows that the deeper it will play, the larger the woofer’s surface area. The urge to choose the largest sub you can find could be strong. But size is not always a good thing.
Which AMP is best for subs?****
There are one to six channels in car stereo amplifiers. Since a mono-channel amp has a low impedance and can generate a lot of power, it is frequently the best choice for powering subwoofers.
Should Subs be louder than bass?****
If you want to have enough headroom for the rest of the song, subbass should peak at -12 dB. Keep the subbass 2 to 5 dB below the kick drum as a general rule of thumb if mixing with headroom isn’t working for you.
What happens if you use a subwoofer without an amp?****
The car subwoofer will give the automobile audio system distortion-free sound. Without an amplifier, the output from regular speakers and a subwoofer won’t typically be louder and the bass frequencies won’t be as pronounced.
Is a woofer or subwoofer better?****
A subwoofer’s primary function is to improve the audio system’s bass. It concentrates largely on low frequencies to create a deep bass impression. In actuality, the bass is far better than a typical woofer’s.
Do you need two subwoofers?****
Thus, while utilizing one subwoofer will give you more power, having two will give you a more regulated and fuller bass response. Depending on your preferred method of using your sound system, you may choose to use one subwoofer or two.
