Bazooka Bass Tube Unique Features:

Grill
The grill is both decorative and protective, preventing the Subwoofer from accidental damage from other items, such as golf clubs, groceries or book bags that might be tossed into the cargo area where the Bazooka Woofers are typically mounted.

Woofer
Bazooka's highly efficient, customized woofers are specially designed and reinforced for use in the Bazooka Bass Tube enclosure, producing a pure piston action and generating the maximum bass output possible.

Edge Roll
All Bazooka Woofers used in Bass Tube enclosures feature large, high excursion, lightweight foam edge rolls to maximize their efficiency and overall bass output.

Tube Enclosure
A tube is a natural pressure vessel, and Bass is about pressure. The patented Bass Tube enclosure creates a natural, uniform, hydraulic transfer of the Bass energy produced by the woofer.

Port
The port opening between the Tube Enclosure and the Port Tube allows for efficient transfer of bass. Bass Tubes enclosures utilize "Bass Reflex" technology to take advantage of both the forward and backward of the woofer, wasting no bass energy.

Port Tube
The bass energy created by both the forward and backward motion of the woofer are time aligned so that 100% of the woofer's output is concentrated into one output point.

Acoustic Damping Fiber
The acoustic damping material helps lower the resonance of the enclosure and simulates an increased air space.

Integrated Amplifier
The integrated amplifiers are performance matched to the specific woofers used in Bass Tube enclosures to ensure that every watt of power is efficiently turned into bass performance. Having the amplifier integrated into the enclosure simplifies the installation and eliminates power loss.

Corner Loading
Bass Tube enclosures are specifically designed to take advantage of the natural amplification characteristics that occur when a subwoofer is placed into the corner of a vehicle. The corner acts like a megaphone, substantially increasing bass performance.

How Do I Install a Bazooka Bass Tube?

Installation is Simple! The bass tube comes with straps to keep the sub securely mounted, while still making removal quick and easy if you need even more cargo room. Optional Chrome-Plated UMS Brackets give a flashier look, as well as a more secure, permanent mounting when removal isn't a problem.

Amplifier Specifications

Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

D
Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
1 - Mono
Total RMS Power Output
Total RMS power is measured by multiplying RMS power per channel by the number of channels, and is calculated at the lowest level of operating impedance.

RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.

The RMS output figure is much more accurate than the peak rating when comparing products.

100 watts
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
16 AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
2 ohms
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Yes
Preamp Outputs
Many amplifiers are equipped with RCA preamp outputs which pass the original music signal from the source to additional amplifiers. This is known as daisy chaining because the source connects to the first amp, and the first amp connects to the second amp, etc. The advantage to daisy chaining is you only need one 2-channel RCA cable to transfer the signal from the head-unit to the amplifier, and then one additional cable for each amp being daisy chained.
No
Low-Pass Crossover Frequency
The low-pass crossover frequency is typically used for subwoofers. It can be a fixed crossover point or a variable crossover range. A variable low-pass crossover allows you to select a specific crossover point which allows frequencies below the set crossover point to pass, while making frequencies above the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

85 Hz
Subsonic Filter
Allows you to block (filter) ultra-low frequencies that your subs cannot reproduce.
39 Hz
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
105 dB
Bass/Gain Remote
If the amp comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
No
Fan Cooled
A great feature to have if an amp generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the amp from overheating (burning).
No
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
7.5A x 1 
CEA-2006 Compliant
Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
  • RMS Power
  • Signal-to-Noise Ratio

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

No

Subwoofer Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
8"
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
100 watts
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Treated Foam
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Paper Cone with Polypropylene Dust Cap
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
39 - 85 Hz

Enclosure Specifications

Box Type
Represents the style of the enclosure. Be sure to purchase the appropriate enclosure type and internal volume that will be compatible with your subwoofer's recommendation.

Sealed - Sealed boxes are those that have no holes or vents in it. The only hole in a sealed box is where the subwoofer is installed. Smaller sealed boxes require more power than a larger sealed box. They provide a tight, accurate bass, while the larger sealed enclosures provide a "boomier" and louder bass.

Ported / Vented - Ported/Vented Enclosures provide an even boomier, louder bass, but less accurate then a small, sealed box. Ported enclosures typically require more airspace per sub and also less power output from an amplifier to perform correctly.

Bandpass - Bandpass enclosures make subwoofers perform efficiently, but loose. The bass is not as "boomy" as a ported enclosure nor as punchy as a sealed enclosure. Bandpass enclosures work well with lower to mid-level subwoofers.
Vented / Ported
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
1
Box Style/Shape
The box style or shape refers to the actual shape of the box. Square and rectangular boxes are straight-edged boxes on all sides, whereas hatchback and truck style enclosures feature an angled front or back design that allows for installation in places short on depth such as single cab pickup trucks. You can also use such enclosures in hatchback cars or other vehicles where space is a premium. Tube and cylinder shaped boxes were made popular by Bazooka and are a great option for those looking for a nice amount of bass without sacrificing lots of space. They may even fit in locations that slim truck boxes cannot fit in. If the enclosure is vehicle specific, we encourage you to read the product description to find out which vehicles the enclosure is made for.
Tube/Cylinder
Height
The height of the item, measured from top to bottom, in inches.
9-7/8""
Width
The width of the item from left to right (side-to-side) measured in inches.
8-9/16""
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
18-3/8""
Number of Terminals
The number of terminals the enclosure has. Each terminal represents 1 positive and 1 negative.
Harness Connection
Terminal Type
Spring clip terminals work best with bare wire connections with small-gauge speaker wire, or pin-type connectors.

Binding post terminals are a sturdier, more versatile type of speaker terminal. Because binding post terminals are are threaded, you can tighten them down against the wire or connector for a tight, clean connection. The most popular style of binding post terminals is known as a "5-way binding post". This type can accept bare wire, or any of the common speaker wire connectors. Binding posts with the option to be used with banana clips are even more versatile

Spring posts are a hybrid of the two. Instead of using a thread and "screwing" them tight, they use a spring to allow the wire to fit and tighten against the terminal.

Molex Plug
Box Exterior Color
The color of the enclosure's exterior/outer finish.
Black
Box Finish
The material used on the outside of the box. Most boxes are carpeted to prevent exterior scratches; however vinyl is popular as it can often be color-matched to a near exact look of your leather factory interior.

Perfect Upgrade For Stock System or Aftermarket Radio Only Systems

June 10, 2009

I picked one of these up when the woofer in my 50W version of the Bazooka failed (I will replace it). Its just a bit louder as double the power (50W vs 100W) means only 3db increase, noticeable but not earth shatteringly loud.

It Does its thing, on some songs, the low, low notes are soft. This is inside a trunk (Neon SRT-4) so all bass notes are a bit muted. If I let one of the seats in the rear down, its quite a bit louder, its louder with the windows open too..

I highly recommend this for open areas like SUVs, Wagons and Hatchbacks. These things continue to surprise me with output. This will not crush your head or shake the car next too you, but will fill up your car with PLENTY of bass for basic systems. Which is why Stock Radios and Aftermarket Head Units with Stock or Aftermarket speakers powered by the head unit make a good match with a 100w Tube.

September 6, 2011

Bought this for an FJ cruiser. I love the performance. I did not and don't intend on blowing out my neighbors windows....just wanted to add some rich base to my stock system and this tube definitely does that job. I am very happy with my purchase. I would recommend this to those who share my purpose but not to those who are looking to add to a "high end" system.

If you are short on cash and need alittle bump, than this is the sub for you. This may seem like a small sub, but it hits pretty nicely. It won't produce ear shattering bass, but will definantly do the job.

I purchased this sub; to complete a high powered audio system up grade in a 36 ft. motorhome. Space was issue, for the sub was going to be installed under a couch. The Bazooka BTA8100 was a perfect fit, and with only a half volume setting, it provides room-filling bass (remember its a motorhome) !

Bazooka Bass Tube

November 5, 2011

I purchased an 8" Bass Tube by Bazooka and it was the best thing I've done for my truck audio. It enhances the bottom end greatly and you can adjust the amount of bass from woofier to tight very easily. Also, the convenience factor was huge, because my installer installed it and my new stereo deck w/ ipod input cable in less than 2 hours. I thank you Sonic Electronix for giving me the option to purchase products outside the usual B*st B*y.
Thanks again!

can I add a bass extender to this system if i am using line level inputs?
A shopper on Mar 9, 2015
Best Answer: The slave sub runs off the main sub, however the main one is powered. On the wiring harness provided by Bazooka for the main sub, locate the BROWN and YELLOW wires coming off the on the 14-pin Molex plug, the connect the BROWN wire to the RED terminal of the slave unit, and the YELLOW wire to the BLACK terminal of the passive slave unit. If the main Bazooka is powered by the high-output line levels from the head unit, the passive slave runs from the same source. You don't use RCA low-level inputs for the main sub and then power the passive slave off the high inputs from the head unit, you'll permanently damage your units. The installation instructions for your head unit will warn you NOT to use both the Low- and High-level outputs simultaneously, so don't go crazy and ignore that warning.
