The Bass Tube Difference:

Adding quality bass to your car has never been easier! With the Bazooka bass tube, installing a subwoofer becomes fast, simple, and provides excellent results. No matter what size of vehicle you have, Bazooka has a bass tube solution for you. Included in the box is a factory interface harness that is compatible with all cars. It does not matter if you have a compact Mini Cooper or a full size Chevrolet Suburban, the Bass Tube will give your vehicle low bass that it was lacking with it's factory audio system. When a subwoofer is installed, you will experience a 30% increase in your music. Bass is necessary to complete the sound stage of any listening experience. It is the subwoofer in the car's audio system that gives music its fullness and enhances the playback of each instrument's sound. For quality bass you can rely on, a Bazooka Bass Tube is exactly what you are looking for!

Bazooka Bass Tube Unique Features:

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.

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.

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.

Double Down
While this single amplified tube will surely deliver the goods, if just want more bass, simply connect a Passive Tube (sold separately) to the optional speaker level output and double your bass output.

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.

Awesome Little Subs That Need Break In Time To Shine

I have the 6250 slaved to another 6014. So, I have two 6 inch drivers sharing 275rms with a 1 farad capacitor in a completely Dynamated single cab pickup truck. 8 gauge high end wire with high end RCA's. These two subs fit perfectly with the seats all the way back. They are mounted 3 inches from the wall and face outwards (back to back) My old system was a 1000W RMS dual Aluminum DVC setup, so I do know bass. These Bazooka subs are actually dowright awesome. They do require break in time and are not too impressive right away. Your pre-outs and power source will be the key to success with these self amped subs. They like a hot signal and Bazooka even recommends using speaker level inputs over RCA's due to some Head Units with faulty claims of preout power. My head unit has a legit 4volt preout but I did have to turn the sub channel up all the way to get satisfactory power. After some break in time and time alignment tuning from the deck, I'm telling you, these two 6inch drivers can pound for their size and sound very, very professional. They are truly awesome. I'm sure you will only see great results if you set them up the way Bazooka recommends and do not skimp on connections. Get a capacitor-For Christ Sakes they cost 40 dollars and literally 5 extra minutes of your time. I'm so tired of arguing with know it alls on the internet that say they dont work and you dont need them.. They DO work and you DO need one.... Yes, the "big three" helps too but do you really wanna tear apart your factory wiring to access that? Take a look under your hood and get back to me... Anyway, sorry but thats an annoying argument. For two six inch subs to be sharing 275rms... They sound powerful and quite impressive. I'm thoroughly impressed and happy... (after break in period) These will not earth shatter boom and make your eyes cross... but they more than impressed me in both their acoustic ability up and down the ranges and..... They are surprisingly powerful, tuned, tight and full.... 5 stars for sure.

Bazooka BTA6250D Review

Great product, Fitment was a problem with recomended application. Had to use the 6" tube not the 8" that the fitment chart said would work. GMC clasic style 4 door pickup behind seat. Sounds good, a little muddy at times, most likley because it is only a 6" woofer. One problem that developed was the ignition switch after a few months did not turn off the power to the amp (INTERNAL RELAY MUST HAVE GON BAD) and thus drained the bateries on the truck when truck sat for a few days. Had to install a relay on the main power feed to compensate for this problem. Wife and I are not the hard core bass thumping crowd, but the bass adds a lot to the dynamics.

Great Product!

I would definitely recommend this sub to anyone with a car or boat in need of better sound quality. The size makes it easy to mount under a seat or dash of a boat. Excellent bass, you feel it all over the vehicle. Love this sub!

Great value

This unit fit perfect in my ford focus svt.
Bass travels throughout car and hits really nice and smooth.
Great features and I love that I could upgrade it with another bazooka speaker.

great little sub

I have had this in the rear of my 2014 Pathfinder now for three years. I bought this since it fits in the storage compartment and the 8" did not. WOW, this sub-woofer performs so well and I love my rock and dub-step. I had the 10" in my old Jeep, Bazooka makes an AWESOME product.
