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.

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.

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.

Nice Add-On

I recently added this unit to my extended cab pickup. It works fairly well but it's missing one crucial feature - an adjustable crossover. It would certainly add value to the system.

Perfect Upgrade For Stock System or Aftermarket Radio Only Systems

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.

Awesome Bass

bought this item for a nissan pathfinder and it cranks. I lowered the bass from my front speakers and they came alive with good mids and highs. The tube provided awesome low end power and matched perfect with the factory sound system.

Works Great!

The amplified Bazooka Bass Tube is a great addition to my car audio system. It adds deep bass and just enough punch. It was easy to install myself and has performed flawlessly for the six months I've had it.

Nice One

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.

Love it

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.
