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.

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.

Why did you choose this?
Sonic Electronix Store
i've had several Bazooka's over the years. i have a 10" in my car now and it sounds pretty good. Adding this to another vehicle that has deck power and 4 speakers because it is simple, easy to remove if you need storage, and haven't found anything yet that offers so much bass (when properly placed) for the size and money.

It will fit behind the seat of my 1974 dodge w100

Owned one before and it was great. Took advice from Crutchfield and they sold me a piece of junk Sound Ordnance sub and told me it was better than the Bazooka. Its going back and I am going with what I know works

Was very happy with 6 1/2" passive Bazooka Sub and 8" passive sub, and need a replacement to my Clarion under-the-seat SRV314 powered sub. Head unit is 4 x 50 watts, so it seemed like the logical choice.

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.
