A bass cannon

Bass makes up about 30% of your music, and it gives music its power and impact. A good subwoofer can make an average car audio system sound good, and a good car audio system sound great. Good bass is all about moving air, and a cylindrical tube translates the motion of its woofer into maximum air pressure so you hear and feel more bass. Bazooka designed the Bass Tube to act like a bass cannon, firing low frequencies throughout your vehicle.

Bass Tube efficiency

BTA8100FHC 8" amplified Bass Tubes package

The BTA8100FHC Bass Tube package from Bazooka includes a great-sounding amplified subwoofer tube and convenient radio connection kit. With this handy combo, you can enjoy thumping low end with a minimum amount of hassle.

Bazooka's BT Series BTA8100 8" amplified Bass Tube gives you the thrill of powerful bass without having to make any permanent modifications, especially handy if you drive a leased vehicle. It features an efficient 8" woofer, a built-in 100-watt amplifier, and mounting hardware. Place the BTA8100 in a convenient spot in your vehicle, connect it to your car stereo, and enjoy some punchy bass while you drive.

Fits in almost any vehicle

The included F.A.S.T. combination from Bazooka features everything you need to hook up the BTA8100 to the factory or aftermarket radio in your vehicle: the F.A.S.T.-9999 universal harness and a 16-foot extension cable. The F.A.S.T.-9999 universal harness taps into your radio using Posi-Tap connectors and uses simple, reliable plugs to get the signal from your radio to the Bass Tube — no splicing or complicated wiring diagrams needed. Hook the other end of the universal harness up to the 16-foot long F.A.S.T.-BTAH extension cable, which you've connected to the BTA8100 in the rear of your vehicle.

Big bass without losing space

Bass Tubes enclosures fit just about anywhere

A compact Bass Tubes enclosure will fit in almost any vehicle, and you can disconnect it in a snap if you need more cargo space. Since the tube's speaker and port are right next to each other, you can get amazing results by "corner loading" your tube — placing it in a corner of your trunk or cargo area so your vehicle's boundaries act as a natural amplifier, boosting bass production.

Bass control from the driver's seat

An optional wired Remote Bass Control Module gives you independent in-dash volume control of your bottom end. Want to know more? Take Bazooka's Bass Tubes Tour.

Who needs a powered subwoofer?

To produce bass, you need a sub, an enclosure, and an amplifier, and it can be little tricky to match them all up. A powered sub eliminates all the hassle, as the manufacturer designs the enclosure to house the sub and amp together. This all-in-one solution is especially useful in smaller vehicles, where there's no room to mount a separate amp, or in any vehicle where you need every bit of cargo space. Powered subs range from small, flat boxes that fit under your seat to larger boxes that go in your trunk.

Just what I needed

Written By TKO, Indiana on Tuesday, September 08, 2015

Crutchfield Customer Review (What's this?)

Installed this in a VW Tiguan. Bought the car thinking there would be a factory option. Much to my surprise there wasn't. I needed something that would add low end yet be quick to remove when I need extra space. The Bazooka Tube is perfect.

Pros: Enough low end to add some life to my music. Every vehicle needs one.

Cons: No complaints.

Killer product!!! Excellent price, VERY fast shipping, and simple install directions. Self-installed in under an hour and I am extremely pleased with the amount of bass this Bazooka pumps out. Highly recommended.

Pros: Easy install, fast shipping, great subwoofer.

Cons: None

A great boost in quality

Crutchfield Customer Review (What's this?)

Does a great job of enhancing the stock radio in a 2010 CIVIC LX.

Pros: Ease of installation. Overall sound


Written By CHRIS M, Florida on Friday, November 14, 2014

I LOVE THIS PRODUCT! I ordered this bass tube on a Friday and had in my hands on Wednesday! Fast FREE Shipping! It was professionally installed at an audio store that has done all the work, including window tint, on my car. They had the bass tube installed within an hour for $53. Provides enough bass in my 2009 Civic Coupe without rattling the entire car. Nice amount of "Boom". No regrets here!

Pros: If you are looking for enough bass for "you" to enjoy and not the entire neighborhood - GET THIS PRODUCT! Easy install, small so I have truck space, great "BOOM" for the Buck!

Cons: Only one con for me - I wish that this came with the wired remote so you could control the level of bass from inside the car - but it is only a $20 upgrade. Will be having the remote installed at some point - in the meantime its not hard to open the trunk and adjust to your desired level.

Crutchfield Customer Review (What's this?)

Very easy to install and rounds out the sound nicely. Not going to rattle the windows with this but it fits so nice under the back seat of my 05 Silverado. I took a star off for the" Fast connector system". Very easy to strip the little twisty things

Pros: Well made Good sound

Crutchfield Customer Review (What's this?)

I am very impressed with the sound quality of this sub. I have a stock Ford Focus and I was able to connect it directly to my stereo. I highly recommend this product if you want to a more thump to your car without breaking your wallet. Crutchfield support was awesome and assisted me when I had a couple questions.

Pros: Sound,thump, ease of install and compact design

Cons: none

great product

Crutchfield Customer Review (What's this?)

installed sub in my daughters 2002 celica gt to factory head unit. sounds great !!!! wiring was a breeze with the quick connect harness. only took about 1 and 1/2 hours from start to finish. at least 15-20 minutes was spent looking up color codes for front speaker wires and figuring out where I was going to run the harness. also installed optional remote, for $20.00 its a must have and works great.

Pros: sounds great, easy install. do not have to run power line from battery with this model

Cons: none at all

Great Product

Crutchfield Customer Review (What's this?)

The sub provides plenty of bass to give a full sound. The RBCM-100, wired remote, makes a nice addition and allows the bass to be controlled easily. I have mixed feelings on the "F.A.S.T" wire connection but it does the job. Definitely a good buy and would purchase a similar unit in the future.

Cons: None

Nice tight Bass

Written By DAN, Pittsburgh, Pa on Monday, July 12, 2010

This sub does its job. Its not ground shaking bass, but plenty of bumpin bass.

Excellent Product

Written By Anonymous, South Florida on Thursday, May 27, 2010

This product is AWESOME. I can't believe how well it sounds in my hatchback. I dropped 4 Infinity speakers into the stock locations and paired them with this unit. I left the aftermarket stereo. At first I was a little skeptical because I thought I needed the 250W version. But this tube is more than enough to give you a heck of a bass punch and my car actually shakes. The sound is clear, clear, clear.

I only refrained from giving it the 5 stars because my installer had a problem with the installation; turns out that the clips on the F.A.S.T. system that connect to the speaker wires are very poor and he had to use alternate clips. And Bazooka's customer support is poor.

I would definitely recommend this product. Don't just read this review; check out the reviews left on the other 100W Bazooka's (without the FAST harness) because they are 100% accurate!

Product Research


Overview: The Bazooka Bass Amplified Subwoofer Kit (BTA8100FHC) features Bazooka's patented Bass Tube enclosure design. It is a complete subwoofer solution for your truck, SUV, sedan, or hatchback. The kit includes an amplified bass tube, a Fast-harness, and an extension harness.

Bass Tube Type Enclosure: The Bazooka subwoofer's patented Bass Tubes bass-reflex enclosure design allows for use of 100% of the woofer's cone area.

8" Woofer w/ 100-Watt Amp: The Bazooka BTA8100FHC features an extremely efficient 8" woofer, coupled to a 100-watt amplifier for a frequency response of 39Hz to 85Hz.

Corner Loading: The Bazooka Bass Tubes enclosure is optimized for corner loading. The Bass Tube enclosure's port and woofer are on the same plane and in close proximity for maximum corner-loading results. The corner of your car amplifies the concentrated bass output of the Bass Tube enclosure.

F.A.S.T. Harness: F.A.S.T. is an innovative universal harness system that allows you to integrate the Bazooka subwoofer into the vast majority of factory and aftermarket sound systems. The included FAST-9999 universal harness uses the patented Posi-Tap connector from Posi-Products for making fast, secure connections to your OEM or aftermarket headunit's wire harness. The included FAST-BTAH extension harness is routed from the Bazooka Tube location to the radio; one end connects to the FAST-9999 universal harness, and the other end to the amplified bass tube. The extension harness also contains RCA line level inputs (at the radio end) and a ground wire which will need to be grounded to the metal chassis of your vehicle.

Note: The FAST-9999 universal harness features the following wire leads - Red (+12V), Blue/White (Remote turn-on), White (LF+), White/Black (LF-), Gray (RF+), and Gray/Black (RF-).

Signal Inputs: The included FAST-BTAH extension harness has line level (male RCA plugs) and speaker level (Posi-Tap connectors on the FAST-9999 harnes) inputs.

Mounting Straps: The BTA8100FHC comes with straps to keep the bass tube securely mounted, while still making removal quick and easy if you need more cargo room.
