About the Bazooka BTA8100FHC

A bass cannon

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.

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.

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.

Do you know anywhere i can purchase just the wiring kit? I have the tube itself, but lost the wiring about a year ago.

Sorry it took me a while to respond. I have in the past ordered a harness directly from SAS Bazooka. It's a little tricky. I went to their website and looked at the owners manuals. From there I was able to figure out which unit I had and then I ordered from it directly from SAS. Hope this helps.
[ CHRIS J  Sep 30, 2018 ]
I'm almost certain you can purchase one here on Crutchfield. If you look on the page that has the model you have, scroll towards the bottom and you should see replacement wiring kits. Hope this helps.
[ Gregory  Sep 27, 2018 ]
will i have to ground a wire with this?
[ Christiano  Aug 10, 2018 ]

It has a ground wire .Screw it to metal in ur trunk.
[ adam  Aug 10, 2018 ]
[ KENNETH  Aug 10, 2018 ]
Yes, you will have good source to ground too.
[ Scott  Aug 10, 2018 ]
Can this tap onto the rear speaker wires of my factory system, providing crossover to send higher frequencies to the rears while amplifying the bass??? (without having to tear apart the interior to install?)
[ r  Aug 15, 2015 ]

It can, as I did. Plus this allows me to - if needed - shut the sub off while driving simply by fading to the front speakers.
[ Mike  Aug 16, 2015 ]
Yes this is all accomplish with the provided harness
[ JAY  Aug 16, 2015 ]
I don't think so. This is a powered sub and easiest to use the harness to your factory system. Also recommend the bass control module for equalization by music genre
[ Michael  Aug 15, 2015 ]
Does this item require you to run power from the battery? Do you have to go through the car's firewall?
[ R  May 14, 2015 ]
7 answers
yes it does, if you can't find a place in the firewall look under the vehicle sometimes there is a plug or somewhere easily available you can route the wire through
[ JAMES  May 17, 2015 ]
I Didn't connect it to the battery. I ordered an extra wire harness but I don't think I used it. I used wiretaps to the rear speakers on the back of the back of the head unit and with the remote volume control it works great.
[ matt  May 15, 2015 ]
No,i bough this item and it instructs that you simply wire it to your headunit. Its not too powerful--barely powerful enough
[ ROBERT J  May 15, 2015 ]
Get the one with the harness it connects to your car stereo
[ Michael  May 15, 2015 ]
You do not need to run power from the battery for this sub. I believe you do for the 10" version however. If you do need to get power from the battery you can run it through the firewall, there are grommets around where your feet rest on the pedals that you can usually run line through.
[ Reed  May 14, 2015 ]
NO it powers up through the stereo adapter kit that comes with the bazooka, but the adapter on the back of the tube has a ground wire that has to be grounded really good to power up.
[ SAMUEL  May 14, 2015 ]
No, you just have to fast connect it to the power wire that runs to the back of your vehicle radio.
[ SEAN  May 14, 2015 ]
Will this work on 2005 GMC Yukon Denali with the Bose Primium system? (5 channel)

[ Michael  Mar 10, 2015 ]
Yes if your head unit has Rca outputs Or you can use the supplied Bazooka wire harness that has wire taps on the positive and negitive speaker wires if you want to tap into your systems speaker wires.
