About the Bazooka BTA6100

A bass cannon

The affordable BTA6100 6-1/2" amplified Bazooka Bass Tube lets you add ride-filling bass to your system with a minimum of hassle. It's an ideal solution if you drive a leased vehicle, and want the thrill of powerful bass but don't want to make any modifications. The BTA6100 Bass Tubes enclosure comes with a 6-1/2" woofer, a built-in amp (100 watts max power), and installation parts including a power/signal harness (15" power and ground wires, 10" turn on and speaker input leads, RCA inputs, and auto turn-on jumper), 7.5-amp fuse with holder, power rings, and mounting hardware.

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.

Big bass without losing space

Bass Tubes fit just about anywhere

A compact Bass Tube 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.

Important Note: You'll need to purchase an amp wiring kit to install this powered Bass Tubes enclosure — the included wiring harness is less than two feet long.

Product Research



Overview: The BTA6100 features a water-resistant poly enclosure that houses a 6-1/2" poly woofer with a foam surround. The woofer is powered by a built-in 100-watt maximum amplifier. The patented Bass Tube enclosure design eliminates bass standing waves for high accuracy, and superior efficiency.

Low-pass Filter: The BTA6100 has a fixed low-pass filter at 85 Hz with a slope of 18 dB/octave. 

Subsonic Filter: The subsonic filter, set at 35Hz, prevents really low frequencies from being amplified. This allows the amplifier to run more efficiently with increased power output.

Remote Level Control: Using an optional remote level control, you can control the bass output level of the subwoofer from a remote location.

Auto Turn-On: The subwoofer will turn on automatically when it senses music in the high-level or low-level inputs.

Balanced Input Circuitry: Balanced low-level and balanced high-level input circuitry is used for improved noise reduction.


Back Panel:

  • Level Control: rotary control that allows you to adjust the level of the subwoofer
  • Input Phase Switch: allows you to adjust the phase of the subwoofer
  • Power LED: if power, ground and remote are connected properly, the LED will illuminate in green


Back Panel:

  • Remote Level Control: minijack for use with optional remote level control
  • Harness: 14-pin Molex plug for use with supplied harness


Installation: Each mounting strap has an attached mounting base that can be secured to your vehicle using the supplied self-tapping screws. Once the mounting bases are installed, the tube is held in place by the mounting straps. For best results, the tube should be mounted facing into a corner, and there should be 2" to 4" between the woofer and the corner into which the woofer is pointing.

Required Accessories:

  • Power Wire: the 16-gauge power lead is only 10" long, so additional wire is required to extend it to the battery. Additional power wire must be crimped or soldered to the Bazooka's power lead.
  • Ground Wire: the 16-gauge ground lead is also only 10" long, and may need to be extended. Additional ground wire must be crimped or soldered to the Bazooka's ground lead.
  • Speaker Wire: required only when using the high-level inputs
  • RCA Patch Cord: required only when using the low-level inputs
  • Remote Turn-on Wire: required only if you do not use the auto turn-on feature

Customer Q&A

Crutchfield asked: Why did you buy this?
I have had a Bazooka tube in my truck 8 years w/o a problem....I bought a new car for my wife and bought a sealed type sub but it does not sound very this one is still a tube type and I can mount it to the back of 2nd row of seats.. [ 2-SWIFT  Jan 11, 2020 ]
Marketplace best. Small, removable and I've had one before [ Joseph  Dec 28, 2019 ]
Good experience with previous models of this item [ Ken  Dec 13, 2018 ]
I hope it adds the tone I am missing in my system. [ Bryan  Jul 18, 2018 ]
I owned one previously for 20 years and it rocked!! [ Joel  Apr 23, 2018 ]
I wanted a single amplified unit for my truck and this was teh best value. [ Dave  Mar 06, 2018 ]
nice and compact [ MARK  Mar 05, 2018 ]
This units compact design and easy installation has allowed me to move it from car to car over the years. Unfortunately sold it with the last vehicle. Time for a new one. [ CLINTON  Jan 08, 2018 ]
Size and space restraints [ Casey  Sep 29, 2017 ]
I chose this item because it fits in the space that I have available. I would have preferred a different sub enclosure with a larger sub but there is just nowhere good to put that in my vehicle. [ AARON  Jun 11, 2017 ]
I've owned them in the past and have proven to be a great product! [ Gilbert  Feb 07, 2017 ]
It was recommended by a specialist and I know nothing about audio. [ Cristella  Dec 15, 2016 ]
Tons of positive reviews about this, and it looked like it would fit under the rear bench seat in my 2002 F150 Supercrew, which it did. Many reviews said this sub filled out the low end of the music inside the car, without being obnoxious to the point of being heard from a block away, that's what I was looking for - good sound inside my truck without drawing a lot of attention to me. This unit delivered on that and I'm pleased with the purchase. [ michael  Aug 10, 2016 ]
I Love the Bass that this Unit produces, but it just didn't fit into my 1972 Datsun Pickup. Tried behind the bench but it caused the bench to be to far forward, if I were 5' it would be a perfect fit. I had to go with (Sound Ordnance B-8PTD) a unit that fits under the seat. [ CHARLES  Jul 27, 2016 ]
past experience [ thomas  Jul 01, 2016 ]
I have one already and they are great [ Lil Mike  May 30, 2016 ]
Always wanted good, deep bass. Already installed this item and I'm glad i did not pick the 50watt. This has enough power for what i need, it adds awesome bass to all of my music. [ YOHANNY  May 18, 2016 ]
My last 6" amplified Bazooka lasted over 16 years. (in the same truck) When I finally sold the truck and tried to reinstall the Bazooka in my new truck, the amplifier would not power back up. (actually it went out with a nasty smelling cloud of smoke) But I'd say 16 years in a truck that had constant daily vibration and temperatures ranging from -40 in the winter to +105(F) every year was a pretty good run. I have no problem buying another one. I hope it lasts just as long! [ Joshua F.  May 15, 2016 ]
I previous owned a powered Bazooka 6 1/2" sub and loved it! Recently, it stopped working. But, I must add I had it for 8 yrs! It sounded great in my Toyota Paseo which is a small two door coup. It doesn't take up very much space at all. Very few products are good quality and give great service So, I'm buying another one. [ Michael  Feb 19, 2016 ]
After reading 20+ reviews about this little bass speaker and all the reviews giving 5 stars... It made my decision easy. [ Karl  Feb 12, 2016 ]

11 questions already asked

Will this fit behind the back seat of a 02 Chevy S10 crew cab?
[ chris  Oct 07, 2019 ]
5 answers
I think it would. It fit under my 14 crew cab fine, but it is a 1500. The bass was suprising once the speaker broke in. I would go by the diameter specs and measure under the seat.
[ Mathew  Oct 14, 2019 ]
I do not know, I installed it behind the back seat of a 2005 TJ and there isn't much. The diameter should be about 7.5 "
[ Brent  Oct 07, 2019 ]
Not sure . It will fit under the back seat of a 2001 Ford F-150 supercab.
[ felipe  Oct 07, 2019 ]
It'll be tight, but I think it will.
[ Roger  Oct 07, 2019 ]
Absolutely. Follow the instructions about distance from the outer walls so you can get the best bass reflex and let it breath. Helps if the extra cab area is carpeted.
[ CLINTON  Oct 07, 2019 ]
If this fit in to the back seat of a Toyota Tacoma 2019 without modifications?
[ Djboss  Mar 09, 2019 ]
2 answers
I have a Ford F-150 and I put it on the floor in the back seat.
[ ARTHUR W  Mar 12, 2019 ]
I'm not sure. I installed this in the cargo area of my BMW X5. It is held down with 2 straps.
[ Greg  Mar 11, 2019 ]
Will this be ok in the center console of my boat?
[ Leo  Aug 06, 2018 ]
2 answers
Ok for the elements but not sound I would prefer it out of console
[ Boni  Aug 06, 2018 ]
I have had several Bazzocka's over the years. They have worked well for me. The center console of your boat we would be a great place. Use the marine version to handle the damp environment, for long lasting use.
[ Kent  Aug 06, 2018 ]
I want to add bass to my '69 Beetle convertible. Considering this behind the back seat. Reviews look good, but don't want to waste my money on bass I won't even hear back there. Not exactly a hot rod sound, but definitely a louder car than your standard late model vehicle. Would this little gem get the job done? Don't wanna rattle the asphalt, just make a little rumble.
[ Bubba42  Apr 18, 2018 ]

I am extremely happy with this Sub! While it will not win you any competitions, it will fill your bug nicely!! I put it behind my daughters bench seat in her '94 I have to turn it down as it is too much for that cab size. Truely full bass too! For fun I ran some bass test cd's through it and it was amazing for what this unit costs, and it's size! And was so simple to install and setup. Enjoy.
[ Michael  May 02, 2018 ]
Yes yes yes
[ Anthony  May 02, 2018 ]
This is a great addition if you just want to add some bass but not rattle the car next to you. I would recommend it over and over again. I have had mine for over a year now and it still kicks. Plus it's convenient - you can take it out within a matter of seconds if you need extra space and pop it back in within the same amount of time.
[ Paul  May 02, 2018 ]
This is my second Bazooka. Perfect to add a little thump. Easy to install and wire. We fully recommend.
[ Kent  May 02, 2018 ]
This is a good product. It's great adding a good solid bass for rockin' roll. Not for rapp. Easy installation. The harness that comes with it is ok. However, the one that should come with it is extra and is long enough to put in a 70s era Cadillac. Makes the job even easier. I would recommend this product for an adequate bass sound
[ ROBERT  May 02, 2018 ]
Can I have this bass tube installed without having to modify my factory system. I'm concerned because I have a newer car with a touchscreen?
[ BigDB  Apr 07, 2018 ]
4 answers
Yes you can. You would just need to splice into the factory speaker wires. This allows for both high level inputs (speaker wires) or low level inputs (RCA).
[ RYAN  Apr 09, 2018 ]
I am not sure my 98 Grand Marq does not have the factory radio. The Crutchfeild Techs should be able to help you they are great, and were very helpful helping me pick out the wright bazooka tube for my car. I think they sell some type of adapter that will allow you to hook it up to a factory system
[ charles  Apr 07, 2018 ]
Yes. You could run this off of any speaker signal.
[ stephen  Apr 07, 2018 ]
Yes. Use the speaker level inputs in the bass tube and tap some wires off of your vehicle L & R speakers near the Bazooka, then choose the auto on function that senses a sound signal that turns on the bass tube. This way you do not have to interface with the factory head unit at all. The Bazooka will get its sound from the taps into the factory speaker wiring and will auto turn on when it senses a loud enough sound signal from those speaker taps.
[ Al  Apr 07, 2018 ]
Can this sub be installed on its side. Meaning cannot be installed with the tube turned so the it is 7 inches high and 9 inches wide?
[ Dominic  Aug 19, 2017 ]
3 answers
[ MIKE  Aug 23, 2017 ]
Yes Dominic, the position of the tube makes no difference in the operation. As long as the open end is not blocked it should be fine.
[ WILLIAM  Aug 19, 2017 ]
all of the wired connections run into the flat bottom of it so you couldn't stand it up on it's end without affecting those.
[ Robert  Aug 19, 2017 ]
Will this fit behind the seat of a 1996 Chevy S10, regular cab?
[ Marvel  Jun 08, 2017 ]
2 answers
Yes it will. It's not big and bulky and will creat great bass
[ KENNETH E  Jun 09, 2017 ]
it depends on how far back the seat is slid.
[ Robert  Jun 09, 2017 ]
Would you recommend the 6.5 powered bazooka tube in a 2006 prius? Once the laughter subsides, I'd appreciate some guidance on whether it's worth the effort or not. Thanks.
[ Hitman  Mar 29, 2016 ]
2 answers
NO worries on laughing. I bought one for a golf cart and so didn't need to be bumping down the road to save on gas but it did really great filling the low end of other 4 speakers. I had the 4 speakers hooked up to a 4 ch. Kenwood app that easily tucks in small places (golf cart radio console had perfect spot for it and then the powered bazooka tube and it sounds awesome for being a small sub. So if ur wanting to save space then the bazooka tube is great but do research on other powered subs that can fit under seats and may be beneficial and check reviews and ask more questions but the bazooka tube does sound nice for its size
[ David  Apr 06, 2016 ]
I have one that I put in my 3rd Gen MR2. Doesn't really thump very well at all. Not really happy with it.
[ Gene  Mar 29, 2016 ]
How would 2 of these work with a pioneer amp 1000 watt in a f150 xlt 4 door with a syn factor system?

REVISION: Sorry Isaac, but I"m not a technical person. I had bought the Bazooka BTA6100 for my Honda Goldwing motorcycle and had a tech at the dealership do the wiriing. Once again, sorry I was unable to answer your question.
[ MICHAEL  Oct 29, 2014 ]
Sorry Isaac, but I, not a technical person. The Bazooka BTA6100 I bought was my 2004 Honda Goldwing motorcycle. I had a tech at the dealership do the wiring. Once again sorry I could not answer your question.
[ MICHAEL  Oct 29, 2014 ]
I bought one for my Toyota truck and it works better than any base speaker I have ever owned. It comes with straps attached to base plates that can be screwed into a wood base or whatever. Two of these would be AWESOME. I would definitely buy two of these the next time I build a great truck stereo, Randy H DSD
