Our take on the Bazooka BT8014

The BT8014 Bass Tube features a 8" polypropylene woofer with a twin-layer compressed foam surround for smooth excursion. The 4-layer voice coil ensures reliable power handling for plenty of punch, and its 4-ohm impedance allows you to power multiple tubes with a single amp. The tube design eliminates standing bass waves for accurate response and high efficiency. Find a good spot for a Bazooka Bass Tube in your vehicle and you'll still enjoy plenty of cargo room.

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 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.

one of the best value on the market, very nice sound down to 65 hz, with a 80 watt amp, the sound is also powerful.



Perfect sound balance with my application

Gipper from Tennessee on 5/10/2015

Crutchfield Customer Review (What's this?)

If you want to upgrade your factory sound system but not kill your wallet this is a great product to compliment your system upgrade. Music is best in balance. My application is a 1995 GMC Sierra SLE Ext. cab. Factory system in this model? Let's just say almost anything will put out better sound. Ok I put in a decent Pioneer deck 50 watts per channel. Next the door speakers were replaced with Infinity Primus 2-way component speakers(70 watts RMS). I also replaced the factory component tweeters that sit above the 6 in door speakers but installed them as the factory ones were.(I do like the "hidden/original factory" look) Next was the subwoofer upgrade and for this model truck and many others just like it the 8" Bazooka tube fits perfectly underneath the rear bench seat(driver side) without having to modify anything! The sub is does not take any "used" foot space and it leaves approx. 6" between speaker face and LH pillar(Bazooka tube needs to face LH pillar in this application) Alright now for the power supply. I am using the Lightning audio 4100 Mini. I did my homework with power, space, and quality for my specific truck and this amp is perfect. It fits perfectly underneath the driver seat.(I took my seat out and lifted my carpet for easier install and wire routing). 2 channels push the doors and the other two channels are bridged to push the Sub(150 watts rms) Deck is just pushing the rear pillars. It sounds great. Cost? approx. $400 upgrade(DIY)

Pros: Size,Versatility and perfectly balance bass to compliment the rest of the music spectrum. When you look in my truck it's hard to see that I have a upgraded system....out of sight and mind. What I mentioned above with my install will not win any "bass competitions" but I promise you won't be disappointed with a Bazooka tube. It's like this....your somehow shooting a 45 caliber bullet out of a 22 caliber gun.

Cons: None to speak of

Great product

TMS from Belleville, IL on 10/1/2010

Crutchfield Customer Review (What's this?)

I needed something to fill in the bass that my Polk Audio components simply weren't going to be able to do. I'm sending this 150 watts off a bridged 4 channel amp and am pleased with the sound. I wasn't looking for a huge 'thump', but something to cover the lower frequencies (at a reasonable price). It's doing what I asked it too. The mounting straps are pretty cheesy and cheap, but for the price, I guess that's what you get.



Bullet proof

wjs1820 from Western CT on 1/6/2010

I have had owned and abused the same bazooka subwoofer in my vehicles since 1990. It has been knocked around and survived 20 new england winters and summers (knock on wood). I've run this thing over and under powered in 4 different systems and it's still thumping.I like my system musically balanced and this sub adds low end presence that you can feel without blowing out the windows. I primarily listen to different variations of rock music and it sounds great to me with 50 watts and plus 3 on the bass tone control. I'm using it in my Silverado pickup truck tucked nicely under the back seat and one 10" driver is enough to fill. In the past 6 years I've had to replace my amp, door speakers and head unit each after a respectable level of service but this sub is by far the most reliable piece of equipment I've owned.My current system is an Alpine head unit, (w/ sirius & Ipod controls) Sony 5 channel amp, Polk 6 1/2" seperates in front, polk 4x6 rear and the Bazooka 10" all from Crutchfield.



Big Bass On Small Budget

jtran76 from Dover, PA on 7/31/2009

I was very surprised on how much bass this 8" bass tube produces. I previously had a 10" Rockford Fosgate Prime in a sealed enclosure pushing a 100 watts rms using old school 2 channel amplifier in a 04 Mazda3 hatchback. This 8" sub out pounds my 10" Rockford sub. When people listen to my car stereo nobody believes that I am using a single 8" sub until I show them. Everyone that listen to my car stereo said it sounds more like a pair of 10" subs or a single 12" sub. Definitely worth the money. Like a lot of people I was very skeptical at first about bass tubes. Now I would definitely recommend this to anyone that is on a budget and don't want to break the bank with having to have a huge amp or taking up a lot of trunk space just to have big bass.



good sound, awkward to mount

Mr. Tibs from Chicago, IL on 4/20/2008

In the trunk of my 2000 Lincoln Town, 500-watt RMS Kenwood mono sub amp. Is there enough bass?.... yes... but is there more than enough bass?... no (you know what I'm talking about). I was surprised that at only 8" it does a very good job of penetrating through the back seat into the passenger compartment and rounding out the music, but does it produce the super deep bass of my previous sealed Infinity 12" with 1800w peak power handling... no. Also, the enclosure's shape lends to good sound, but makes it awkward to mount. The bulk of the weight is at the driver's end, so a single metal strap mount (like I've done) should be placed closer to that end, where the center of mass is, for optimal security. All in all, great boom for the buck.



Perfect for my truck

dj12563 from Colorado on 4/8/2008

Crutchfield Customer Review (What's this?)

I installed this in the rear area of my S-10 extended cab and it is perfect for what I wanted. As stated before, this won't blow out your neighbors windows or set off car alarms, but it does provide plenty of low end to your system. I am running this Bazooka bridged off a Profile amp. I am very pleased with it so far. The only thing I don't like is the cheap bracket and strap mounting setup, but it is functional and wasn't a big enough deal for me to rate it lower.



Clear, solid bass

mark from San Diego, CA on 7/23/2007

Crutchfield Customer Review (What's this?)

I bought a 6" tube for my son's truck and was amazed at the amont of bass coming from that little sub, so I bought an 8" bazooka for the trunk of my Suzuki Esteem. First off, this sub is very efficient, it will achieve fairly high bass levels with a lower powered amp. The bass is also very clean and not at all distorted, it will compliment your existing speakers rather than overpower them. The space saving design is also great if you have a small trunk like me.



great sound and bass

cole from charlottesville, va on 1/2/2006

I have a 91 ford ranger, and i knew normal component subs were not an option due to space. i got two 8inch bazookas and couldn't be happier with the bass considering the price and convenience.



Quality Sound

Rodney from Columbia, SC on 4/5/2005

Crutchfield Customer Review (What's this?)

I just installed one of these in my 1992 Nissan 300ZX along with a Alpine MRP-T220 amp and the bass is incredible. I had my doubts at first, but the quality of the sound is well worth the money. All of my friends could not believe that one 8in subwoofer could produce that much bass. Anyone would think that it was two 10in subwoofer easy. I'm very pleased with my purchase




Hands-on research

Product Research


Overview: The BT8014 features a water-resistant poly enclosure that houses an 8" poly woofer with a foam surround. The patented Bass Tube enclosure design eliminates bass standing waves for high accuracy, and superior efficiency.

5-Way Binding Posts: The 5-way binding posts will accept bare wire, pin connectors, spade lugs, banana plugs, and dual banana plugs.

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.
