Our take on the Bazooka BTA850FH

The BTA850FH Bass Tubes package from Bazooka includes a great-sounding TA850C amplified subwoofer tube and convenient factory 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 Tubes enclosure to act like a bass cannon, firing low frequencies throughout your vehicle.

Bass Tube efficiency

BTA850FH 8" amplified Bass Tubes package

The BTA850FH Bass Tubes package from Bazooka includes a great-sounding TA850C amplified subwoofer tube and convenient factory radio connection kit. With this handy combo, you can enjoy thumping low end with a minimum amount of hassle.

Bazooka's TA850C 8" amplified Bass Tubes enclosure is an ideal solution for getting the thrill of powerful bass without making any permanent modifications, especially handy if you drive a leased vehicle. It features an efficient 8" woofer, a built-in 50-watt amplifier, and mounting hardware. Place the TA850C 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 TA850C to the factory 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 uses Posi-Tap connectors and simple, reliable plugs to get the signal from your factory radio to the Bass Tube — no splicing 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 TA850C in the rear of your vehicle.

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.

Nothing new here.... This is my second Bazooka sub. These subs are truly amazing!... It also vastly improved the sound of my existing speakers. The FAST-9999 wiring harness is a snap to hook-up and works flawlessly.

Product Research


Overview: The Bazooka Big EZ Bass Amplified Subwoofer Kit (BTA850FH) features Bazooka's patented Bass Tube enclosure design. Its a complete subwoofer solution for your truck, SUV, sedan, or hatchback. The Big EZ Bass Amplified Subwoofer Kit includes an amplified bass tube, a Fast-harness, and an extension harness.

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

8" Woofer w/ 50-Watt Amp: The Bazooka BTA850FH features an extremely efficient 8" woofer, coupled to a 50-watt amplifier for a frequency response of 39Hz to 250Hz.

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/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 BTA850FH comes with straps to keep the bass tube securely mounted, while still making removal quick and easy if you need more cargo room.

15 questions already asked

Nothing is connected to the battery with this kit ,it all plugs to the back of the head unit and everything is included in the box ,very easy to hook up. [ Michael  Apr 16, 2017 ]
It comes with everything. [ Jason  Apr 16, 2017 ]
It just draws power from your head units power line [ kyle  Apr 15, 2017 ]
This comes with a harness connector that patches into an amp that's wired to the battery. If you've got the amp, I don't think you need anything further. [ ROBERT J  Apr 15, 2017 ]
Yep, the wiring kit that comes with it is all you need. It piggy backs your radio wires for power and sound. Then you have to ground it in your trunk at the other end of the wire harness. If you have trouble with the wire colors in your car not matching up with the bazooka wire kit, just email crutchfield with your make model and year of car and they'll tell you which wires are which. [ Ross  Apr 15, 2017 ]
yep this is all u need, i actually have mine installed on golf cart [ DWIGHT A  Apr 14, 2017 ]
You should not have a problem what so ever. The unit comes with detailed instructions on how to hook the wiring into the factory system. I installed the Bazooka tube on my wife's 2010 Malibu with ease. Helpful hint: Figure out where you are going to place the tube, run your wiring first, make your splice connections with the supplied materials, then mount and plug in the tube. In the Malibu, I was able to go beside the transmission hump, under the carpet to the driver door jamb, under the door still plastic to the rear floor board, pulled the bottom of the back seat out, ran across the bottom of the seat tub, and stopped at my connection point in the trunk. You should have well enough length in wiring. Leave yourself some slack as well, just tuck it under the back seat before snapping it back into place. If you have any experience with car audio wiring is a breeze. Don't let it intimidate you. Also, as far as running the wire, take your time and be patient. Don't get too aggressive removing the trim it simply pulls off and clips right back on. I hope this helps. Hint #2: Play with the gain on the tube to get the desired sound. Your not going to wake the neighbors, but this thing will add that extra bass most all factory systems lack. I love it. [ Ron  Nov 19, 2016 ]
You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you. Hope that helps!

Absolutely! With the supplied wiring, installation is an ease if you have any car audio knowledge and read the directions. If anything is difficult, it would be routing the wires to keep them hidden. Begin routing behind your factory head unit until you reach the location you intend on mounting the tube, then begin hooking up your wiring and mounting your tube. You should have no problems. [ Ron  May 27, 2016 ]
Yes. The speaker includes an universal harness that is extremely easy to add to any factory stereo. Amp is built in so you don't have to add one. This saves space in your trunk. Good luck! [ ERNIE J  May 16, 2016 ]
it should. It literally taps directly into the power and audio lines of your current harness. [ timothy  May 03, 2016 ]

I've had a few of these units. If you use the fast connect properly , the bazooka will be protected by the head unit fuse since it connects into the head units power wire. No need to worry about dead battery in the morning. The bazookas have an automatic shut off once there is no signal being sent to it. You'll probably notice that it takes the bazooka a few seconds to kick in when you first turn the head unit on. [ steve  Jan 02, 2016 ]
I connected fine without any connection to the battery. Worked just fine and never had any issues with battery drainage. [ MARY  Jan 02, 2016 ]
You will still need to power the sub. Use only RCA cables with mine and did not work. The factory wiring kit is pretty striaght forward [ michael  Nov 04, 2015 ]
For details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle. [ Krissy  Oct 05, 2015 ]  Staff
No [ MEGAN M  Apr 01, 2015 ]
NO, I would not use this in a marine application. The woofer itself is a paper material and the electronics probably wouldn't hold up long term with the moisture. [ BRIAN  Apr 01, 2015 ]
no, this is a subwoofer for a car or truck [ TERRY  Apr 01, 2015 ]

Hello Scott, If your amp draw from the head unit and sub at rated max output do not exceed the rated amp on the fuse, you will be ok doing this. I how ever have an aftermarket head unit that controls the sub. The factory wire harness in my vehicle which already had an amp from the factory has a separate hot lead from the fuse box along with the head unit lead for powering a separate amp so I did not need to hook up a separate wire for the sub. If you do not have this style, you will need to hook up to a separate power lead from the fuse box or battery to power your sub. I hope this helps. Good luck Paul [ PAUL  Jan 29, 2014 ]
Hi Scott, I have seen online that people have wired the power both ways with good results. I was skeptical about pairing it to the head unit since it's rated max draw and fusing didn't leave much room and the wiring wasn't accessable once in place to see if it was getting too hot and might cause a problem so I opted for the safest way with a 10 amp fuse at the battery to the bazooka power supply. That way if anything ever happens to the hot lead and it shorts it will blow the fuse at the battery and not harm anything else (the old smoking wire under the dash because they were fused at that end and not the battery eventually rubbing up against something exposing the insulation and poof). So for less than $10 a rubber fuse holder and wire from my local NAPA store I feel safer with the installation and won't be looking for any surprizes. It's your call ... check what the MAX amp/volt draw is to see what you have available to insure there won't be a atrain on your fused factory link if your going to tap in on the existing supply. Hope this helps, best of luck, Dave [ DAVID J  Jan 27, 2014 ]
