Bazooka Bass Tube Technology

The BTA6250D Bass Tube features a 6-1/2" woofer and a built-in Class D 250-watt amp that delivers strong bass without taking up extra space. A variable low-pass filter allows you to tune the bass output to match up with your vehicle's sound system. You'll also get an installation kit that includes a power/signal harness, 20-amp fuse with holder, straps, and mounting hardware.

Want to double your bass? With an optional speaker-level output adapter, you can connect a second passive Bazooka Bass Tube to the built-in amp for a serious boost in bass response. An optional wired Remote Bass Control Module gives you independent in-dash volume control of your bottom end.

Important Note: You'll need to purchase an amp wiring kit to install this powered tube.

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.

Product Research



Overview: The BTA6250D 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 120-watt digital amplifier. The patented Bass Tube enclosure design eliminates bass standing waves for high accuracy, and superior efficiency.

Low-pass Filter: The BTA6250D has a low-pass filter that can be adjusted from 60 to 250 Hz.

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


Level Control: There is a rotary control on the rear-panel that allows you to adjust the level of the subwoofer.

Crossover Control: The unit's rotary control is found on the rear-panel and allows you to adjust the low-pass filter from 60 to 250 Hz.

Power LED: If power, ground and remote are connected properly, the LED on back of the unit will illuminate in green.


Remote Control: Phone-type jack for use with an optional remote control; found on rear-panel.

Power Harness: Two quick-slides for use with supplied power harness; found on rear-panel.

Signal Harness: 14-pin Molex plug for use with supplied signal 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 12-gauge power lead is only 11" 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 12-gauge ground lead is also only 23" 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 to connect the remote turn-on lead to the amplifier turn-on lead of your radio

Good, No-Nonsense Add-on

Written By Peter, Meriden CT on Tuesday, March 15, 2011

Crutchfield Customer Review (What's this?)

The BTA 6250D replaced a 15 year old 6.5" powered Bazooka whose amplifier
had died. I contacted SAS directly to see if the amp could be repaired or
replaced. While it could not, the customer service I received from SAS through e-
mails was exceptional. That was enough to convince me to go out and buy
another SAS Bazooka.

I like the "all in one" concept of the Bazooka. I highly recommend a model with
an adjustable crossover, to fine tune the sound. This unit does all it claims
without taking up a lot of space or being difficult to install.

I also ordered the remote control. It's extremely worth it if you like to fiddle with
your settings as the music changes. The only caveat is there are no instructions
with the remote. While installation is a breeze, there's nothing to tell you the
controls on the amp influence the range of adjustment available on the remote,
so it's probably best to max out both knobs on the Bazooka and do all your
tuning on the remote control.

Crutchfield Customer Review (What's this?)

This is a very compact sub which fit's in tight spots. I have a small pickup with no extra
cab so space was an issue. Unfortunatly I am a bass freak so I will also purchase the
slave tub for double the boom!

Buy one.

Crutchfield Customer Review (What's this?)

I put this unit in my 02 Forester. This sub definitely has HUGE hit for the
size/money/wattage. Bass drum is a solid kick to the back with some headroom to
spare. Installation was easy and straight forward. I can just pull the
straps, unplug the 2 connectors, put them in a compartment I had in the floor
and this thing is completely out of the way to put whatever in the back.

My one complaint is that sound quality is good but boomy. I'm used to my car
which has two 6.5" in sealed boxes so it may be that this is typical for a
ported tube like this. I think that if it was in a trunk or my door speakers
were amped instead of deck driven the boomy sounds would go away.

Conclusion: Definitely recommended and I give it 5 stars despite my one complaint.

Great product

Bought the BTA5250D along with the BT6014. Fits great in my 2007
Chevrolet Silverado extended cab.

Amazing sound from two 6-1/2 inch subs. I would highly recommend these
to anyone wanting to add fuller sound to their car. You'll be amazed at the
amount of bass produced by these subs. They've been great for all types of
music... They hit hard with rock and produce good lows with hip hop/techno.

Small size / BIG SOUND

Written By GARY, Chapmanville, WV on Monday, February 16, 2009

Crutchfield Customer Review (What's this?)

We replaced the entire factory stereo system in my wifes 95 Camaro. We installed a Sony Xplod head unit with 52 watts per channel & 4 Sony 200 watt speakers in the stock locations. Now this was a huge improvement over the 14 yr old factory system.....but I wanted to add some kick. Well, my wife was worried about I found the powered Bazooka....very small & clean looking........WOW.....what a difference.....lots of bass & very clean sound all the way around. Who would have thought that such a small package would have such a big kick. I think I want one for my truck now....should fit behind the seat & what a great sound. AAA+ OH...all we had to get for this was an amp install kit & we were set!!
