Our take on the Bazooka F.A.S.T.-9999

Bazooka's Factory Audio System T-harness (F.A.S.T.) system provides a quick, reliable, and great-sounding connection between your car stereo and your amplified Bazooka tube.

Bazooka's Factory Audio System T-harness (F.A.S.T.) system provides a quick, reliable, and great-sounding connection between your car stereo and your amplified Bazooka tube.

The F.A.S.T.-9999 universal connection harness works in conjunction with the BazookaF.A.S.T.-BTAH extension cable, and gives you an easy way to integrate a Bazooka 100-watt Bass Tube into your factory or aftermarket sound system. The wires taps are color-coded for easy identification — just insert the wire to be tapped into the Posi-Tap cap and hand-tighten into the barrel (the conductor point pierces the tapped wire — no crimping or cutting required). Run ground wire, mount the powered Bass Tube, connect the F.A.S.T.-BTAH cable to the tube, and enjoy some responsive bass. The F.A.S.T. system does not work with 200-watt Bass Tubes. Warranty: 30 days.

Crutchfield Customer Review (What's this?)

This harness does make installation a bit easier .My only complaint is that the screw terminals which are plastic are kind of flimsy. The plastic screw caps crack VERY easily when tightening them down.Metal would be a lot nicer.

Pros: Quickens connection to head unit.

Cons: Plastic screw terminals break easily.

The wire harness was easy to use and esay to understand even though i didn't Have the right harness for the bta 10100

Pros: Like the fact it had quick connections and was easy to use.

Cons: I thought i had ordered the harness that connected to the back of the bta 10100 it self but i guess you guys dont carry it so i used the breakdown of the unit its self and extended the wires and used the the Bazooka F.A.S.T.-9999 to power. Still made use of it

Hands-on research

Product Research


Application: The Bazooka FAST-9999 universal harness allows quick and easy installation of your amplified Bazooka tube with your factory or aftermarket radio when used with the optional FAST-BTAH extension cable (item number 204FASTBTA, sold separately).

Compatibility: The FAST-9999 harness/BTAH extension combination is compatible with most factory and aftermarket head units and with most 100 watt and 50 watt amplified Bazooka Tubes, including (but not limited to):

  • BTA6100, BTA8100, BTA10100
  • MBTA8100, MBTA10100
  • BTA850FH, BTA8100FHC, BTA10100FHC (included with these models)

Connection: The FAST-9999 universal harness has a 6-pin Molex plug on one side that connects to the FAST-BTAH extension cable (sold separately, see above). On the other side are 6 Posi-Tap connectors that hardwire to your radio's harness (the six wires include left and right speaker-level audio positive and negative, switched power, and turn-on trigger). Posi-Tap connectors allow you to tap into wires without cutting or stripping them. Each connector has a tapered design and a threaded cap on each end. Just insert the wire to be tapped into the cap and hand tighten into the barrel. The conductor point pierces the tapped wire without compromising its conductive integrity.
