I saw a Bazooka TA850C on e-bay for $15. I asked my friends about it, and they all said it's 8 inch woofer was too small, 50W amp was too low, and Bazooka tubes sound like shit.
When I got home, I thought, for $15, how can I go wrong anyways, I bid on the Bazooka, and won it for $17.
I installed it last night, and for $17 plus $10 for an amp wiring kit, all I got to say is
The bass was clear, loud and set at maximum, will gladly overpower the music your listening too with headache inducing vibrations. For a basic sound quality setup, 8 inches and 50 watts is more than sufficient. Even at the highest bearable volumes there was not even a hint of distortion- the same cannot be said for my otherwise stock speakers. For me, the tube was supposed to suppliment the stock speakers, and correctly tuned, the tube does just that- filling in subtly where the stock speakers let off.
An added bonus is it's very compact size and light weight (<25lbs)- another very important consideration I had before purchasing the tube. One inherient problem with the design of the tube is that it's round, and it will roll around if not secured. You will have to drill holes into your trunk floor to secure the supplied tie down straps- or come up with your own ingenious way to do it.
Installation was easy, the hardest parts was just trying to figure out how to take apart certain parts of the dash to get to the firewall and headunit. I was also lucky my car already had a firewall access point specifically for wires. The supplied instructions were straightforward and easy to follow.
Either way, if your looking for loud in your face bass that will vibrate your internal organs loose, destroy your car and the cars in the immediate vicinity, this tube is not for you. If your looking for a simple setup, small, lightweight and cheap to suppliment your OEM system, you cannot go wrong with a bass tube.
