Well, I got half of my day's project done. Ordered two Bazooka tubes from the same place at the same time, and only one showed up. The second one never shipped. Called Amazon, not only will the second one be here tomorrow (free overnight shipping), but they extended my Prime renewal a month. I really can't complain I guess.
Wired in series for an 8 ohm load currently, so 300 watts running to it. Once under the floor and all of the carpeting reinstalled, it sounds damn good. Hits harder, extends deeper, can feel it through the car more since it's physically in contact with the metal floor of the car (makes it seem bigger and stronger), and once tweaked a little, blends better with the front stage.
