Bazooka 8" 100W Amplified Tube Sub

I have owned this product for nearly six months, and I am quite satisfied with it. I have had no problems with quality of workmanship, parts, performance, or reliability (though, I should note that the unit turns off if the stereo is not turned up past a certain volume level, which is something I wasn't expecting for some reason). Readers should be aware that I have a low technical knowledge of electronics, and audio equipment; and while I play the bass and love music, I am not an accomplished musician or expert in sound quality either.First, I installed the unit myself. I purchased an additional kit in order to have adequate quality and length for the cables running from the back of the Bazooka unit (A/V and power) to the back of an after market Kenwood deck (and the battery, in the case of the power cable). Set up and installation were not difficult for me, though, I can see why someone not inclined to fiddle with things themselves would want to have it installed.Second, this is literally one of the only units that would fit in my 97 Nissan, single cab pickup. The seat is pulled way forward, and the unit barely fits- but it's in there.Third, I listen to all genres of music, and I feel like this unit adds the needed depth to most musical experiences. However, it should be noted that this is not a "bass system" in the sense that most people are hoping. It fills the cab of my truck with sound, I can feel it vibrating the back of my seat and see it vibrating the mirrors, but it is not the kind of gut rattling - stare inducing - wall of sound, bass for which many enthusiasts are looking. I love to listen to hip-hop, pop, and rap music. However, this unit does not necessarily do those genres justice. Is it better than door mounted speakers alone? Absolutely. Will people in the cars next to you at stop lights be able to tell what you are listening to? Nah.So, here is the bottom line. People that purchase these speakers should have reasonable expectations about what this unit will accomplish. It will add the much needed "lower end" to the music you enjoy. It is likely to keep up with the output of your deck and other speakers. It is convenient because it fits in small vehicles and does not require an amplifier. Buyers should note that this unit will be a huge disappointment if you are looking for something to carry a "bass system." It will not give you either the volume or the ultra low range of bass that is necessary to enjoy certain types of hip-hop and rap.This unit has been well worth the money I paid for it, both in its reliability and in its quality performance. Five stars.
