Summary: I drive a 2001 ford ranger. There's almost no room behind the seat. I'm only 5'9" and I enjoy having the seats almost completely back. This sub fits perfectly with a little room to spare. Also, the bass is good! It puts out tight, accurate bass that even sounds good while listening to rap and jazz. I have my amp bridged and I am pushing this thing around 280 RMS. It has been performing well so far!
Pros: Size, power handling, virtually invisible when installed
Summary: I was sceptical on buying such a small speaker for a sub and was considering the extra $$ for the 8". But, this little 6 1/2 is perfect. It sounds amazing for its size. It is very full and clear, and even hits those low notes. I got the dual 8 ohm instead of dual 4 ohm because I already had an Alpine MRP-M500 and at 4ohms it puts out 300 watts rms which is perfect for this sub since it is rated at 300 watts rms.
Summary: Absolutely Amazing. My first sub was a 8" bazooka w/ the 100watt built in. I was skeptical, but since i have a 2008 Single Cab silverado, i was very very skeptical, but was in a crunch for space.
Pros: Compact, Power Handling, Ability to buy different ohm'ed subs to work with your amplifier. Hits the low notes, and defiantely sounds like a 10.
Cons: I mean, we all know Bazooka tubes do not look the coolest, but they sure do their job
Conclusion: This fits in my 2009 chevy 2500hd reg cab and produces way more than I expected. Great product well made and loud. It is running off of the rear channels of a Lanzar MAXP4260 4 channel with a set of Lanzar MX6C's in the doors. For this application there is nothing better and I still have room behind the seats! Hits all of the notes it should and gives a good thump you can feel in your chest from the kick drum.
Conclusion: I bought this speaker and an 8" (BT8028DVC) because of limited space in my drag boat. The speakers do a great job of providing that extra "thump". But one word of caution: It is probably worth it to buy the upgraded mounts. The strap system that is provided with the speakers is constantly, and I do mean constantly, loosening up. For me that is a real headache.
Conclusion: I would recommend this product to anyone who wants a little bit of bass in their vehicle. The sub sounds exceptional it responds better than any sub i have every owned, but the other side off it is that the bass is more heard than felt. the tube makes a system sound much better but if you want to feel the bass i would go with a single ten or twelve in sub.
