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: 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
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.
