The single 4 ohm voice coil allows you to run the sub at a very efficient 4 ohm rating on just about any amplifier. Or it allows you to add an additional subwoofer for more bass and a variety of wiring configurations to better suit your needs and budget.

Boston Acoustics is well known for their amazing quality and products in the home audio world. Their dedication to quality and performance is seen in all of their products, including the G1 series subwoofers.

All G1 series subwoofers are equipped with Boston Acoustics specific technologies such as SureSet™ impedance selection that makes wiring easy and accurate as well as adds protection from overdrive to the voice-coil. G1 subs also feature a RadialVent® cooling system that decreases heat dissipation as well as distortion cause by thermal discharge.

I mounted a single 8" in the arm rest area between the rear seats of my 2003 Chrysler 300M. Would have not believed it was possible to get that kind of performance out of such a small speaker. Putting about 400 watts to it. Been using it for 6 months. Getting ready to a new set up in the rear deck of my mustang using the same speakers.

I bought this here. It has great deep bass for an 8 inch". Mind you its not earth shattering, it is clean and plays all low frequencies very well. I would recomend it for those who want a clean sound quality vehicle without the over pronounced boomy bass most subs have.

I purchased a pair of these for a custom down firing subwoofer in my van. They seem well made and sound great. Plenty of bass for my needs - I usually listen at moderate volumes. I would buy them again.

It sounds ok for what it is, it doesn't hit the really low notes like a 10" or 12" subwoofer but is very musical. One of the wires came loose after about a month and I had to solder it back on, other than that it has worked great.
