So if you are looking to replace your busted factory sub or just want to add some bass to your vehicle these woofers are a great option.

Boston Acoustics has built from their previous subwoofer to bring you their new G2 series subwoofers. These subwoofer are not only an improvement but stay true to the quality and performance that comes with Boston Acoustics products.

All G2 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. G2 subs also feature a RadialVent® cooling system that decreases heat dissipation as well as distortion cause by thermal discharge.

I bought 2 of these, originally I was going to go with JL since I have just come accustomed to buy, I am so glad I bought these. Jl's hit hard but are expensive and the build at least for the comparable model were week in jl. These puppies have some of the greatest cleanest sound I have ever heard. I have them in my dodge ram with limited space and they sound better than when I had 12's in my car, one of the best subs I have owned you can also change the impedance 2-4-or 8 ohm.

This is such a quality product. The sub hits so hard and tight and very clean. I have never felt such a hit from a sub. I am pushing it with a ba gta 802. Bridged at 260 rms. It is a perfect match. For the price you will not find anything better! Thanks again Jeffrey you definatly know your stuff.

i have two of these in a small sealed box, and let me tell you this sub's sound quality is crazy. the bass is so clear and true-to-life it will blow away JL. this sub is easily comparable to the JL w3 except it sounds better and is a lot cheaper. boston acoustics have been the premier brand and fine tuning the features of these for a long time. and if you can get your hands on the G5 its even better.
