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. This improved the subwoofers ability to perform at higher power handling levels while still producing quality bass output. All G1 series subwoofer feature a co-polymer woofer cone and foam surround for rigidity and increased excursion.

Nice sub

This is a really nice sub. Sounds great without a lot of power needed. I have just one in a frontier and it added the bottom end I was looking for.

Great sub for the money

I built a custom ported box for mine. 2.07cu/ft after sub and port displacement, 4 inch wide 10inch long port makes tuning 35.2hz. My amp's birthsheet is 534watts at 4 ohms and this baby Boston has handled it no problem. It will play music all day sounding excellent and with 500 watts rms it did a 137.3dB on a a 57hz burp on the Term Lab. The mic was on the kick panel, with the door open in a Ford Contour.

This is a great sub

I've got this running on 155 watts and it sounds great. You can feel the sound.

I've got a JL 12W3 in my other vehicle and I can honestly say the both sound just as nice. I really can't give the edge to either one. For the price this speaker is a no brainer.

Granted, I'm after sound quality but I like it loud. I'm not trying to shake the block, but this can determinately vibrate your mirrors and sound clean while doing it. I'd buy another in a heart beat.

Nice sub

Very nice sub, especially for the price. Added one of these subs to an F150 and it's turned out to be a perfect compliment to my Boston components. Would definitely recommend or purchase again.
