Got two under the seat

TWO g5's under the seat in the back of the Chevy ported and they not only hit hard but are exceptionally clear. I'm simply saying I'm happy I got them.

Hits Every Note

I have had every kicker sub...(all but the solo x) and this sub hits as good but with much more sound quality.. I have a pdx600.1 powering it and its a little more power then it needs. but it still sounds great.
And if you get the boston g5 baffle/cone thing. you will hear two subs but only power one and only need space for one sub . that's really cool

Jaw Breaker

Just received my G5 for 199.99 + free shipping. I've only been able to listen to this for a day, but so far this sub hits hard and deep!

Before installing this, I was using a 10" Rockford P3 sub, and this one by far blows that out of the water. The Rockford would bottom out on deep notes (especially on Rap), but so far the Boston has hit deep and accurately with no signs of distortion or bottoming out.

The Boston is also very efficient and I had to turn my amp down 1/4 to blend in to my other speakers.

This sub is in a small 1 cubic foot box, and it really is a nice, accurate, and deep hitting sub. Highly recommended.
