This was my first setup I've had in my car, and they shook my mirrors. It was weird, 'cause I couldn't hear them outside of my car unless I had my head in the window. Wish they could've put 'em in a bigger box though.

The purchase of my Sonic subwoofer kit was very good experience from start to finish. I'm very happy with the speakers and the kit had all the necessary parts to install the sub-woofer. The only thing that I would have liked in addition would be a grill to protect the speakers.

So far so good but i was expecting them to be louder based on other peoples reveiws, mine are in a trunk however and that dampens them alot. They definitely add a good amount of bass to the music and definitely not to the point of it being overpowering. The wiring kit is garbage though and i recomend you buy new wiring for it. Overall, id say you get the amount of bass you pay for. id like to be able to turn my subs up to the point where you drown everything out just for fun, but you wont be able to do that, not in my car anyway (2000 3 series bmw)

sounds ok for the cost its not mindblowing bass but got good thump to them thats all i need for me

Great product, Nice sound easy to install

This set up was fairly easy to install but comes with NO speaker wire! Make sure you have some! I would only recommend this kit to someone who doesn't plan on bumping it too hard. That's what I thought I was but I got addicted and I'm looking to really bump up my system. The left casing on the actual sub came loose and I don't know what to do about it because it's on the actual speaker and I don't want to mess it up. Good first kit, don't plan on having it for more than two years I would say. You will want more. And more.
