    Great sub for the deal of the day price. It's usually on there every now and then for $30 so I decided to swap it out with my Focus ST2 sub. Running off the stock Sony amp, this makes the low's in my car tremendously better.

    As a fan of JBL portable speakers, I was hoping the quality would protect over in car audio. It did. I fell in love with the rich, booming sound this sub created. It is dangerous though as you may find yourself getting lost in the music more often.

    This is literally the go to subwoofer when it's on sale for 29.99. It's not worth the normal $140 bucks or whatever the normal price is, but everyone looking for a cheap set up this is the sub to get, especially when doing an array or something cool with multiples f them. Have it connected in my car and it sounds amazing.

    I have to admit... This is way too big for my car (corolla). It didn't originally fit in the trunk with the enclosure. But for the price I just couldn't pass it up and man is this thing something. It makes my Lexus sound flat, and I thought that was pretty good before I had this put in, and now I'm going to get another one for that.

    This sub hits hard. You Have to get it when the price is drops. It shacks my Honda crv with just 1 sub. Def will buy again. If you catch the sale it's only$29 each. Then buy 2 and feel the bang.

    I love my new jbl subwoofer. The install was smooth and the instructions were easy to understand. Now I don't know if it is just mine but when I put the sub in my car it did make it stink like I put a new set of tires in. Besides that, I still think the sub it an investment for car audio.

    My friend recommended this speaker for a subwoofer he is going to help me build. He uses these same speakers in his theater, and they sound fantastic! They often go on sale around Christmas for about $29.99
