  • After seeing all of the negative reviews regarding Online Car Stereo, I was a little nervous of placing an order. But the fact that this JL Sub was impossible to find anywhere and that there was a 10% discount as well as free shipping I went ahead and ordered it. It was the genuine real deal and it sounds great. Also, it shipped and arrived in no time.

  • It's a compact sub but the sound is gigantic! Its pricey but the built-in amp has become handy as I do not have to find one to pair with the sub. Doesnt take too much space too.
