    • Mediocre sub

      I bought this sub on a whim because of the price and I wanted to save some trunk space in my car, but the sub doesn't really put out much bass and can't handle the power the manufacturer claims it can. I only pushed 175 watts to this sub and its a 350 peak, 150 rms sub and I blew it in a matter of days. If you are looking for some bass, I'd buy 3 or 4 of them and start from there.

      This product was way beyond what I was expecting, as far as quality. The price was a huge surprise. I ordered product from a popular business, and it cost over ten times the amount I paid for this one subwoofer, and I found out that if I had kept the merchandise I originally ordered, I still would have had to buy an enclosure for the subwoofer. When I found this subwoofer, and found that it was all I really needed, I was able to send all that previously ordered merchandise back, and saved myself a HUGE amount of money.
