It's a good starter sub. My bro had 2 of them in his car with custom boxes and they hit very hard. He only had about 110 RMS going to each and they slammed good and hard. The highs and mids were excellent, but the lows weren't as good as they could have been. Maybe that was due to the sealed box they were in. But overall, they were good subs. Simplicity can be some of the best stuff. Get 2 of these and you won't be disappointed.
