great

For the price it can't be beat. Impressive crisp bass and yet so small. I got two 8 inch in a box and only got a 400 watt amp pushing them and the definitely make some noise. Would recommend for small car truck SUV because does not take too much space and sounds good. 5 star for being an 8" Subwoofer. One thing I had happen is the center cone fell off, I think the direct sun light heat, had something to do with it as well. Good supper glue, good as new. Weird but a good cheap fix.
