I went by a car audio place today looking to add a sub to my car. The guy there was pushing the Clarion WQ2510D. When I came home to do some research on it, nobody has done any reviews on it. I've look for 3 hours and haven't found anything. So my question is has anybody dealt with Clarion subs. Are they any good? Is it going to crap out on me after 1 month of use. Any feedback is much appreciated.
