this are with out a doubt my favorite speakers! i picked up a pair for under $90. and when properly installed and powered (crucial) they sound like a $300 set. i have installed the DB series in 4 different vehicles i have owned and never once had a problem. i highly recommend these. i was surprised at the amount of bass these pumped out, but like i said, being adequately powered is the trick to getting the great sound they are capable of.
