The strengths of these speakers is their sound reproduction and their marine certification.
The peak power handling of these speakers seems to be overrated.
These speakers were great for the first 7 months that I owned them. Had them attached to a 2 way 100 watt amplifier. They reproduced sound like I have never heard before. I purchased them because of their power handling and their marine certification, because I have a two seater convertable. After 7 months though both midrange speakers stopped working at the same time. Fortunatly, I was able to get replacements from the dealer and I am back in business.

hard to keep clean..gap around center logo catches dirt..
i chose this speaker because of the look of speaker grille..it matches my car really well.. i am running this to 120watt 2 channel amp and tuned it real good..turned volume all the way up and i don't hear any distortion, no nothing.. bass wise, not better than rockford fosgate p seires..but that is not the point..my mono amp and subs are taking care of all bass..

beautiful speakers, great clarity and loudness, very impressive midbass for a 5.25" speaker
Nothing that didn't come from me putting these where Chevrolet never intended a round speaker to go..
I got lucky and found a set of these on sale... Turns out, they're well worth the standard price. Getting them to fit in place my stock 4x6s was a bit of a pain, but that was to be expected. Dremel for the win. ONE woofer/tweeter gets easily more than twice as loud as BOTH stock speakers with gobs of clarity that stock speakers can't touch. I have these in my dash, and they hit a little higher than the 6501s in my doors... The overall sound from the two is magical. I couldn't be happier --then again, I haven't amped them yet.

Speakers sound great when you come keep everything working.
weak conductor wires breaking loose on the cross over board.
Love the woofers and teeters for the db5251 series but the cross over have too many problems the conductors keep coming loose, which makes the woofer stop working. I'm not the only one that's having this problem!
