overall, i like them for the price i got ($120 on ebay? it was about 10 mo ago). when i was just running a HU and speakers, it really gave out nice midbass. some buddies even mistaken that "midbass" for a subwoofer. *i had it on high bass heh*. it wouldnt crackle or distort even when i turned it up to 90% volume (with the bass level from the HU off of course). keep in mind, these are the first set of 6x9's i expierenced with in my vehicle.
