Yes, I can tell a difference. I think people buy these thinking it will make their speakers sound like a sub with lots of bass. If that's what they are looking for then it's not gonna happen.
I can tell a big difference in the sound quality. The speakers sound with more clarity and fullness. And my dash dosent rattle anymore! I am running 4x6 kickers as opposed to 5.25's so I can't comment on how it would sound with them. Overall I'm happy with the purchase. I would recommend them to anyone. Hope this helps!
