Iv always been into kicker. Just love how smooth they sounds at every frequency and they are hard to blow. I just replaced my pioneer for kicker and way much better. I'll always recommend kicker with confidence.
Pros: I love the material they use and the stitching. Very good quality just looking at them. Good sound response and clarity. Nice that they carry products for every type of budget.
Cons: Don't really have any cons except the price on some of the higher end equipment. You get what you pay for though.
