I can't say that I've never had any kicker products because I have. They used to make decent stuff. The current stuff isn't terrible but there are WAY more companies that make just as good and most of the time better products for less money. I'm all about getting my moneys worth, :shrug:
Kicker is also sold in Walmart now, all Kicker fan boys around here are fgts and think their shit does 150s with 2 10s, and I don't like to follow main stream companies that over charge.
No Sundown here, I've had 2 Sundown setups in the past 2 years and was very impressed but once again there are many other companies I'd run before Sundown even.
Another thing I really liked about Sundown, DC, and etc were that customer service is on point and they're always there to help out.
Edit: To the OP do you have space for true sub setup or no? The hideaway isn't the best option if so. You can have a single 8 and have a much better setup than a hideaway. imo
