Fantastic on top of two Rockford P3s
I purchased these a couple weeks before throwing two 12s in my 4dr, 2003 Grand Am. I have the 6 speaker system, all originally Delco stock. I'm using a cheap Pioneer DEH-5500, and no amp, and they sound amazing. With my HPF set to 125hz or 160hz, depending on the genre, and the subs catching everything lower, these things are clear as can be. I did notice that the stock 6x9s actually produced more bass than these, but they don't compare to these Kickers in sound quality. Doesn't really affect me since I have the subs. A great buy if you have little desire to pull bass out of them.
Pros: -Super clean mids and highs when used with a high pass filter -Look great -Really durable -Easy install
Cons: -Less bass than my stock systems 6x9s -A little more casing around the magnet would be nice
