The speakers are still on their way from CA to VA. next week review!
3 July 2014
Summary: I bought four of these for my 2012 Optima. I have a dedicated Kicker Mono-block sub amp, model 300.1. The neat thing about Kicker is you get a certificate with it's actual tested RMS output (at less than .2% distortion). Mine came in at 327 watts RMS through one channel into my 2 MTX 10's sub box.
Good, inexpensive speakers for better than stock sound.

Summary: For the price, these speakers work fine. They are the lowest end Alpine speakers you can buy, economy speakers. If you purchase them knowing that they aren't amazing, you will probably be satisfied with the buy.
