I wouldn't buy Kicker woofers period, they have a low sensitivity and a high wRMS. More watts does not mean louder music, and only means you have to buy a more powerful, more expensive amp. Neither of them will "POUND" in the sense you're expecting. What is your budget range, I can give you a list of some manufacturers that are a better bang for your buck so to speak. On the downside to all this car audio is completely subjective, what sounds like sh*t to me, can sound great to you... Feel free to email or message me on yahoo.
