I just installed my Kicker Hlcd's this weekend you will be happy !!!

Because I already had the amp I used a kicker 350.4 it puts out 175 per channel in bridged mode I am only running the 2 mids if I upgrade to 4 I will need a new amp

For your set up if you are planning on going with the 2 tweets and 4 mids the 650.4 bridged would be a good choice 320 watts per channel leaving some head room even for the 6 speaker setup
