I just picked up a rockford fosgate p400-4 amp and now I need to pick 2 sets of 6x8's for the doors. I will need coaxials since I don't have a sub. I need help picking between these sets. If I've missed any, please let me know. Here's the amp specs: amp specs

Please help me choose, I can't decide. I assume all four should be the same too?

i have the alpines in my car, great sounding speaker. Have them hooked up to my alpine pdx f4 which puts out 127watts rms. They handle it with ease and sound loud and clear. Very impressed with the speaker.
