Infinity Reference components

Anyone have experience with Infinity Reference 5x7 components (6800cs)?  I'm looking at putting them in a 2004 Ranger supercab with the same brand 5x7 two-ways in the rear doors.  All will be powered with an Alpine 9830 hu, the Alpine F240 40x4 RMS amp, and the Infinity Basslink 10" powered sub behind the seats.  I'm not looking to win any competitions or make my head explode.  I really just want a system that sounds good for the money, and these products seem to meet the money part.

How will these speakers sound with 40 watts going to them?  I would rather not waste my cash on speakers that are only marginally better than my factory ones, so if I have to I can upgrade to the Kappas and maybe get a bigger amp.  But I would also not like to spend lots of money on this and I don't want to pull too much power off my alternator with just the sound system.  Simple is good for me.

I love the reference series stuff.  I think its the best bang for the buck when putting in a system. A few things though...Their smaller speakers sound fantastic running off stock power, but if you go to some of the 6x9's etc.... you may want to invest in a small amp, but its up to you.  i personally just put bass blockers on each speaker, and run a sub set-up and have always gotten crystal clear sound with nice bass!

IN SUMMARY---GREAT SPEAKERS
