I am looking to get these speakers for my P5 when i buy it over this weekend.

Infinity Kappa 572.3cf 5"x7" 2-way Speakers
Large C.M.M.D. woofer • rubber surround • C.M.M.D. dome tweeter pivots for better imaging • outboard crossover included • 2-100W RMS power range • 3-year warranty

Infinity Kappa 63.3i 6-1/2" 3-way Speakers
Large C.M.M.D. woofer • rubber surround • C.M.M.D. dome tweeter • EMIT supertweeter •outboard crossover included •2-75W RMS power range • 3-year warranty

Are these a good choice ?

 

I personally like Infinity car speakers, particularly the Infinity rounds--I'm not quite as fond of their ovals, though I must admit I haven't had a chance to audition BA's or JBL's yet.

As for going with Kappas, it depends on whether you're planning on upping your power, either by adding an amp or replacing the current head unit. The Kappas really want more power than the P5's head unit provides. If you're not adding power, save yourself some cash and get the Infinity Reference line--that's probably what I'll do when I get time to do it.

The best advice, of course, is to go find someplace and listen for yourself. You should audition with a power setup that's comparable to what you expect to have. If you're planning on keeping the factory HU, then just pick the cheapest Panasonic HU they have and don't add any extra amplification.

 

i like the ref's better than the kappa's, but that's just my preference. they don't handle as much but the sound is smoother. they're pretty good for what you can get them for. eBay and other online sellers offer really good prices on infinity stuff.

i'm sure depth wise they'll fit. are you doing your own install?

 

The 6.5 are nice but they need an amp, stay away from jbl for component, my cerwin 3ways help balance the system and make up for the midrange that the 6.5s lack.
