I am trying to decide between Infinity Kappa's or Polk Audio 5x7's for all 4 doors on my 2006 SCrew. Anybody have any suggestions as to which speakers are going to sound better?

 

Best advice I can give you on this is to just go to a store & take a listen to them yourself if you can. Take along a cd of what you normally listen to & this should give you a rough idea. Not everyone hears music in the same way. You'll have 10 people that like this one but 20 others that don't. Your ears have taste buds just like your mouth. This is how I like to look at it. Better to take a listen if you can & let your own ears be the decision maker. Just my .02

 

one set of 6.5 diamond audio or rainbow components up front would be your best bet. polk and infinity's speakers sound pretty blah and are basically entry level speakers plus 5x7 woofers sound like crap no matter how you cut it.

 

I have Kappa component speakers (4) in my Passat an in my Grand Cherokee, and they sound fantastic. I just got my F150 Crew Cab and am not ready to put her under the knife ust yet, but have been thinking about it, and will stick to Kappas.

 

I 2nd the Rainbow suggestion. They will out perform and sound better doing it at the same price point of the Infinity Kappas or the Polks.
