PPI is **** now. I know you are inquiring about component speakers. No two brands sound the same and what you think sounds good may sound like crap to another. The point is, if you are able to, visit some car audio stores and listen to some different brands. We can suggest brands that are not crap but that doesn't mean you will like how they sound. I have listened to similarly priced JL Audio and Focal on the same power... the JL's were 6.5" and the Focal's were 5.25" components and the Focal's sounded WAY better to me. Kappa's are pretty darn nice, I have had some and enjoyed them. What has done you good in the past may I ask?
