Definately my friend your Factory fitted component speakers will work more correctly and give good sound & bass with the ALPINE CASSETTE PLAYER INSTALLED in the new XLI'S.
Other then that if u want to put some orginal component speakers I would recommend you to install 5-1/4" Compnent speakeers of TS-GS134IR 130WATTS 1500-2000 Rs PKR OR Crunch GTS 5.2C,5.2Ci OR 6.5C 1600-1800 or INFINTY 5010 CS (3000-4000) PKR OR INFINITY REFERENCE 6020CS (4000-5000).PANSONIC DA 5723 OR DA1323These are the prices of orginal Componets Speakers.In whic the most cheaper ones is Pioneer (1300-1600).I am not here to confuse you but wanna tell you these are really the orginal COMPONENT SPEAKERS PRICES....
Other then that if u can get Polk audio or Infinity or Fusion Or Kenwood Specaill Excelon Series in the mkt then it is better then Pioneers and others.[/highlight]
