Well, many have had isues with CD player but I have fortunately have not, however all speakers are blown and this is what I have decided to do. Please give thoughts....

Keep OEM head Unit(It works fine and really don't want to loose CD changer)
Go Components Infinity System in Front with 6.5 Woofer, SailTweeter
Eliminate rears, just disconnect
Add Infinity Self Powered Basslink 10 Subwoofer. Under 500$
