Ok so I have had my 2008 Avalon for a month now, and while the JBL system is decent it can always be better. But after searching I am unable to find any specs on the speakers to see what my best plan of action will be, all I know is that the midbass is 6 1/2" if I am correct but no idea on the tweeters and not sure of impedance, power ratings, etc. If anyone has any info on the speakers it would be much appreciated it is the 12 speaker JBL oem system installed.
