Hey all, I did the forum searches and could not find any info about the difference between stock JBL speakers vs stock non. Has anyone that has non JBL head unit ever switched out the speakers to JBL? In the searches I see that there are several aftermarket speaker options to consider, some requiring additional amps and others using stock head units with varying results. Over the years (alot of them) I've installed numerous audio upgrades starting with FM converters and 8tracks in the 60's and 70's to headunits with cd's, usb ports and bluetooth capabilities, some with additional amps that higher quality speakers require to drive for optimal performance. What I'm asking is if I can locate and install JBL's would there be any sound quality difference? My intention is to dynomat the doors during the installation process which I'm sure will help the overall tinny sound when closing same. I don't want to change the stock headunit that works ok (except the way toyota has chosen for access to music on a stick) to aftermarket. If anyone has any info it would be greatly appreciated. Thanks
