JBL rear speaker replacement
I have a 2007 Toyota Camry Hybrid with a factory JBL system, without navigation. I want to replace the rear speaker ( previous ones were sun baked and I tossed them(!!!))... Do I have to use the original 6 x 9" JBL speakers or what? I installed a pair of 4 ohm speakers and it sounds like crap! ny help will be appreciated!
