This is a review on JBL GTO928 and JBL GTO628 (6x9) (6.5). I would like to cancel out all the reviews about the lack of bass. These speakers have very very very good bass, beats stock speakers by a long shot and you can run them at higher volume.
DON'T MIX THE WIRES!!! The speakers will run regardless of which way you install the wires, but they will run properly only in one combination, you have a 50/50 chance, test them out. You will know when you got them in wired right, there will be good bass, they will not rattle and when you turn them up higher you won't hear plastic bending and muffled sound. Don't confuse rattling with poor installation- these are heavy and hit hard, I put my (6x9) on some heavy bolts and nuts. I would like to cancel out all the reviews about returned and broken speakers. If you have wires backwards and run them at moderately high volume- they will soon stop working (BROKEN), YOU BROKE THEM, THERE IS NO QUALITY PROBLEM HERE.
BOTTOM LINE: I have no sub, I have no amp, I have aftermarket Pioneer deck with navigation, same wires, nothing extra, everything else is stock except for drilling holes and finding the right bolts to fit the back speakers. 6.5 inch speakers are supplied with good installation brackets- use them, whichever one fits best, use your imagination. With proper set up in the equalizer and bass control- THESE SPEAKERS MAKE THE WHOLE CAR VIBRATE. (Chevy Malibu 2009) Good Job JBL.
To consumers: when in doubt- [...] for answers. Good Luck!!!
