I installed (ok, well my buddy installed) the jbls today. They sound good, but not night and day like i imagined in my mind, lol. I installed the drivers side front first, and compared it to the stock bose switching back and forth between the two and the jbl did sound much crisper. All in all im happy with them and would do it again if i had to do it over. Keep in mind my stock speakers were fine and still sounded good, so if u have blown or busted speakers the jbls will make you extremely happy.
One thing we did notice and may have just been low batteries in our multimeter, but the rear doors show closer to 3 ohms, the fronts were clearly 2 ohms but the rears fluctuated between 2.8 -3.5. They sound good though, plus i dont play my music at crazy volumes anyhow, so hopefully theyll last a while and wont cause any issues.
