These Slap!
Okay, by sayin these Slap! I mean on my stock head unit I can turn them up 90% of my stock listening volume, and they just go to town, with solid bump in the bass at least 2.5x better than stock, and will only get better when tuned on an amp, with a higher quality head unit. But these for there price will not be beat. I can't wait to pick up a pair of the XQS65KIT for the rear. (Nissan was confused when developing SUV's).
Wow! These things rock
I have these on a 100 watt rms per channel amp and they get loud. They don't distort and have good mid bass. The tweeters took some work but found some pods to mount them in and set on the rear deck in the car.
