these are a great addition to changing the entire Sound Stage of your vehicle. the low to mid-range is precise and the high-end is very apparent. as much as I love these as a replacement, the tweeters are very delicate or they are not a very reliable driver. I have two sets of the 610c and they are in different vehicles. One is driven by me and the other is driven by my spouse. I have had one Tweeter failure in each vehicle. the systems are not used to turn up for loud volumes other than occasional "oh I like that song". other than that it is quiet listening. these are a very high sensitivity as well. I think that anyone who installs these in their vehicle will enjoy the reward however the high frequency failure rate is quite high in my opinion.

Huge improvement over stock
from Sacramento, CA
Massive improvement over stock 2012 Nissan Leaf speakers. Added tweeters directly to door between door handle and a-pillar. Looks like it came that way if you didn't know better. Let the OEM tweeters installed and no loss from doing so. For the price you won't be disappointed, but don't expect it to rattle the car next to you. This is the second set I've installed into my vehicles, and feel like its a good balance between price and improvement over OEM, yet simple enough you don't have to get into an entire system build.
