I installed them today in the back of the rsx in a sealed box. They are running off a jble 1200.1. So far I havent been pushing them too hard because i want to break them in properly. They are running off the stock head unit spliced into my rear speaker. They wont get very loud but when they do they shake your whole body. They are very accurate and have great response to the fast bass lines. I'll be getting a real head unit next week and be ready to push these to their limits. Sorry for the crappy pic, it was taken at night with a camera phone.
