I just threw these in the back of my mustang yesterday. They're hooked up to a 400 Watt 2-channel and and they are crystal clear. At higher volumes the low end started to click but I didn't have any filters set up. At this price, Wicked buy. Can't post on durability yet as I've only had them for one day but they seem sturdy.

Once again, i made the mistake of buying these from a local retailer. Cost me $300.00. My deck barely puts out the peak power output equal to the RMS of these speakers. I really need to get an amp to see what these babies can do. I know they are capable of some extremely high quality and loud sound. For this price, HIGHLY RECOMMENDED!!!

I have these in the front door of a Ford F150 Super Crew. I did have to cut the top and bottom tabs off to install the woofer. The speakers themselves are perfect. I highly recommend an amp to power these. I had them powered by the HU but after hooking up an Alpine amp to these they showed there true sound.
