Conclusion: Great sub for the price, I can't seem to feed this thing enough power lol they look great and feeding 2 of them a 1000 watts a piece on a single coil and they slam! It makes my doors flex lol but on the other hand these speakers at heavy as hell! I was a bit sceptical about buying these but now I couldn't be happier with them. Just make sure you break them in!
Conclusion: I currently have 2 of these subwoofers and im extremely impressed. When i installed these in my subwoofer box (also bought on this sit) it was too big for my trunk. I proceeded to throw them in my back seat till i came up with a plan to get them in the trunk. When i first turned up the subwoofers (back seat) alot of air was beeing pushed out the ports but my mirrors on and in my car barely shook, i was very disappointed.
Conclusion: Top notch woofer for a great price. Has great lows but don't expect any higher frequencies like over 150-250 hertz thanks to the heavy voice coil cap. Could use better quality control but I think that's the reason for the price. I am running my MOFO 122X on 900 RMS in a sealed 1 cube box and it throws over an 1.5 inch, shakes everything. On a second note about the voice coil cap, it does work great as heat sink.
for the money it was ok, but do not try to give it the rms.

Summary: the sub lasted 3 days, the box was built to power acoustic specs. it will not handle what the rms states. maybe half of that 600 to 700 watts. I run RE Audio in one of my vehicles, and Sundown in the other. There is no comparison at all.
