I have two of these in my car man do they hit if you sit in the back seat you can actually get a massage. It sounds really good I have them in a mediocre box right now but it doesn't hesitate to shake the house. I park down the street and I can still hear the bass shaking my house I feel bad for my neighbors for keeping me up with their music at night now it's my turn! But really these do not need much room to make themselves heard they are loud i like how they are made air suspended but these cannot handle more than one thousand rms for sure they will start smokin and eventually burn so keep it exact or less than 1000rms.

I bought this recently and its def worth the money and will beat any other sub in its price range. Im only pushing 600 rms right and its like perfect. Cant wait for my new amp to see how good this baby really is. Must buy!!!

I have 1 in a 2'sq vented box with actually a 1600watt redline amp powering it(set at 1/4 power running 8ohm) and that sub rocks for the whole ride to work and back home. Amp never gets hot, sub sounds clear the entire time which is great no overheating distortion. For $125 this sub is actually a decent sub yes not the greatest but it is also not over $150. I would recommend this sub for those who are looking for clarity not setting off car alarms as you drive by. (and if you like that stuff then spend the money and get what you pay for) P>S> been installing systems for the past 17 yrs heard LOTS of speakers...........
