Man i love this speaker i have two of them hooked up to 2 rockford fosgate 3000 watt amp and man they thump. I have had many speakers but these are by far the best. It hits all the notes perfectly and has almost perfect sound quality. If you can afford these speakers i would not hesitate to buy them right away. But you dont want to put them in a geo metro or something like that because you wouldnt have room and you would probably bottom out because they are so heavy. I was very pleased with them.:-)
