Had this sub for several months, sounds fantastic in a sealed box. Have it bridged into a Rockford t400 so it's only getting about 246watts. Handles much much more, hoping to upgrade my amp soon so I can push at least 600w into it. I would strongly recommend powering this sub with at least 400w. As previously mentioned it sounds fantastic in a sealed box, very deep and rich bass sound. However it doesn't rumble the car too much due to its box and low power source. Nonetheless I am completely satisfied and would recommend RE audio subs to anyone. On a side note, my friend has two alpine type r hooked to a 1000w amp. His definitely pounds harder but seems to have a limited range and doesn't puncture your ears with rich bass as my RE does. Again, I'm sure my sub could surpass my buddy's alpines in every aspect if I provide adequate power.

I got 2 of these subs running on a Hifonics amp at 2 ohms getting 1100 watts rms which is underpowering them by 50 watts a peice and let me tell you, I thought my trunk was gonna break off. These subs are clear and have some nice excursion. I pulled into a underground parking garage the 1st day i got them and had people covering their ears and giving dirty looks and all i could do is smile :) haha. Overall i would recommenced these subs, wish i could of got the 15's but dont have room for them. But these 12's already pound your chest and make it hard to breath sometimes so im a happy customer.

i have one of these on a RE audio amp and it is the cleanest bass ive heard from a car ever. when you turn up the volume, you cant hear yourself talk and its like a kickboxer is using your chest as a punching bag. its in a ported box tuned to 35 hz and i think i have about 500 watts rms running to it.
