I have an old ass Targa Competition amp 100wx4 (i dont even think Targa exists anymore) running 2 kenwood 12" sealed box subs and my pioneer head unit running everything else. I built the boxes myself and I have plenty of room, so they are way bigger than they need to be, so the lows are distortion free. I think I entertain more people on the street than in my car.
