[QUOTE="zako, post: 7762640, member: 629735"] I don't have experience with sony xplod. It seems like the general opinion is that their product are very low end, except for a product or two. I wouldn't be surprised if Hifonics Zeus is much better. I would have preferred to spend a little more coin and buy PPI P1000.1. Actually, when there is a good sale, they cost about the same as Hifonics. Sonicelectronix has them on sale for something like $170 until a few weeks ago. Having said that, I personally have not felt a big difference in sound quality after moving my subwoofer from 250watt Class A/B amplifier running at 2ohms to a 450watt Class D amplifier running at 2ohms. Sure, the new amplifier has more potential to "hit hard", but at normal volume level I can't tell a difference. I do like it that the Class D amplifier is more forgiving in terms of heat when I drive it hard for long periods of time. I even have it mounted on a side of sub woofer box with no issues with overheating. [/QUOTE]
