At that price, I'd be an idiot not to recommend that to my friend who is soon going to be upgrading his subwoofer and main speakers I have two good choices of amplifier: a 500-watt Parts Express Class-G (Sunfire) plate amplifier of the same type that I am using for my own DIY sub, or a 380-watt amplifier. Which option would be better for the Megawoofer? I imagine the Megawoofer has a fairly low inductance as compared to the 12" Stryke Audio AV12 I am using for my personal subwoofer. Also, the flexibility of cabinet aesthetics associated with a kit offering appeals to me. All I'd have to do is make sure to maintain the internal volume of the enclosure and the dimensions of the slot that the passive radiator is loaded to.
