wtb/wttf amp that goes low ohms

Judging from the list of jacked up amps you have, I don't think you should be running anyting at .25.
With that said though, fix that 20.1. It'll run .25

it would be better to just wire the coils in series to 1 ohm, and just get an amp that outputs lots of power at 1 ohm. this will give you the boom you're looking for. there are tons of amps out there that put out what you are looking for and more at 1ohm. there is no benefit to loading any amp down to a quarter ohm, even if they are designed to. at that kind of load, efficiency is bound to suffer drastically.

if you already have an amp designed for max power at 0.25 ohm, great, but if not, don't go looking for one that does. look at it this way. if you could make the same amount of power at 1 ohm vs. 0.25 ohm, it is always better to get that same power at higher impedances. there are reasons they don't really make many amps these days that go down to a quarter ohm. for one, lower impedances equals lower efficiency, as previously mentioned. damping factor also suffers, though whether its audible or not may be debatable. lower efficiency means higher stress and heat on the components. back in the days when 0.25 ohm stable amps were more prevalent, they were designed as 'cheater' amps. tight power classes in competitions meant competitors could use amps rated at 50watts at 4 ohm and actually have 800 watts at super low impedances. sound off competition classes have changed because of this very reason. today, there is really no good reason to make amps that go down to 0.25 ohm.
