the one coil is the only thing hooked up, we tried to solder the leads, but it still wouldnt power wired in parrallel, so that coil is getting the 1050 and thats it. id go as far as saying it could handle 2000 with ease, cuz it took this relatively well. the type r, it got the same power and took it even better. of course that was 1050 on the whole sub, not just one coil. that thing was dumb loud IMO.
