Hi guys, I’ve had a power amp of Crunch for a long time and that’s a Blackmaxx MXB-4150i . As I’ve already gone 2 subwoofers with it and I’ve now switched from 25cm to a 30cm sub I wanted to ask what kind of power amp really does when you’re off the data in the net. So with this power amp it’s worth 100WRms per channel, turned on 4 ohms (1+2,3+4) 600WRms and turned on 3 ohms (1+2,3+4) 900 WRms ? Does that work? at the moment a 30cm 4 ohm subwoofer from Audio Systems Connected with a load of 800/400W and the part gets quite sweaty Even if the power amplifier has no gain at all and all filters are on. Therefore I always have to On Radio In addition to the sub on minus places. Is this permanently Ok for the sub or not, Shouldn’t the power amplifier be a little weaker so it fits performance Technically to the sub ? – 400w Rms Sub on 400w Rms power amplifier ?
