I got a mtx rt2400 amp pushing out 400 watts when bridged. I'm going to hook it up to a mtx 4000 sub just for temporary purposes, but the sub has an rms of 200. Is 400 watts gonna blow it up?
Soon I'll be getting a 7500 mtx sub or a comp VR that can handle the power..
also this amp has a 60 amp fuse, and my other amp for my highs has a 20 amp fuse. Is 8 gauge off the battery ok, or should I get 4 gauge ran until the distribution block?
4 guage. And if you're careful, then you'll be fine. It's usually safer to overpower than to underpower, because the amp has less chance of clipping at a set volume level, just because it isn't straining as hard. If you hear distortion then turn down the volume.
