I am using a Crown XLS1000 power amp in my rig. I've had several people on forums tell me that this amp is fine for bass when I brought the subject up. I run it in bridge mode and it supposedly will put out 700 watts at 8 ohms, 1100 at 4. I'm using one 8 ohm Seismic Audio 4x10 cab which will handle 800 watts RMS. But it seems like I don't get any significant volume until turning it up past 12 o'clock. Anything below 9 o'clock is pretty much bedroom levels, when I've played amps before where as soon as you push knob up a little, it practically explodes with volume. I mean, it's loud enough for playing against drums, but I feel like I should be getting so loud that its uncomfortable to be around given the wattage on this thing, and its nowhere near that. I'm worried about the potential for hard clipping running the levels as high as I am. And I want to get stupid loud, as I play stoner doom metal. Granted, I'm using a Line 6 Pod 2.0 which is meant for guitar (I'm a recent convert to bass), and that's probably part of the problem. I max the master volume on the Pod, but it doesn't seem like its putting out the kind of signal that a preamp should to really drive a power amp. I'm going to get a different preamp soon, but I just wanted to make sure there's not something wrong with the power amp, or that I'm not doing something totally wrong on my end. Does anybody use this particular power amp? Anybody have any ideas as to the issue?
