Tuning 800W?
Aside from wearing ear plugs, does anyone have some pointers for tuning an 800W two speaker system?
I've got a Sound Digital 800.4D Evo amp and two Beyma 6CX200NdN's all through a Rockford Fosgate DSR1.
I set the voltages at 20 VAC for the horns and 40 VAC for the parallel bridged mids.
After that, I wound up turning the gain on the horns all the way down just to be able to get above 1/3 volume. I'm also getting a slight hum at zero volume. I feel like I'm doing some wrong here...

did you set the crossovers for the speakers your using? Also when you set the dsp up what did you pick for input voltage?

I used the American Hard Bag setup file and changed my DSR1 outputs to front tweeter and mid bass with rear subs (or it might have been rear full range?). Since I'm only using the front channels, I didn't think the rear output mattered. I set the DSR1 to high level input. The input setup is essentially the same as it was with the NVX2 and Infinitys.
The outputs from the DSR1 are:
Channel 1 & 2 - Front mid bass - connected to channels 1 &2 on the amp - bridged outputs 1 & 2 from the amp to the woofers in parallel
Channel 3 & 4 - Front tweeter - connected channels 3 & 4 on the amp - outputs 3 & 4 connected to left left and right horns respectively
The crossovers on the amp are both set to full; I assumed that the DSR1 was handling the crossover function (should I set the crossovers on the amp in addition?)
I think it sounds good, but I'm sure there's lots of room for improvement. I'm also a little confused that I had to turn the gain for the horns all the way down. I feel like they're being over driven, although I really have no basis for that "feeling" since this is my first time playing with this type of setup.
This is kind of a new arena for me, so I really appreciate the feedback and guidance.

Outkast, yep, you nailed it. I was assuming that I had already set the crossovers, but nope...
I set them to 2.5 kHz @ 12 dB/oct for the HF and 70 Hz @ 24 dB/oct for the LF, and it made a world of difference. So, now I need to go back and readjust my target voltage output to establish a starting point again.
I didn't get this far into the DSR1 with my previous setup, so I'm still learning what's available. It's pretty sweet that I can cut the mids or tweeters off to be able to hear the other channels and adjust only that one. Also, I wound up dialing the master volume down to around -14 dB to give me more range of control with the volume on the HU.
Should be able to figure this out eventually, but I'm learning as I go.
Thanks again.

Good you are getting a handle on it. What Outkasts second question was referring to was the Headunit Sensitivity setting in the DSR1 setup wizard.If you're still feeling like you're over driving your horns try dialing back the input sensitivity. You should then be able to get closer to your target voltage on your amp gain adjustment.

That's just a "high level / low level" switch, no?
Edit: I did step through the wizard, and if memory serves me correctly, there was an option to select "high" or "low".

it should ask you like 1 volt, 2 volt, 4 volt, etc.
