Default some advise

ok, I am about to buy a 2000 watt RMS amp at an unbleavble price. But I was just wondering if it would hurt the amp any to run it at a low voltage because I have a single 200 watt RMS sub at the moment.

Thx for any advise

You could set the gains all the way down and give it a really small input voltage, but it would still be giving a lot more power than what your sub can handle.
I don't think the amp will like running at much lower than 10 or 12 volts, but I'm not sure. Maybe Jim Truett or wayne or someone who knows more about amps can help you out on this one.......

Could I just keep my volume down on my deck low with my gains low, and not hurt my sub any? I do plan on getting a betetr sub in the near future.

probably

How many ohms is your sub and what are the specific RMS ratings for your amp?
Cause I'm guessing that your amp is only going to put out that much power at 1 ohm. So if you have a 4 ohm sub if wouldn't be seeing anywhere close to 2000 watts.
Otherwise if you have a dual voice coil sub you can run the coils in series to get a higher resistance so it won't be getting the full 2000w.

Im not too sure on the specs of the amp. I havent gotten to see/question about it yet. But your prob right, 2000W at 1 ohm. My sub is 4 ohms and single voice coil. But it would be easy to get another sub (smae kind) for cheap. Other than wireing in series, is there anyother way of adding restence?

Be careful of the voltage that you give the amp, because if it's too low than the amp will go into protection because of it. Usually any lower than 12v and an amp will go into voltage protection.

at 8ohm, the amp would be giving each sub about 125 watts. IMO, its a waste to buy such a big amp and use very little power that it provides. get an amp that does about 400-500 or so watts at 2ohms. or find a 4 channel and bridge the channel together for each sub.
