    Ok guys, I need help choosing the right setup. Here is some up front info. I already have a 4 ohm, Ampeg SVT-410HLN (500w RMS/1000w Peak). In the future I am planning on either adding a 1x15, 2x10, or 2x12 extension cab. However in the mean time I have this Ampeg cab that the power amp will be running. I already have a preamp laying around so that is not an issue either.

    So I need a power amp that can run this Ampeg cab for now and then I can go stereo once the second cab is purchased down the road. Lets assume the second cab will be able to handle similar loads to the Ampeg for simplicity sake.

    So what are your recommendations? QSC? Crown?

    QSC, or Yorkville power amps if you can find them.

    I have experience with the Crown XLS series. Excellent power amps, and very affordable. For a little more cash, you can go for the XS series. Check them out at http://www.crownaudio.com/amps.htm.

    Nothing against the other brands, it's just that I am a Crown guy.

    thanks for the responses guys.

    bill h- If I went with the 2402 would I just run one side of the stereo side into the Ampeg for now? Correct me if I am wrong but that would be putting 700 watts into the Ampeg right?

    yes, you can run one cab with one side of the power amp for now. i am not sure on the ratings for that amp, but if it is rated 700 watts per channel at 4ohms, than that is what the Ampeg will be getting.

    Thanks Mike, I notice a bunch of guys that run way more power into their cabs than what they are rated. How do I know how much is safe? What is a good rule of thumb when matching amp power to cab capacity?

    I see Josh. So it is ok to "overpower" a cab as long as you are not trying to make ear drums bleed. So I could safely run around 700-800 watts into my Ampeg as long as I dont have the volume on "10", so to speak.
