    I'm using this Stewart amp as an example, since the specs are in a nice, neat, easy-to-read format:

    OK, assuming a pair of 8 ohm cabs resulting in a 4 ohm load, this particular amp will give me 350W using one channel, and the other channel will be idle, right?

    Or, can I put one cab on each channel, and have 200W into each 8 ohm cab - but how and why would I want to do this?

    Also, I can bridge the amp and have one channel at 1200W with the same 4 ohm load, correct? (Poof! Roasted Bag End!)

    I'm tying to learn here, so please be gentle - I'm trying to plan future GAS attacks. Spending a few hours in the archive has left me with more questions than answers.
     
  2. Yes to all.

    Why would you run 2 channels for 200 watts each as opposed to 1 channel of 350 watts?

    1) 400 is more than 350.
    2) You want to control the speakers seperately.
    3) The damping factor is reduced as you connect multiple speakers to an amp. The higher the damping factor, the cleaner the sound.

    How?

    Usually, you can use the inputs to chain to the other side. So if you run an XLR cable for your signal, you can use the 1/4 inch input of that channel as an output and connect it to the other channel's 1/4 inch input(Shielded cable only).
