So im planning on purchasing a 350 watt solid state head (Crate Shockwave). And I came across this deal on craigslist for a 240 watt cab. So im wondering, what happens if the head has more watts than the cab? is it a bad idea to use a cab with less wattage?

thanks in advance!

Keep in mind that your amp won't be pushing 350 watts unless it's pushed to its limits. However, you usually want your speakers to have a higher wattage rating than your head. As far as I know you shouldn't use a cabinet that has been designed to handle less wattage than the head you're using to power it. I'm sure if the difference was very small it wouldn't be too harmful, but with a 110-W difference, you may cause some damage to the speakers. I'm not an expert, so hopefully someone else can add to that or correct me if I've made a mistake. Until then, here are some references to help you out:

Impedances? It will be 350 watts into some load (probably 4 ohm so they can boast higher figures). If the cab is 16 ohm and the amp is rated at 4 ohm it will be pushing more like 90W into it at full tilt.

Yes, just look at the specs for the amp they will say "350W into X ohm" and possibly say what it is into other loads too. Like I said, they usually quote it into the lowest possible load it can tolerate in order to inflate their power rating. It's not uncommon to see SS amps (of any type; hifi, PA, car stereo, etc) quote it into 2 ohm. It's an old trick.
