i ran a home brew FM 10 meter amp on a HTX-10 300 watts out @ 29.600 to a 9 foot wip on the trunk of a 79 cady there is no doubt you should have no problems with running a amp ..... i worked germany from the car.

That's a good combination. I have that exact same setup in my wifes car.

That is one of very few radios where you have full control the sideband power from the front of the radio. The radio itself has easy capabilities of 36 to 40 watts of output.

One of the neat things I like about this radio is the fact that what ever the maximum output power is in F/M, that's what you will also get on sideband. Into a dummyload, mine shows 38 watts and that's exactly what I get when in the sideband mode.

To answer your question, put a RF power meter on the radio and go to the F/M mode. Key the mic and turn your power knob up to around 15-18 watts and take note of where the power control knob is now setting because that's where you will always want to set it when using your linear. 15-18 is enough to easily drive that KL-300 to 225 watts or more. Don't try to drive it to its maximum. It will overheat too quickly. Heat is the biggest enemy of RF linears.

We have been using this setup in her car for about two years now with no problems at all.

You didn't say if you are or not but if you use a mag mount antenna with a linear, all I can say then is hope for the best but expect the worst. Its never been good practice to run a RF linear into a mag mount antenna because of the lack of a true ground. All kinds of weird things can happen---especially with your vehicle's electrical system.
