I have a Palomar 350XL blue face look like Cobra 350XL with 2x 2879's in it I assume I should have 2 watt or less dead key ad 20 to 30 watt PEP? The same for the white tornado 225 with 2x MRF455's? Does it mate how many finals the radio has if I can get the wattage down? Is 20 watt PEP to low? I appreciate any help, I am new to amplifiers Thanks
