Max input is 20 watts. Have 3 of these amps (1452G, 2252G, 4452g). Over past twenty years. So-- good and bad: Good: If you are care full and don't overdrive, amps are great. You must use AWG 8 to ensure proper voltage. Recommend Astron Rs70 power supply. If you make a mistake, overdrive it, SWR's go up, you will blow them up. No protection on these amps at all. Buyer beware. And good luck trying to get it fixed. Problems are well documented on QRZ and Eham.
