Like said you can, but you risk a lot doing so. Your health as well as the amp not having enough voltage and amperage. Get a couple of MegaWatt 50 amp power supplies and run that thing right. Good amp as long as you don't overdrive it!! And it needs some amps and good voltage. JMHO's. Read up about using car batteries indoors. Not a good idea. Anyways. If this is a base, focus your attention to getting the antenna setup as best as you possibly can and don't skimp out. And that goes for the coax and all other related needed parts. It pays to have a good antenna setup. You'll find you don't need a bunch of power when you have a good antenna setup. And with the DX being dead, if the conditions aren't there, doesn't matter how many watts you're running. Just some food for thought. But truly, focus all your attention on your anrenna system and you'll see what a good one can do. Good day.
