Hi all, An outdoor event is coming up where we don't have access to an electrical outlet and a generator is too loud. However, we want to be able to have a wireless microphone system (using a lavaliere) and at least one amp/speaker so that guests can hear what our Speakers are saying. I was told that an option is to get a (deep cycle) battery and directly hook up a power inverter to it so that we can then plug our amp/speaker and microphone receiver into it. The event is for a crowd of 40 people, so it doesn't have to be TOO powerful of an amp. I'm not sure how many watts/amps this would all take, but could someone suggest the type of deep cycle battery and inverter we'd have to get (ie how many watts is enough for each). The different watts for both the battery and inverters out there are confusing me, and perhaps I don't need as much as I think. Thanks in advance!
