electrical question on amp ratings
Ok, So I am doing the 12v part of the build on my cart and I have a question. Here is my situation I purchased a battery S.O.C. meter and it has a built in relay that converts to 12v. so you can tie in accessories to it and it will kill the accessories when the battery pack gets to 30% charge. My question is this. The radio I want to tie into it is rated for 18w X4 RMS and 50w peak. at the RMS of 18 I get 72w. total and the relay is rated for 3amp/90w Will this work or is the radio going to exceed the amp/watt rating if it hits peak?

Re: electrical question on amp ratings
forget about the output wattage... look for the current consumption specification either on the radio or in the manual. if the radio consumes more than a couple of amps, you can use the 3a relay to control another relay with a higher rating. say a standard 30a auto relay.
is the "constant" wire the fat one or the "switched" wire on your radio? -sj |

Re: electrical question on amp ratings
Ok that sounds like a good innexpensive solution that will solve any potential problems I will just wire my 3a relay to a 15amp relay and that will eliminate any questions then I will have enough room to wire the lights into it also. Thank you for the help.
