How Many Amps Does A Vhf Radio Draw. The Icom A120 is a PEP 36 watts VHF radio with a maximum transmitting current is 5 Ampsreceiving 4 Amps. It works at around 50 watts RMS and will draw about 4 amps of power at a.
Looks like it draws max. To run a 138 vdc device at 40 watts. Well 100watts at 12v is almost 85 amps.
If you want to power only the tweeters or speakers a 2-channel amplifier will be good enough.
Most 50 watt radios draw more than 10 amps on transmit. Well 100watts at 12v is almost 85 amps. A 25watt 2m VHF radio I use draws up to 12 amps on TX. On US cars the fuse for a cig lighter is 15 amps or more.
