The 25 amp blew and not the 2 amp because that is where the juice got to first. When you talk it's getting flooded with juice for some reason. More than 25 amps. This blows the 25 amp fuse. The 2 amp fuse doesn't blow because it doesn't get a chance to get there. Sounds like you got a bad mike.... shorting out somewhere along the internals of the radio/mike. Try borrowing a radio from someone else and seeing if the fuse still blows. If it doesn't - get a new radio. If it does blow, check your wiring.

Use a 10 Gauge wire to power your radio. If you use a lighter wire, you will lose power and distance. You only need the heavy wire to transmit which is a two+ amp draw from your battery.

jusgrinnin - I only suggested that because I did it once. Thanx for making me feel better.
