[QUOTE="jonboylaw, post: 526459, member: 17621"] Check the spec, I expect they are using max RMS power. This would give: 200w x 0.707 = 141.4W 141.4/13.8 = 10.25A Anyhow, if they have a 10a fuse on the supply then you could use a 12 or 15A fuse in the box as you really want to protect the wiring from shorts. If it is a 10A fuse on the output stages (to the speakers) then this is a different kettle of fish. In this case P=IsquaredxR Assuming a 4 ohm load: P= 10x10x4 = 400W Sent from my GX64 SatCom phone using Tapatalk [/QUOTE]
