Sir, you are not to far off the mark..the more important factor being an electrical engineer is that the pac isnt rated for the extra heat. So it will catch fire... Or more acurately the componates are not able to handle the levels involved and thus will heat and if they dont fail due to heat then you will have a fire... If you want to upgrade do it properly and get the correct internal parts (or product) capable of dealing with such ignition requirements. The impeadance of the cable & Pac is more important than the resisitance and in line with the increased voltage and thus lower curr
