they dont draw that many amps, i would recommend a thicker 12v constant (yellow wire) and a thicker ground......because before i replaced my friends the illumination on the hu used to dim.Sorry, I am new here. What do you mean by "destroyed your car's electrical"? I haven't seen any tests of these powerpacks but I couldn't image them being that significant.
ran 12 gauge power and ground and it took care of problem i bet even 14 would be fine.
