Hi! in the last few days I hear more and more scary stories about noises because the mass cable goes back to the battery and that one should UNBEINGT take the shortest away to the mass (car body mass punt). so, now I come: as an incoming e-technology student I think to myself the following… -The circuit of plus cable – amplifier – mass cable is basically a row circuit of 3 resistors. -In the row circuit the voltages add to the total voltage. – I want v ie voltage at the amplifier – thus as low as possible resistance in the cables. – (now comes) when I direct the mass directly with the thick copper cable back to the battery the resistance is much smaller than when I first go over the blech car (conductor value!) and over several clamp-niet-foam connections and finally via the mass cable in the engine compartment back to the minuspole. So; money and expenditure are not important for me. I want a clean circuit without noise and Lei What now, mass point or directly back to battery mass? Maybe which answers can the mass have led back to battery minus and what experiences they have made. THANK YOU!
