The battery and alternator are the source points, and have the lowest impedances in the system. The closer you get to the battery, the lower the noise. Those "accessories" ground to the body (like your amp), and ultimately return to the source - the battery.No. Battery goes to engine block (and therefore starter) through a large wire. Alternator negative is also to the engine block through its case. Engine and drive train are isolated from the frame on rubber mounts. Body is also suspended on rubber mounts. The electrical connection from battery/alternator negative is through braided ground straps to the firewall and from battery to a body ground point - usually the fender. That's one of the "magic 3" people upgrade.Perhaps you should try being a bit less condescending and maybe learn something yourself.</blockquote>
