What I learned by searching different sites is that in case of a floating ground the speaker outputs are separated from the ground of the casing/chassis. The resistance will be high. When you have a common ground system all the grounds are the same and the resistance will be very very low. There are a few things that I would like to understand. 1.

floating ground on ICs? - High-End Audio Discussion Forum

https://forum.audiogon.com/discussions/floating-ground-on-ics

01-08-2007 9:20am. Edit. Delete. some have suggested a floating ground is a good idea - ie, connect the outershield to one end only, float the other. That is not floating the shield! It is MANDATORY that you do so with single-ended cables, because connectong the shield to the RCA ground on both ends just creates a low-resistance bypass for the ...

Bose/Audi designed the system to use a single common between the head unit line out and the Bose amplifier line input, so it is four wires (FR+, FL+, RR+, RL+, Common) with the common not tied to ground, it is a floating common. However, new car audio electronics use a common that is tied to ground, with both the head unit and external ...

For a standard push-pull output, connect pin 2 to unbalanced input, pin 1 to input ground and leave pin 3 floating, do not attach it to ground (with a standard push-pull output it may cause overheating of the drive IC)

The floating ground adapter is required because your car has an amp that is part of the premium sound package. It is located at the top center of the dash in a 5x8 cutout. The stock radio has a low power (3 Watt) amp that drives the higher power bridged (12 Watt) amp.

8 Power Supply Earth/ Ground. Power supplies are usually earthed to the chassis, but in some cases the DC side may be left floating, or grounded using a loop breaker (see next section). The important part is exactly where you choose to join the supply zero volt (earth/ ground) point to the chassis. With any power supply, the transformer's ...

MYTH: Audio Inputs and Outputs Should Be “Impedance Matched” Wastes half the signal voltage and places an unnecessarily heavy load on the driver! Transfers maximum power in vintage passive 600 Ωsystems but not applicable to modern audio systems driven by signal voltage Higher frequency cables are terminated with the “characteristic impedance” of the cable to

completely isolated from ground. A floating circuit can have safety issues associated with it due to the fact that there is no low impedance path to ground. However, this type of circuit can also help isolate a system from interference problems caused by ground loops.
