It will have a HUGE(and bad) effect on the amp's performance. Try running a mile while holding your breath - then you'll understand what the amp is going through with a poor ground.
Typically a poor ground, or some how the red wire is touching the black
amp by pass harness
If the amp is in the trunk.Just ground it to any part of the metal body.
your amp will ground in your sound system, or through your power adder which rock.
The main parameter responsible for virtual ground of an Op-Amp is Input Impedance . Generally , for an Op-Amp it is very high . So , we can conclude that the characteristics of an Op-Amp responsible for virtual ground is high input impedance .
The amp will lead a dull and empty life.
i would check you have a good ground the amp will still power up but no power will be put through the system if the ground is not good
An op amp must remain in its active region for virtual ground to be preserved.
either your amp has a short..... or.... you have a bad ground
Positive post of capacitor is connected to the heavy amp cable. The ground terminal (or case) of the capacitor is connected to the car's ground or a ground wire that leads to the car's chassis. That's it.
Since the resulting short circuit would be outside the amp, it WOULD NOT blow the amp.
Ground zero should be able to advise you on a power amp and sub.
