either your amp has a short..... or.... you have a bad ground
Either due to a bad ground or a bad amp.
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.
amp by pass harness
From my experience amp is bad cuz when i drank it i got diearea
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 .
for a fist amp its not bad but dont screw your subs over if you have good subs and a bad amp. go with hifonics or somthing good if willing to spend,
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.
