You think it could be bad ign contact? Or something else?
Yes, that would be possible.
Did you have a noise filter installed on power wire to the stereo system?
If not, that may have been the cause of the flutter or it could have just been from the sound wave presssure from the subs.
The voltage gauge flutter would lead me to suspect an intermittant contact that may or may not be the ignition switch.
I would also check your grounds, specifically at the engine and ECU.
