[QUOTE="DRBOOM, post: 8670593, member: 676005"] Oh, that reading from the ground terminal is does not sound correct. You need to educate yourself on how to use a multimeter. Its your best friend in car audio issues. This is how you use your multimeter to see if you are getting a good reading with 12 v. Set your multimeter to 12v dc, not AC. probe the red one on the battery positive on your amplifier, and the black one on your negative one. Should read 12v. Ask a mate to start your car and keep the probes there to see the voltage drop. If it drops to a few volts then you have to check your grounding points on the amp, head unit and test it again. If the voltage still drops to a few volts then its time you replaced your battery. Hope this helps you out mate. [/QUOTE]
