Voltage and ground issues

[zthumper 10+ year member]

Well I have my setup thats im my sig, so I am only running like 1000 watts max. I am only getting about 10 -10.5 volts at my stereo amp which is causing it to go into protect. Also i am getting horrible engine whining, i have checked my amp gound and it has no resistence what so ever. ALso I have a pioneer HU and i have heard that they are notorious for ground problems. I am going to reground my hu tomorrow and i was wondering do i just cut the existing ground and make a new one? Also for the voltage issue....i have done the big 3 what else should i do to get some more volts? Thanks

what does your voltage say at the battery?

what does your voltage say at the battery?

to ground your head unit just cut the ground wire right before it goes in to the harness and ground it behind the dash, might also want to ground your rca's too. are you using any distro blocks? if so i would check voltages there also

yes check voltages at different loacations, also make sur you have good gounds on all of your equipment

I think i know what the problem is.....i have kicker 4 gauge running to the distro where there is some crap walmart wire running to the amp. I am going to upgrade this and see if it helps. Where is the best place to get some distro blocks for cheap?
