  13. voltage drop after running the big 3

    ill have to check all my connections... i kinda doubt its bad crimps tho. all the wire that i used came out of my astro (which just died on me) but it didnt have any voltage issues. it was doing a 149.3 on music. i understand that i wont see a voltage gain and i also understand that the big 3 only allows more amperage to flow. what i cant figure out is why after running the big 3 ive lost almost half a volt.

    Did you clean your ground point down to metal ? Are you using 1/0 for the big three ? When was the last time your battery was topped off (is it brand new or used)?

    I may have been in error about the ohm readings. I may have had the meter on the wrong setting (at least the ones taken at the battery). However, why does connecting my amps make the measured voltage at the distro block drop? I just took another measurement and it was down to 12.27v but the battery is still at 14.17v. Opinions please?

    When you say connecting - do you mean its just plugged in or powered on playing music ?

    Also, did you mention earlier that you are grounded to the floorpan?? if yes relocate to a quality ground - do you have a picture of your Big 3 ground location ?
