EricM9104 Posted January 21, 2008 Report Share Posted January 21, 2008 help.... plz. ok, well today I got around to checking my friends voltage at full tilt with his lights on (truck on, idling) and his voltage drops from 14.6v (radio not playing) to 11.91v (full tilt). Single amp, Audiovox Rampage 500w amp.... 30a fuse, 10ga amp wiring.... Just trying to figure out the stock alt size. Also, would upgrading the amp wiring to say 4ga help with the voltage drop? (i measured the voltage at the amp....) Should I check the voltage at the battery? 2015 Honda Civic LX 4dr | 24k miles Stock H/U and mids/highs Power Acoustik GW3-12" D2 Sub HiFonics BXX1200.1D @ 1ohm Random 2.5^3' dual ported box NVX LOC Stinger wiring throughout 1977 Chevy SWB Cammed 350 Dual exhaust Cheap Wish stereo Link to comment Share on other sites More sharing options...
