new guy Posted April 4, 2012 Report Share Posted April 4, 2012 (edited) i have a 1996 ford mustang v6. i have a brz-1700 and 2 skar 12s. my car will idle at 14.8 no matter what according to my volt meter. all the way up to about 70% volume i have no voltage drop what so ever not even by .1 volts but when i get to about 75 - 85% i drop down to high 13s but the whole car acts like its about to die. my rpms start dropping car shakes all my lights dim like crazy. i dont under stand why i have a what i believe is a entirely stock electrical. why does it act so weird?

Robby Holmes Posted April 4, 2012 Report Share Posted April 4, 2012 cause its stock electrical. it may idle at 14.8V, but because of the small wiring, your alternator can't push in enough power to keep it at 14.8. i could possibly be wrong, but thats what it seems to me Quote '08 Chevy Cobalt coupe 2.2 base model trunk build: 2 9512iSC flatwound alum 1.5 coils -extra 9500 spider pack -8" platinum carbon dustcaps 1 DD Z1 (.375ohm nominally daily) 3g31 AGM 320a Ohio Gen alt 1 DD S4 4 channel 4 VO-M8v1's (holes cut for 3rd pair) 2 CS 6.5's 2 VO-B1's Sony XAV-601BT all Knu Krystal RCA's Cadence 7band EQ ______________________ 148.3db @ 32hz (burp) 148.4 @ 37 & 38hz (burp) 146.xdb 90sec average (center windshield) Link to comment Share on other sites More sharing options...
new guy Posted April 4, 2012 Author Report Share Posted April 4, 2012 (edited) yea i know that but what i dont get is the amp is putting out atleast 800 - 1000 rms without any kind of voltage drop but as soon as i get around 1200 rms my car starts just going crazy but i never go below like 13v i know my stock electrical cant support the full 1700 rms Edited April 4, 2012 by new guy Quote *current* 1991 honda crx si 2 skar audio 12s pioneer 6.5s dual 400 watt amp audio technix db 1/0 wiring kit. dual head unit Link to comment Share on other sites More sharing options...
matt14 Posted April 4, 2012 Report Share Posted April 4, 2012 What voltmeter are you using and where do you have it hooked up too? Check the voltage at the amp with DMM and see what the differance is when its reading the 14.8v Quote 2006 GMC YukonPioneer HU SHCA ran throughout Crescendo BC3500 One 18 AA Mayhem in a 4th order ZED Levithian 6 channel Rainbow Dual 6.5 comps ran Activehttp://www.stevemeadedesigns.com/board/topic/155628-matt14s-yukon-mayhem-in-a-4th-ordernew-amps-and-bats/page-3 Link to comment Share on other sites More sharing options...
TylerParrish Posted April 4, 2012 Report Share Posted April 4, 2012 you'll never see the full 1700 with that amp anyways. Its rated at 14.4 volts, which means you'll need to constantly be charging and staying at 14.4 volts to sustain that 1700 watts, and even then you won't see it cause amps aren't 100% efficient.

new guy Posted April 4, 2012 Author Report Share Posted April 4, 2012 i have a scorpion voltmeter i think and i tried straight to the batt and i tried to the radio. ill try to get a dmm and check. ill try to hook it up to my amp and see what it reads. maybe mustangs just have some kinda regulator or something to make them read incorrect.

D-train-13k Posted April 4, 2012 Report Share Posted April 4, 2012 im pretty sure that most all fords have a pcm controlled alt. so unless your bypassing that your not going to use the full power of your alternator. even then on a stock electrical your alt probly does maybe 100 amps. your cars probly using 30 amps to run.. so 70 amps left for everything eles. there goes your 700 watts.
