kickass audio Posted July 27, 2011 Report Share Posted July 27, 2011 Have you checked the resistance of ALL your power and ground wires? If there is no load but there is a ton of resistance in the line, the voltage will be normal but if you load the wire down and there is resistance, it will drop voltage since you are basically squeezing the power. Since i have had this happen to me so many times, i always run my wires and take my TPI 440 and test resistance (but a normal DMM works as well) any run that is greater than .2 ohms in resistance needs to be redone. I always run it so that the positive of the wire coming from my alt, i test it to the positive of my battery. When checking resistance make sure you NEVER cross a positive lead to a negative lead. If you do this you will fry your meter and possibly melt the probe wires.

bmph8er Posted July 27, 2011 Author Report Share Posted July 27, 2011 i also forgot to put when i first put the new run of 0 in it worked fine for prolly a week. it just started all the sudden today out of no where. ive been doin audio for over 10 years this is the first time this has happened also first sony amp i ran. i should jst burn the amp i think its my honda rejecting the pos amp Quote 2001 gmc seirra 5.3 auto 3.73 locked rear, long tube headers, offroad y pipe, duals, cai, black bear tune, 2/4 drop, 22s, rockford fosgate mods and highs and 4 ab hd 15s and a ab 750.1 1995 civic 1.5 auto slower then hell, dropped on coil overs, ex hub caps, 2 12 trunk, have 450 bucks in the car and gets 35 mpg 1992 s10 being bagged, shaved, and small stereo. right now a pile of parts Link to comment Share on other sites More sharing options...
bmph8er Posted July 27, 2011 Author Report Share Posted July 27, 2011 any other ideas postem up ima work on it again tonight till it is fixed Quote 2001 gmc seirra 5.3 auto 3.73 locked rear, long tube headers, offroad y pipe, duals, cai, black bear tune, 2/4 drop, 22s, rockford fosgate mods and highs and 4 ab hd 15s and a ab 750.1 1995 civic 1.5 auto slower then hell, dropped on coil overs, ex hub caps, 2 12 trunk, have 450 bucks in the car and gets 35 mpg 1992 s10 being bagged, shaved, and small stereo. right now a pile of parts Link to comment Share on other sites More sharing options...
dohckiller808 Posted July 27, 2011 Report Share Posted July 27, 2011 I would test that resistance first. If not that then swap the amp. Quote Link to comment Share on other sites More sharing options...
kickass audio Posted July 28, 2011 Report Share Posted July 28, 2011 I thought of something else but im sure you are more than smart enough to not do this but ill chime in anyway. Are your wire ends stripped back enough so that the screw comes down on the bare wire and not any insulation? I fixed my friends truck and the jackass shop he went to put the wire in the distro without cutting enough of the wires jacket off. Other than that i really dont know what else could cause a problem other than that resistance in your wires. Just start there and work from there, report back when you complete it so i can help you from there.

Blackedout Posted July 28, 2011 Report Share Posted July 28, 2011 Gonna go out on a limb and say it is a bad battery or a resistance problem. Reason I think so is because a short that would pull a battery from 12.8 (floating) to 6 volts would have started a fire before you had the time to measure 6 volts. So, I rule out the amp too.

dohckiller808 Posted July 30, 2011 Report Share Posted July 30, 2011 So what was the verdict? Quote Link to comment Share on other sites More sharing options...
