JeepAndBassXJ Posted October 26, 2013 Report Share Posted October 26, 2013 So I have been trouble shooting reasons my amp shuts off on some songs and I have been looking at everything wondering why I keeps going off. I started looking at my voltage and have stumbled on a voltage "loss" between the battery/alternator and the amplifiers so this might be my problem with the amp. My electrical: All wire is KnuKonceptz KCA Kable -200 amp high output alternator with a 14.5 volt set point. -1/0 gauge to the battery with 200 amp inline fuse holder (1ft.). -Duralast Gold 780 cold cranking amps battery. -1/0 gauge with 200 amp inline fuse holder to the rear of the car (12ft.). -Distribution block (1/0 gauge to 4 gauge) with 150 amp fuse. -4 gauge to amp (1.5ft.). -(3) 1/0 gauge ground runs from the battery to chassis, engine block, and alternator (All about 2-3ft.). -1/0 gauge ground to distribution block (1/0 gauge to 4 gauge) -4 gauge to amp (1.5ft.) *The voltage at the alternator and battery was identical no matter the circumstance so that connection is fine. * I have triple checked all my connections including grounds, fuses, and at the amp. I played a 60Hz tone all the way up at idle and the voltage at the battery/alt was 13.95, at the amp it was 12.65. I have loss somehow but I have no idea how of were it could be. I want to get a kinetic HC 600 battery with high quality fuse holders to put next to the amp but will this fix the voltage loss? Any information would be great!!

RMac18 Posted October 26, 2013 Report Share Posted October 26, 2013 You could try checking the voltage before and after any fuse holders, distro blocks, ect and see if maybe your losing it through a fuse or bad connect or something. Link to comment Share on other sites More sharing options...

skittlesRgood Posted October 26, 2013 Report Share Posted October 26, 2013 connections could still be bad, although you think they are good. could be cheap fuse holders or distribution blocks. if the amp grounded to the battery or the chassis? if chassis, where? this is definitely a connection problem. taking pictures of your connections will REALLY help us to help you. What amp do you have? If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.

revoracing247 Posted October 26, 2013 Report Share Posted October 26, 2013 how much power are you running? ie what amp is it? and 12ft of kca and then to 4ga could be your problem if you're trying to run like 2K+ rms. but i know theres people way better at actually calculating the current numbers and stuff in your car I think you have a bit of truck stuck in your mud bro ~Ford Ranger, ext cabKenwood DDX4701/0ga stinger wiring for big 31/0ga ofc flextech wiring 3 kinetik 800's AQ2200 @1ohm Sundown Audio X15 in a 27Hz tuned ported box LE BUILD LOG!!!

Quiet Posted October 26, 2013 Report Share Posted October 26, 2013 What amp? 2007 Pacifica Rebuild. Less quiet. Still not loud. Link to comment Share on other sites More sharing options...
Soccerballzs Posted October 26, 2013 Report Share Posted October 26, 2013 Could have faulty fuse. Bad soldered connection in fuse. Try another fuse. May not be able to see bad fuse. http://www.stevemeadedesigns.com/board/garage/vehicle/2438-jeep-commander/I Pioneer P99RSAmpere 38002-Ampere 125/44-6.5 inch Hertz HSK XL Mids4-8 inch JL Audio ZR Midwoofer 2-5.25 Satori Mids2-Morel Tweeters, 2 Hertz Milles 3 inch on A pillars2-Hertz Silk tweeters DC Audio Level 5/12 Skyhigh Wire Mechman 320 XS Power D3100MO Funniest Thread of the Year 2013: http://www.stevemead...dy-being-a-pos/ Link to comment Share on other sites More sharing options...
JeepAndBassXJ Posted October 26, 2013 Author Report Share Posted October 26, 2013 So I changed the ground so that it bypasses the ground distribution block and now the voltage only goes down to 13 so that's improvement. So I'm guessing it's just the distribution blocks?
