E-Train Posted July 2, 2008 Report Share Posted July 2, 2008 (edited) Mine did that, and the RCA outputs on the back of the radio had gone bad, and then it did it again and it was just where the RCA's had gotten pinched and naked wire was touching metal so try getting new RCA's first and if thats not it have your local audio shop look at your radio Edited July 2, 2008 by e_train Quote 1997 4 Runner Alpine CDA-9886 4 Fi Audio X Series 12's 1 Crunch GP3000D Pro DC Power Inc.

flashlight_65 Posted July 3, 2008 Author Report Share Posted July 3, 2008 i took it in and the guy at the shop asked why am i going to run a seperate battery if my alt puts out 300 amps. i told him about the set up and he never heard of FI audio which is ok but he said if i hook up my deka im gonna get more noise. he also said the alt or alt connection could be the source of the noise. i dunno, i didnt want to sit and argue so i left even more confused Quote My builds: my caddy my 'hoe friends impala Link to comment Share on other sites More sharing options...

missinglink Posted July 3, 2008 Report Share Posted July 3, 2008 it only started making the noise when i installed my new alt. i'm not blaming the iraggi. do you think a mla module will help? Our module will not do anything for that kind of noise. We do use ferrite inductors to reduce the switching noise feedback from the internal regulator. The ferrite damps the 400hz switching noise, as well as other resonant noise. Many newer alternators are equipped with avalance diodes which help clamp noise spikes. Some alternators also contain a capacitor to deal with noise. Without knowing what vehicle & alternator type you are running, it is difficult to guess the actual source. You say this started when you installed the alternator - what else was done when you did the job? Did you R&R a plug wire for access? You mention the "big 3". Do you have a ground wire making good contact with the actual aluminum alternator case, running straight to the battery negative? 'Link Quote missinglinkaudio The United States Marine Corps.

'Link the conections for the grounds are the mount of the alt to the frame and - of the battery to the body sheetmetal. the vehicle is a 1993 cadillac fleetwood brougham with a 5.7l v8 and the a 300 amp iraggi dominator. R&R a plug wire? i dont know what that means Quote My builds: my caddy my 'hoe friends impala Link to comment Share on other sites More sharing options...
