yota_oddball Posted July 20, 2009 Report Share Posted July 20, 2009 (edited) So I have a Nissan Armada with stock alt with a xs power d5100r battery as my main supply. I have a sundown audio sae 1200 amp powering a 15 fi bl. Im running 4 gauge wire. The gain is a little over half way up. Now this is where my problem is. When I turn the bass up my voltage drops tremendously fast and then the amp shuts off or at least the sub cuts out for about 5seconds. While this is going on the protection light blinks when bass hits (not real bright). My lights, when on, almost go completely out. Im fixing to do the big 3 with 1/0 wire but I just don't believe thats going to fix my problem. My last setup before was a RFt1 10 and an Alpine type R with a RF t3002 amp rated at 250x2. This setup actually almost out beats the Fi with 1200 rms with very little light dimming. Any ideas what could be my problem? Also the car is cranked while this is happening.

93TurboDsm Posted July 20, 2009 Report Share Posted July 20, 2009 you probably should look into getting a bigger alt maybe even an extra battery not sure on that one if your lights go basically all the way out lol Quote (1) RE MT 18" (2) Orions D5000s (1) Fiamm 500 flx 12 agm batt Link to comment Share on other sites More sharing options...
Guest Posted July 20, 2009 Report Share Posted July 20, 2009 you probably should look into getting a bigger altmaybe even an extra battery not sure on that one if your lights go basically all the way out lol if his voltage is THAT bad, i'd say that they're dropping into the high 9's to low 10's if the amp shuts off AND the lights shut off. a high output alternator would help tremendously.

93TurboDsm Posted July 20, 2009 Report Share Posted July 20, 2009 yeah lol cause towards the end he says his lights almost go completely out so thats pretty bad voltage drop Quote (1) RE MT 18" (2) Orions D5000s (1) Fiamm 500 flx 12 agm batt Link to comment Share on other sites More sharing options...

Blazerbass Posted July 20, 2009 Report Share Posted July 20, 2009 maybe check how many amps is coming out of the alt. depending on the year of the car it might be shot or is starting to burn up. or maybe another battery Quote http://www.secondskinaudio.com/ Link to comment Share on other sites More sharing options...
Guest Posted July 20, 2009 Report Share Posted July 20, 2009 maybe check how many amps is coming out of the alt. depending on the year of the car it might be shot or is starting to burn up. or maybe another battery yea, a diode couldve blown out in the alternator causing it not to output as much power as it can. So how do all these people run over 1500watts with stock alt. with not nearly as much drop that I am getting? Yeah HO alternator for the armada is $500. That sucks different companies have difference price listings. look around to Iraggi, DC alts, Excessive Amperage. and a few more i cant remember Quote Link to comment Share on other sites More sharing options...
93TurboDsm Posted July 20, 2009 Report Share Posted July 20, 2009 yeah ide check the amps coming out of your alts yourself first and go from there Quote (1) RE MT 18" (2) Orions D5000s (1) Fiamm 500 flx 12 agm batt Link to comment Share on other sites More sharing options...
