I agree it's a poor system, in fact I regret ever doing what I've done knowing what I know now. Your response does nothing to benefit the resolution of the issue. I have pulleys coming to make them equal. You seem to be intelligent with electrical and wanted to know if you thought two...

No, I added the second alternator. It's wired exactly the same as I described above but both have completely separate circuitry. The alternators dying is not new since the dual alt set-up. Everything occurred after the "professional" audio installation. I don't know why in gods name the audio...

The circuits are about as easy as it comes. One terminal on alt is hot at all times. The exciter circuit has 12v applied to the circuit when cranking or ignition on, it then goes through a 470 ohm resistor that is paralleled with the charge indicator light and straight to the regulator. So...

Thanks for the reply. I completely agree with you. despite returning the red tops, I have no idea what to use now. I think agm batteries do not agree with my truck/system. it has been a battle that Im over, Im considering just going back to a regular old lead batteries. I also agree about the...

Yeah man, it's been rough, especially dealing with it & having a newborn at home. Which single do you have & which would you recommend for me? What batteries are you running? Like I said, my system pulls 70 amps by itself on top of all the factory stuff. I know my glow plugs pull 60-65...

Thanks for the reply. I did a bunch or testing this morning. I nabbed the carbon pile tEster from work and did some playing. What I found is the optimas do not like taking a charge. They are super slow to recover now. My upper alternator is putting out 100 amps at idle and 160 at 1500 rpm. While...

I have already ordered (2) 2.30" pulleys. Factory is 2.5. That should raise it my sweet spot and only raise rpms 1000 at redline. They should be here Tuesday or Wed at the latest. Batteries have been tested and retested. While the alternators were at the shop I brought them to work & used...

I ALSO HAVE A CORRECTION, THESE ARE BOTH 6G ALTERNATORS. sorry for the incorrect info.

Yes, when I come to a stop after pushing the system, I turn the music down and voltage drops to ~13.2. Raise the rpms a few hundred and immediately hits 14.2v. Always is rocks solid while driving at 14.2v with the system working hard. Even massive bass hits do not affect while driving off idle...

Thanks you guy again for the replies!! Rectifier is failing, I'm starting to realize auto electric shops know how to disassemble, test, rebuild but not really what is going on & how it all works. These are small 3g cases. The auto electric shop said the rectifiers were cheap & small...

Another note, the alt shop did not change pulley diameter. I'm considering going from a 2.5" to a 2.25 " which should eliminate my lower voltage at idle after stopping and charge better below 1000rpm. I calculated it and it would only increase alternator speed at redline by 1000 rpm, maxing it...

First off, thank you all so much for the replies, I really appreciate it! I'm getting sick of working on this more than enjoying it after dumping all this money into it. I DID NOT have any of these issues prior to the stereo installation. Big 3 is not done per say. The factory cables have been...

Yes, they are still using stock internal regulators. Aren't the regulators just for voltage output regulation? My voltage appears to be okay while driving. The regulator is definitely taking longer after start up to get to the 14v range. Tap the throttle and immediately it's at 14.2. My system...

So, I have a Ford f-250 with a 7.3 diesel. I'm running 2 high output rewound alternators (160 amps each) 2 brand new red tops, I have made 2/0 battery cables for everything. My system includes a rockfprd t-1000-BD pushing 2×12" Rockford subs (unsure of models, t-600-4 (unsure of door speakers)...
