Tahoe Dmo Posted December 22, 2016 Report Share Posted December 22, 2016 I'm trying to make my electrical even more solid. I've got a hell of a power hungry amp (T2500-1bdcp). As of now I've got a Mechman 270 amp alternator and an XS Power D3400 under the hood. Would it be better to do dual alternators or should I get a few D3100s? Thanks, guys!

Kyblack76 Posted December 22, 2016 Report Share Posted December 22, 2016 I ran a BDCP at .5, with a singer 225 alt, yellowtop up front and d3100 in the rear. If i saw low 12's, it was almost never.

ShadeTreeMechanic Posted December 22, 2016 Report Share Posted December 22, 2016 A battery in the back will help it a lot more than another alt at this point. The battery can give power to the amp faster than the regulator inside the alt can switch on. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...
Kyblack76 Posted December 22, 2016 Report Share Posted December 22, 2016 And I had a rf 1000.4ad in there. At 4ohm though. Let me guess. That low voltage is at idle??? Rev it dude. I would just add more reserve. If you can do Duals easy. Then do. But I bet you can't. What car , and all that.

Tahoe Dmo Posted December 22, 2016 Author Report Share Posted December 22, 2016 No actually the low voltage isn't at idle. Of course it depends on the song too, but I don't ever like to see low voltage. And yes, I can do dual alternators easily. All I'd have to do is get a dual alternator bracket, which are easily found for my vehicle (02 Tahoe 5.3), I've got two other alternators at the house. But I didn't know if a battery or two in the back would be better than running a second alternator. Link to comment Share on other sites More sharing options...

DLHgn Posted December 22, 2016 Report Share Posted December 22, 2016 I mean, if you have another HO alt sitting around at the house, you might as well use it. Link to comment Share on other sites More sharing options...
