wamba Posted August 31, 2020 Author Report Share Posted August 31, 2020 The more I read the more I think I'd be better off just running the one Mechman alt. I was just worried about the dependability of a alt that big being as it's my daily driver. Link to comment Share on other sites More sharing options...
1point21gigawatts Posted August 31, 2020 Report Share Posted August 31, 2020 If you aren’t gonna upgrade anything else then there’s no need in getting an alternator that generates more current. You would need to at least do a big 3 upgrade to generate that upgraded current. Because the factory wires only can support about 150 amps of current. Upgrading an alternator wouldn’t negatively affect your vehicle. Mechman makes a dependable alternator that has a lifetime warranty. Now when it comes to dual alternators, from what you have stated about wanting to keep things factory and stock tells me that you aren’t gonna be pulling enough current to need a dual alternator setup. What kind of car audio system do you have or planning on having? “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
wamba Posted September 1, 2020 Author Report Share Posted September 1, 2020 yea i've done the big three all 2/0 welding cable.

1point21gigawatts Posted September 2, 2020 Report Share Posted September 2, 2020 I thought you said you want to keep that vehicle’s electrical system stock? That’s far from stock. You confused me. Lol! But now I kinda understand what you mean, you wanted to keep you vehicle’s factory electrical system stock and dedicate the upgraded electrical system to your car audio setup. Don’t do that. You don’t need to do that. You need to double up on them 2/0 welding runs on that big 3 if you get that mechman 400 amp alternator to support that current draw. One 2/0 welding cable would not support 400 amps of current. You don’t need dual alternators. Just upgrade to that mechman alternator and that would be more than enough. Delete that front battery too. You’d be super happy. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...

Just double up 2/0 welding cables on the big 3 grounds and the lto bank ground. Can you explain the wiring under your hood to me and did you delete your front battery? “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
