Voltage dropping to high 10 - mid 11?

[dylan117]

Ok so, I have a 2000 S10 blazer, it still has stock alt that is 90-100 amps. I will be doing the big 3 in the next day or two, but I have an average duralast batery under the hood (it's kinda old) and an XS power D4700 in the back. As for an amp I have 1 AQ2200 running at .7 ohms. As for wiring I have all Skyhigh 1/0 OFC. I don't quite understand why my voltage is struggling so bad, will the big 3 help enough to make a difference in my case? Thanks for the input. Also is an XS power d4700 considered a big battery? Thanks

Wired below 1, electrical not up to par, that's why...

Get a bigger alt and use the XS as the main...

I really doubt the big 3 will bring your volts up. It could be your gain is set to high. And your alt isn't putting out enough amps. you are running your amp at .7 ohms you say...remember that.

charge your batts also since your alt is not enuff to keep them charged at all your voltage drop will just get worse and worse till something gives

charging the battery wont help much.. 1 minute playing will drain it again.. get a bigger alternator and replace the front battery with agm
