Alternator upgrade question

[ta2ed9783]

Will it be a noticeable difference or be worth it to upgrade from a factory 90a alt to a reman 130a alt? I am running a Sundown saz1500d v2 and a Fosgate p4004. Pioneer 4 volt preouts. Big 3 and power/ground runs in 1/0 ofc. I can get a good deal on the 130a and I am on a budget so I just wanna know if it will be helpful with voltage drop. I plan to also upgrade to a big agm battery and another in the back.

A 130 prolly not a 150-175 yes

what about the extra batt? I was plannin on kinetic up front and thinkin about a big eaton or powerware in the back. Will those ups batts work fine for extra voltage?

The batts will help. But may not be enough

If your planning on adding more batteries i would suggest you get at least that 130 amp alternator, the stock 80 amp one will be working kinda hard keeping 2 batteries charged up.

I think you would notice some difference with the 130 amp alternator if its built properly and not overrated, it does have 40 amps more charging capacity.

Back in the day i seen my friends stock 100 amp alternator get so hot it was glowing red at night. He had it charging 6 hawker batteries.

How bad is your voltage drop currently?

with volume as loud as im willing to take it, I might drop to 12.9 or even 12.7on a heavy bass note with the two amps in together. I just got my new dmm so im gonna set the gains properly today and see if that helps. I jus have em set by ear right now

Do you think jus adding a 50 or 60ah powerware batt in the back would keep it over 13 volts? An i'm only running a 2.67 ohm load on the saz1500d right now. So I imagine if I run a1 ohm or lower load it would drop even more right? I definately dont want to damage these amps. I had to save up to buy them.
