What electrical upgrades do i need

[cris2216]

How many batts what size batts and size alt and how many runs of 0 ga do i need to power a aq3500 and stay above 14.4v its going in an 2003 chevy suburban

[hdorre]

What's the nominal impedance? Is it the 3500D or the 3500D.1? Is this the only amp?

[cris2216]

1.33 ohms and the amps are a aq3500d and a rockford t600.4

To stay above 14v on regular music(50% or less bass notes) you're gonna want one good alt and at least 2 group 31 batts.

If you wail on it constantly like you're trying to blow something up, you'll need a second alt.

im going to disagree on the second alt. unless its full tilt for the whole commute lol. i think the one 250amp alt and two g31's like you said should do just fine. 2 runs of 1/0awg.

i had two 1500's at .5ohm and an alpine pdx150.4 on my 270amp alt, g34 yellow top, and two G31's and i stayed above 13.5v if i remember correctly.

Why you gonna say you disagree with me then turn around and agree? Lol I say wail like you're trying to blow something, you say full tilt for the whole commute. Same concept really.

I agree, no need for dual alts. But a single Mechman 270 charging a nice starter battery, and an XS Power D3100 with 2 runs is more than enough.

I could make 2 group 31s and a group 34 on a DC power 270sp drop to 13's with 2 aq2200s at 2 ohms strapped. He'll need more then you're suggesting. All brand names aside.

[cris2216]

So which should i go with dc or mechman

And batteries go with 1 or 2 xs d3100's

And a mla module

Should this keep me at 14v

[Sanitarium]

Either alt, I prefer DC.

2 group 31 batteries, XS or deka 9a31, they're the same thing, and consult the alternator manufacturer about voltage modules.
