Default low notes

currently i've got 1 run of positive, 2 runs of ground 1/0, stock front battery, 2 d3100's, a 220 HO alt, all running a saz3000d.

on high frequencies (40-50hz) my volts are perfectly fine, but when it comes to notes that are like 25-35hz my volts drop really low. if i let it play long enough, my amp will go into protect.

plannin on uprgading to at least a 300 amp HO alt, and possibly a d3400 for a front battery, and another run of positive. but then i'll be strappin another 3000d. so whats up with my electrical?

turn the gain down

low notes take more power to make power

add up your fuses then divide it by 2 and that is how big of a draw your amps have. then figure in how much power your car needs to run and boom, thats how big an alt you need

Is your box tuned low?
Lower impedance rise...

i feel like somthin isnt right there... i mean yes, it will draw more current on the lower notes. but you have two really nice g31 batts,and a HO alt, and you're dropping so low shit goes into protect? double check all ur connections and make sure you have good grounds

It could be maybe a dozen possibilities. So test. I personally doubt it is electrical.

Fallow the questions like rawlins on the tunning...

And heres a few more:
Got all of the Big 3 wires in correctly?
Did you wire the batts correctly?
Proper wire size to the subwoofer(s)?
Voltage drop across a battery?
Amp location?
Gain may be too high?

Are you doing .5 with the saz?

I forgot the more important ones i was thinking but i'm sure they will come up by others.

I forgot the more important ones i was thinking but i'm sure they will come up by others.

the box is tuned way too high, and isnt nearly big enough. i've got 4 12" american bass xfl's. went to a shop and they built my a box that is roughly 6 cubes before ANY displacement. a week from now i'm building my own box and gunna give each sub around 2 cubes after displacement.

1. big 3 is done with my added 0 gauge wire, and the stock ones left in there too.
2. batteries are connected, positive to positive to positive to amp positive. same with grounds, all the way back up to the front batteries.
3.the subs only have like 12 gauge, i got some 8 gauge that i'm going to install after i build the new box.
4. the voltage drop is only on the wire between the last battery and the input of the amp. the rest go no lower than 12.5v.
5. currently the amp is just sitting on the seat in front of the box? move it?
6. the gain is probably about 3/4 the way up, maybe a bit more. my subs could take it all, thats why i bought another saz. i use the bass nob, but it has been tuned properly by me, not the shop that built my box.s
7. its wired to 1 ohm, not half.

The small front battery could be holding you back, or you could have a bad connection somewhere. What brand alt?
