I have a 120 amp alternator and a 10 farad cap in a 2001 Jetta. I get alot
of clipping at higher volumes from the subs. The voltage drops to 12.5 or so
but the two PG tatnrum 1200.1 amps need to see 14.4 to produce full power.
They are driving two JL 13w7s sealed.

Will another battery, or replacing my existing battery help with my systems
clean output? And if so how?

then what is it? it's at a high volume but no where near the drivers'
limits.

If you "get a lot of clipping", then the supply voltage is NOT the
culprit.

What size wire is feeding the amps? at maximum output, they will pull a bit
more than what the alternator can supply. Possibly around 175 - 200 amps.

1/0 to capacitor/distribution block then 4 guage to the two amps.

bottom line is alternator change is not doeable in ontario with this car. i
wanna know what my other options are.

Well, what are you hearing? And have you tried a scope on the outputs (not
everyone has access, I realize)?

low level mechanical sounds at the transients sometimes sharp and louder.
the thing is i can play alot louder overall if i set the crossover to 50hz
with a 12 db slop than i can at 80hz. i know its the amps. but don't know
what exactly to do. i know what i'm desscribing sounds like bottoming out
but i assure you its not.

You could be clipping then, but fixing the supply voltage won't help you
much. The difference in power is not significant enough.

they need 14.4 volts to get their max 1500 watt ouput anywhere from 2-4 ohms
(according to pg support) but i also thought that a drop to 11.5 volts
wouldn't be that bad so they shouldn't clip like they do. i KNOW i have the
gain set correctly.

so you think that only an increase in amperage will fix this problem?

It's odd. But I don't think you can suspect clipping unless you look at it
on a scope.

I do?
