The word on the street is, you want 160+ amps on an ALT.

Dude nothing will fry if you upgrade your alt its a myth.

Just get a new alt and get one before you even connect up the amp.

160+ is a good idea.

160amp alternator is the smallest you should use,get a 200 to 250amp alt for headroom incase you decide to upgrade later on or add some amps for components.

2000w should have a current draw of 138amps max and a 160amp alt would do fine but if you add some component speakers and amps dedicatd to those then depending on power you would want a 200+amp alternator.

I am going to need a 250+amp alt when I do my new system and a good cranking battery under the hood and some HC2000's in the back dedicated to the system itself.

how about just a high output alt with big 3 but no extra batt?

is the herc the 2000rms one?

the goliath reccommends 500a fusing, i would guess 200-250a fusing on yours, but it wont pull that much

would it be ok with a 240 amp alt?

dude its a hercules, its not the maxximus, you guys are making it sound like this dude needs his own power plant in his car.. its only a hercules, its nothing special

You could get away with doing the big 3 in zero guage, and a yellowtop under the hood and call it a day

160 amp alternator and Big 3 done in 1/0 gauge.

To do 2000w would take up 140 amps about and most alternators I believe have a 40% reserve but I am not sure about H.O. alts.

but for the heck of it 160 + 40 reserve = 224amps (at the proper RPM I would assume)

224 - 140 = 84 amps left over for the cars electrical and some component speakers amps.

so a 240 amp alty and a yellow top and i'll be straight right? i dont wanna fry a $500 amplifier.

No matter how big your alt is you won't fry your amp unless it is regulated to charge with anything more than 14.4v.

160 amp alt to a 200 amp alt and you're set bro...

Before you spend the money on a alt install everything,if you get diming then get a bigger alt.
