helping 70a alt survive 2kw

[M@nJo 10+ year member]

My OEM alternator is rated at 70A. I have a dual purpose Optima yellow top under the hood, big-3 wires done with 4ga, and 2ga as my main power wire. My speaker amp is a Power Acoustik (100wx4) and my sub amp is most likely going to be Hifonics bxi1610d (1600w). What else is there to do to help keep my electrical system up to date? I was considering a Kinetik HC600 or maybe a cap to help avoid the dimming (which I know I'll get).

ps: I'm not going to be bumping my music loud everywhere I go and aftermarket alt is not an option this time:crap:

You won't see 2k with those amps. Hifonics is overrated and you'll be lucky to see 80%. Upgrade your big 3 to 1/0 wire.

I run a BXI2006d (gains set for 1600) and a front stage amp that does 300w off my stock 80 amp alt. Iv'e got big 3 in 1/0 and a small battery in the back (same as hc600). Do good off that.

That Kinetik is only 20 ah.

These are 18ah and I am sure are less then the Kinetik, I would get two of these if you can. I used to use 4 of these worked great.

alviate, dumple, and 7ender...how low does your voltage drop at idle and driving conditions (if you ever had the chance to measure)?

I drop to about 12.2 on the longgg bass notes, while driving. This is measured with a crappy in dash voltmeter though, never had a chance to check with my DMM.

While driving at night, I get very mild dimming.
