i'm currently running a 2k system on a 105 amp alt, lots of copper, 2 batteries(northstar NSB75's), IXL 12's @1k each, visionik V900hc. anyway the specs are in my sig line.

as far as power supply is concerned without any mods the best i can seem to get is about 170amp for $300 to rebuild my alternator.

would that be enough to run 3k-4k?

and i've been drinking

thanks.

You are fine IMO.

You will need a high output alternator and another nsb75.

He said he's getting the H.O. Alternator ... and the NSB75 is a big battery to begin with ... 3k, so he needs 1 of those batteries PER 1,000 watts, that's what you're suggesting?

You always want to have as much power on tap that you can get ... there is no such thing as overkill ... maybe that's what gramser is suggesting ...

Gotta pay to play

3k would be fine but he mentioned 4k, I am daily driving 4k with a 270amp alternator and 150ah worth of batteries and dip 12.7-13 volts when I'm hammering it.

If you go that route watch your voltage when going full tilt and check your resting voltage in the morning before you start the car.

thanks for all the replies guys, i installed a volt meter and when i hit higher notes it will drop to 12.5 or so as well, so i generally only listen to dubstep with lower end bass.

the other thing i was thinking of was to put in a third 12" sub and run the amp at 1 ohm for 3200watts. and then i would get the upgrade on my alternator.

but for now it will work i guess, i really should work on sound quality though.

mechman makes a nice affordable alt , you can also add more runs of wire , , if you havnt done the big 3 thats also a very simple and easy mod

thanks for the tip on mechman, i sent an email to them.

as for copper, i have enough, 2/0 from the alt to the bat, then 4x 4AWG positive and same for negative. then 2/0 from the rear bat to the amp.

several 4AWG body to battery to engine block, etc.

sounds like you have a pretty good electrical system , a mechman alt would be a excellent edition to your charging system , adding more batterys , or even a cap would be huge as well
