What car is it on and what kinda wattage is that gonna be pushing? I have no idea what wattage will be made when a person just says what their amp is...

Money. Lots of money.

Depends on your battery, alternator, and how much wattage you're planning on pulling.

Right now I just have a duralast gold upfront and my stock alt is getting rebuilt to do 170amps

And it is going into my 94 accord

And my f2500d is rated at 2500wrms underrated at 1ohm ut ill run it at 1.5ohm. And the 4channel is 60x4wrms

get a bigger front battery or a 2nd batt. that should keep voltage from dropping too much

Does your Accord even charge up to 14 volts? If it's anything like my 93 it'll max out at 13.8

I'm saying my alt is getting rebuilt to 170amps and ill run a trunk batt too

 

[Sarthos 10+ year member]

should be fine so long as you get a good trunk battery. Still if it's like mine the alternator simply won't reach 14 volts.

U think aslong as it stays in the high 13's it will be ok ?

Due to too big of a pulley mine hits 12 at idle and is okay. I don't push it too hard though thanks to the lack of bass in country music. I wouldn't recommend running an amp to the max if you do that though, but at high 13s it should be fine. If you can find how to get it to run at >14 volts though, tell me, my car has the same engine and alternator as yours, I'd like to get high voltage!

13.8V is just fine. A lot of systems run at that.
