Alternator / System Voltage Question!

[Astyl 10+ year member]

Hey guys so i need to know some things really quick,

basically im really into car stereo, i have a 3800 watts continous RMS Amplifier, a EA 200 Amp HO Alternator, a Optima up front and a secondary battery in my trunk to help support the amp along with zero guage big three done

right now my alt charges a 14.6, and with my stock alt i got one of those ZZP Voltage Boosters that ups your voltage .6 volts, basically what it does is its a resistor that plugs into your alternators voltage reference line to trick the alternator into thinking system voltage is lower then it really is, so it ups the volts, i havent used it with my new alt yet, but using it with my new alt if everything works properly, would put my total system voltage around the 15.2 mark

im just wondering if running low / mid 15's for voltage is going to do anything bad to my vehicle? i know 16/17/18 volt setups are bad for daily drivers, but are low / mid 15 volts bad for daily drivers also or would that still be in a marginally safe area to run to all my system components ( PCM / Guage Clusters / ETC, basically everything )

i heard the stock wiring was rated for 17 volts max, but idk if thats true or not, and i wouldent be pushing anything near that, so do you think around 15.2 would still be in a safe zone to run w/o issues?

lots of car electronics can take 18 volt peaks and not fry. you definitely dont want it to be that high though for extended periods of time. its just a safey mechanism.

if you're idleing at 14.6, i wouldnt even put that little doo hicky in.

Most vehicles don't like anything over 14.7-8v.I would NOT recommend doing this.Just use the EA alt without the resistor and you will be fine.

I wouldnt do it. Id rather have a bit of dimming lights over a fried ECU.

ECU's are'nt cheap.If you have a newer car I wouldn't even try!
