Hi my fellow audio fanatics, im about to build a competition car ill be useing 3 altenators 1 for my car electronics and 2 for my system I know that ill need a bracket fory additional alts. My ? Is how does the two alts wire up and what other componets will I need. I have been doing car audio for 22 years bit never competed any detailed feedback will ne greatly appreciated.

 

You don't need three alternators. Use one good one and an appropriate number of batteries.

 

That what im going to do, I just sold my lanzar optidrive amp and i have been looking into cadence amps I do fiberglass and im workng on my demo car. I saw a 16v alternator 300amps and cadence can handle that easily and I found some really good batteries for a reasonable price.

 

Db drag or idbl ? Class?
Depends on what class you would like to fit best in.
I have run alot of power on a single battery and alt.
In competition, you want as much voltage for 5 seconds.
An adjustable regulator with a 200 amp alt and 1 or 2 group 31 batteries
will supply 20,000 watts with ease.
BTW agm Batts like 14.9 volts.
16v will shutdown many pcm
I have used 15.5v in outlaw. Rules will state voltage limits.
Alt for 16v system charge at 18v.....
