Big 3 Upgrade: Planning Stage (Input Encouraged)

[The Architect]

10KW is a litttttle bit rough.

figure the car will use 25amps for typical car stuff so im working with maybe 270 amps

270 Amps x 14 Volts = 3780 usable watts (assuming your yaris sustains 14v typically)

Whats more important is the idling, I should get around 140-150 amps at idle but we'll see. Im the worst skeptic

if you're a skeptic... then change your equation.. 270*13 = 3510

when you have a bass hit, it's not uncommon for your voltage to sag 1volt, also... that alt will charge your system quickly... depending on how he makes the voltage regulator, the voltage may drop down quickly to the mid to high 13's.
