Do i need a new alternator or the big 3 upgrade?!

[UrMomsUnclesDad]

So i have a 4ga Wire installed for my current amp and im thinking about getting a Crescendo BC2000d. I know i need 0 ga wire now but now im wondering if i need another Alternator or big 3 upgrade.. thanks in advanced!!

Do the Big 3, add some ofc 1/0 gauge and watch your voltage. Contact tenneyalts.com aka Skee on here, he will point you in the right direction. Also he sells cable & big 3 upgrade.

Yeah, pretty much what he said. If your voltage is dipping down past 12V, you can add in a battery before you step up the alt (makes more sense price wise).

Add batts and big three. I ran a nendo 5500 on a red top and an HC2400, voltage stayed right around 12v playing music full tilt. I have a stock alt. but every Car is different. Install and test your voltage. Upgrade alt if needed.

Oh okay so a voltage meter is a must along with the big 3 and possibly a new bat/alternator. thanks for the help guys!

easiest volt meter

voltmeter

add battery first and 0 gauge wire.

I am running 1700 and no alt upgrade and has not done the big 3

Also why battery first?

Grab a xscorpion or stinger voltage meter so you can get the vote from the amps.

Cool find, batt is cheaper than alt, u might Not need alt upgrade

[bass wrench]

proper Power wire to amp (no CCA), do big three under hood, good ground at amp, now if you have voltage drop, add rear battery, still voltage drop, upgrade alt,
