Battery question

[Rudy913]

12v is 12v Not sure if you have done the big 3 upgrade? That should be the first thing done when it comes to after market stereo installs.

What’s the big three

What’s the big three

Upgrading the power and ground wires to be able to flow all that juice the sound system is sucking down, usually using a 0 gauge wire or 4 gauge.

Id say if it was working before the alt change, start there. Loose wire? Loose plug ect. Check the wires associated with the charging system. Ive seen wires get hot and melt together. Keep it simple, push in all the fuses in the block ect..

Unless you are running a high compression engine, or living where it gets really cold the CCA of a battery is of little importance when selecting an alternator. Get the highest amp alt you can afford.

Chrome don't get ya home. Get the biggest alternator you can fit. Don't bother messing with A-zone; go find a local starter/alternator/electric motor shop near you.

They can also bench test it for maximum output. Have run into several 100 amp alts that would only put out 60

I think they rate them at 0 degrees Kelvin sometimes.
