Re: When to upgrade to high amp alternator?

PS, are running a capacitor between your amp and power lead? The pull that a decent can put on your charging system can be significant. A "cap" stores that energy for the amp to pull from rather than overly taxing your alternator. I have a 1200w amp in my 06 Sierra and a 3.5 farad cap ahead of the amp. Even when I push the amp my headlights don't and dash lights don't dim with the bass hits. I hope I'm being helpful.
