Upgrading my alternator

[offroadfury6]

Nope. Big 3 won't help amps or sound either. Either your alternator makes enough power or it doesn't. However, very few people reach the extents of their alternator with daily audio.

When you "crank" it you have maybe 10 watts going to a single speaker. That's 40 watts for four speakers. Add a sub...maybe 60 watts total. Let's say the amps are 50% efficient. That means you're drawing 120watts. No reason for 0awg, big 3, alternator, etc.

Most of what you see people installing is snake oil and advertising. However, this is assuming you've set up your system correctly too. Misalign your gain, create some square waves and all hell breaks loose.

I dont understand why caps are trash then.
