Making an esc better?

[BrianG]

That's why I want a bigger alternator; because I have a heavy audio system. I would go with a class D amp for my sub, but don't like PWM DC going to a speaker - it just doesn't sound right. So, I'm using fairly inefficient class AB amps; 600w rms for the sub, and 300w rms for mids/highs. Caps help the pulses, but it's still a drain on the power and not good for a stock alternator. I would get a regular high-output alternator, but those usually have less current at idle compared to stock.

Anyway, I wouldn't mind something new. Although, these BL systems are very powerful and efficient. I'd rather see lighter, safer, smaller, and better performing batteries to be honest.
