1800collect : I've often asked people why they use caps in cars. I've never met an electrical engineer that thought it made sense or would work.
I ran a 600W a/d/s system for 7 years on a stock 105A delco alt. I never had a problem, But i was easily able to overload the alt even at 3000rpm. But it didn't matter, under 99% of conditions the alt had plenty time to catch up. Before a/d/s was bought by directed I often talked to the tech support guy, who also told me not to bother with caps.
I had a run of 4AWG wire to a fusebox that split to two 8AWG runs, to the 2 amplifiers. I don't know if i necessarily needed as big as 4AWG, but the price was right at the time
The way the price of copper has shot up since then, I might look into some 24AWG
