how many watt stereo with 60 amp alternator?

Dart Vader,
What kind of terminals are you using on the firewall? I am building a mild retro in my 65 Valiant. Putting battery in trunk, power windows modern a/c, big radio, a lot more creature comforts.

I am looking for better bulk head connectors. as I will put the fuse box where the battery used to be.

Thanks,
