Most of the problems I see are due to voltage issues with the battery during crank, etc...

so ... I was thinking about getting an extra battery for my amps, doing this for the comp with an isolator should fix a lot of problems??

I'm trying to do research on these things, but it's hard because I don't fully understand why most components have so low watt ratings. Also 100 watts doesn't seem like much, and since I'm ditching my radio couldn't I use that power source?? I'm pretty sure it's regulated?? Or maybe a high power regulator?? I haven't found any of those yet.
