I have a 200 watt HiFonics Zeus amp and a 10" Image Dynamics IDQ10 D2 woofer that I used to have in my Jeep and has been sitting in my garage for several years. Just got a boat and decided I should install it in there and get a little bit more use out of it.
I have the location and the box design figured out (In the driver's kick panel) but I've only wired up amps in cars in the past. Is it safe to ground this small of an amp to the grounding block or do I need to run it all the way to the battery as you typically would with the positive cable?
What gauge wire should I be using?
Long term I probably should run a fat cable up to a distribution block so if I add an amp for tower speakers I'll be ready but that's big $$$ and I've spent enough on the boat for one season. I'd rather do something cheap and sufficient and then redo it (or add another small wire) later if I end up needing to.
