I just don't want too much stress on my alternator..

I was thinking I should expand more on this. A battery upgrade when running any high current device is a good idea. Running both positive and negative would also be good. 0 gauge is fucking huge for what your doing though. I run a 150 amp circuit breaker for my system and I'm using 2 gauge. If you have plans to upgrade, 2 gauge will cover the vast majority of what you could want. If you don't plan on upgrading past what you have, 4 gauge will most likely be plenty.

I'm sorry if I'm bursting a bubble but an amp that requires a 70 amp fuse is fairly pedestrian really. You can certainly get some great sound and or loud with it, but until your measuring in kilowatts of out put power, you'll be fine with nothing but some wiring and battery upgrades.
