Unless you run the 4 channels on the amp to full power, I wouldn't stress the alternator.

Before doing my auxiliary battery setup, I was running my 300w RMS underseat powered sub off the car and the alternator wasn't complaining. Only when I was running my 1000w microwave on the inverter that it sounded suspicious.

Yeah, the sub, an NVX QBus8v.2, is 100 watts RMS and 200 peak. I don't expect I'll be cranking the system up very high, but I don't think there is much headroom in the alternator after everything else in the car is supplied. I was looking at a 140 amp alternator, just not sure I'd really need it. I've also been looking at big 3 kits.

Would you mind elaborating on a bit on your auxiliary battery setup?

Thanks
