It’s been months since I bought these and I run one coming off my main battery and then another on my auxiliary battery. I’ve got a huge alternator and running nearly 10K on my set up before I even started to think about what Speakers size or anything like that I made sure that the power and wiring is gonna be top notch. I see almost no voltage drops have not had a problem with these whatsoever.
