I have a car show to attend on sunday and I am planning on running my new orion 2500d that I havent used yet. I plan on running it at 1 ohm. This was an unexpected show so I have 2 upgraded batteries but the stock alternator on my 95 eclipse. How many amps will the orion 2500d pull. Will I be okay if I dont play it at all until the show? I plan on running 1 15 at 1 ohm in a 5 cubic foot box. Quick responses are extremely appreciated. Thanks guys.
