Is a 1 farad capacitor enough for a orion 2500d amp or should i go with a 2 farad? Also will a 2500d accept 1/0 gauge ring terminals?

there are two 4 awg inputs(12 volt) and 2 4 awg grounds. assuming you have stock alt, a cap may help, but in the long run you should get a new HO alt, a nice batt(yellow top or orbital), do the big 3 and then you should be fine. Remember, that amp has been tested and at full tilt it will put 300 amps, a stock alt is probly only good for about 60 at the max on a car, some vans and trucks have 100-110 amp alts.

but if your dead set on a cap, get a 2 farad. im not 100% sure on this, but i remember hearing that every .5 farad is good for 500 WRMS. so if its a DD then you prob wont pull more then 1500 WRMS for long periods of time, so a 1 farad should do, but for the price you should just get a 2. but then again for the price, you could do the big 3, you might get more out of your system doing the big 3 then you would if you got a cap. even just upgrading the batt-ground would make a big difference, seeing how most car companies dont get a baremetal contact on the ground. the just put the ground wire over paint...

whats the big 3 ?

wire upgrade, do a search youll find TONS of stuff on it. pretty much rewire all the wires off your alt(alt-ground,alt-batt)and your batt to ground.

That amp will pull huge current. If you're using it for SPL comps then skip the cap and just get the biggest batt allowed/fit.
If it is for daily driving then skip the cap and use the money for the biggest H.O. alternator you can find.

If your wanting a cap, rule of thumb is 1 farad for ever 1000W rms. The amp will produce slighty over 2500wrms so I would say 3 farad. Not to mention the rest of the stuff (Batt, big three) as so on
