I am pretty sure it will work out as 10 amps should be about right. You can always try a smaller one but it will probably blow. However you want the smallest one possible for the most protection.
I have had tons of accessories powered directly from my Integra which has 7 extra gauges, MSD ignition, Fan controller and a few other items all directly into the battery. I use an insert that goes under the battery post with electrical connector tabs on it to clean up the mess. The best suggestion I have is always have a really good ground when adding accessories and even create new ground wires if you can. From any electrical area or around it to a neutral spot.
I hope it works out for you and come back anytime you need anything else.
