Well some amps have the different inputs to deal with the fact that some active basses have very high outputs etc. (Though this is the case with some passive basses as well lol) But otherwise, even with an active bass, you can simply plug it into any amp.
Beware of small 15 watter amps though, they may not handle the high output very well. Me advice is to get at least a 25 watts... besides, if your amp is too tinny you won't have the satisfaction when you are playing even if its just at home.
