[QUOTE="dipitydoo, post: 7463898, member: 567383"] i'm not sure if there is such a thing as 100% 'safe', depending on what you mean by that, but given limited funds, best thing to do is to install system, and upgrade as needed. big three is cheap, so good place to start. minimizing voltage drop can be done through upgraded battery, HO alternator, or both. but really, mild to moderate voltage drop will not result in big audible difference. you should be more concerned with the alternator's ability to properly charge your battery. if you don't run into problems starting your vehicle, you are okay. it may not be ideal, but for practical purposes, it would be 'safe'. i would recommend against a second battery in most cases. that's another load for the stock alternator to charge. upgrading to a larger main battery, if it fits, can help buffer some of the voltage drop, without taxing the alternator too much. it all depends on your listening habits and music selection. two people can have the exact same car and exact same system, and their upgrade necessities may be different.
