no i dont have a very powerful system at all. all i have is a kenwood deck. it only puts out 200 watts. still got the stock speakers. the only planned future upgrades that will put a drain on the alternator would be some 220watt speakers all the way around. and then possible a small amp and sub, maybe 400 watts, if that.
