Simple issue means your alternator is not able to supply enough amps to keep the system running properly, recommendation get a capacitor to handle the extra load, it acts like a second battery, when the alternator charges the cap it takes the load off the cap rather then the battery, so the lights and system all run with sufficient power i recommend a 1 to 2 farad capacitor for your system if it is about 800+ watts, you will notice the difference immediately
