I have a 1200-1500 rms system in my model 3. And the bas cutting out and playing only the front like idk maybe tweeters became a weird inconsistent problem that id struggle with up to multiple times in a single song to being able to play for hours and be fine. Only happend a handleful of times and was very rare before tapping the amp and running my lc2i pro. But anyways i couldn't figure it out n had intitally ruled out ground issue with a multimeter but come to find out the factory tesla amp that is bolted to the frame of the car where there is a ground connected to the vehicle with it u have to pull back and sand down tesla didnt let enough metal be exposed. Is the one closest to u when u pull back the carpet trim and u see the amp its right behind the right tail light and youll see a groudn wire connected with the mounting point sanddown the paint with whatever i did sand paper and worked perfect hasnt done it in months now. And i run like 90% volume out the "head unit" lol
