i have an aftermarket stereo in my car and when i turn up the volume it makes the battery gauge drop and the lights dim when the bass hits which eventually lead up to me not being able to start my car without being jumped then to where i had to change my battery and disconnect my stereo from the battery before it starts now. my stereo is made up of an alpine 9887 deck, mtx thunder elite 1004 powering mtx thunder 6.1 high end components and alpine type r 6x9s, and an mtx thunder elite 1501d powering a single mtx thunder 9500 12". the stereo is run through a 2 farad capacitor with streetwires and was installed by my brother in-law whos been installing car stereos since he was 17 now in his 30s. does anyone know whats going on and how i can fix it?
