I would suggest to get a high quality one, to name a few Rockford Fosgate, Phoenix Gold, SoundStream ... I had a Pyle capacitor before on a Honda Accord and the light still got dimmer once in while when I listened to R&B. I later replaced the capacitor with a Phoenix Gold one and it solved the problem. I still use that Phoenix Gold capacitor in my X5 now. I guess the other capacitors did not hold charge as well.
