I was a little worried considering that most capacitors cost around 4 times as much and sell for over $30 USED, but so far I’ve had no problems at all. It fixed the dimming of my lights, and has more capacitance than I’ll probably ever need, even if I upgrade everything else.The design does have one minor flaw though: If the fuses on your amp blow or are removed (I did this as an easy way to disconnect the power to my amp), the capacitor will go into protect mode and an alarm will start going off. The only way to make this alarm stop is to disconnect the capacitor’s + terminal and wait for the noise to stop.This will drain the capacitor down to around 4V, but use a multimeter to make sure it’s not close to 0V, otherwise you’ll blow all your fuses when you hook it back up. If it’s close to 0 you will have to recharge it with a resistor. If it’s at 4V, you can just hook it right back up. This is annoying, but acceptable because I don’t plan on blowing my fuses too often.
