  • Good for its price compared to others
Turns screen off automaticfally after 5/10minutes of use. Works perfectly for my Corolla 2011. Helped with load to my amp and battery feel more comfortable with the power draw. It’s voltage mattches the cars and acts as a mini storage unit but it’s more efficient to use it as a buffer between power and amp. It was medium easy to install issue I ran into is the wire hole was too big for the screw so I use a washer. For 5.5F I needed 3000W and it’s perfect will update if anything appears ... show more

  • Meh....
Update 05/21 - it stopped working completely. So this thing is total garbage. I've sold and installed car audio for 20 years and have never had a cap fail. Good thing is it quit working in enough time to return it. Does about as good as the Scosche 1/2 farad you can get at Walmart but it looks better because it's wrapped in black. Gives up the ghost on a 2k mono block MB Quart so it's not like a lot is being asked from it. 5 farad should be more than enough for 2k. ... show more

  • It worked lol!
The media could not be loaded. Packaging was damaged the resistor that came with the capacitor to charge it was broken I had to find other means to charge the capacitor but since charging the capacitor it’s worked perfectly and has not given me any electrical or voltage issues.
