This review is so late, i bought this product over 2 years ago. It still works and still delivers full power to my 2 pioneer champion series 12 inch 1200watt subs which I have hooked into a 2400watt power acoustics amp. My lights used to dim before now they don’t. All auto shops I’ve been to suggest extra batteries because of the strain that caps can create on a alternator but really its an efficient way to get what you need for your system and this cap is well worth putting in any vehicle. All my led lights still work no over currents and is mad easy to install.
