I have a 2800w e3 massive amp and a 1000.4 amp bp massive amp after an electrical upgrade. I still had problems with the voltage and dimming of the headlights. I installed Massive Rail Cap-BLX and it solved the problem. The voltage is normal, the headlights no longer dim. The device was very easy to install and connect directly to the e3 amplifier. I highly recommend this product.
