Why are my lights geting dim

Question

I have 2 12" power acoustik and a rockford fosgate 800.2 but when i turn it up and the car is on my lights dim and when the car is on acc and i turn it up my sub amp cuts off like if my battery is dead.

What should i do?

Answer 1

This is happening because your factory alternater is not meant to keep up with the power you are generating...But thankfully the Stereo gods have made capacitors that you put in line with your power cables, they make up for the lack of power in your charging system.  That should take care of your problem

Good Luck
