More than likely, it's very rare that a
stock vehicle's alternator is large enough to
power more than original accessories. At least
during peak times.
My lights dim when I
play my system at night. Why is this?
You don't have enough power coming from the
alternator to supply everything that is running. Lights
seem be the first thing everyone notices, but running low
voltage can cause real damage to your vehicle. When you
run electronics on low voltage they get hot and that's
when they let the smoke out. Once it gets out electronics usually
don't work anymore.
I grounded my amps with
0 gauge to the body.
The body is a great ground, Right? Wrong,
many cars and trucks have the body mounted to the frame on
rubber pads. They usually have the battery ground running
to the engine and a small braided cable running up to the
body from the engine or a small second wire coming of the
battery terminal. On these vehicles I suggest running
another ground to the body, a heavier one. The original
one was pretty much meant to run only the lights and head
unit. It won't handle amps.
