problem is when i turn stereo up and have some bass going the lights (dash lights and headlights) pulse to when the bass kicks in
is this due to
A battery not big enough
B battery not getting recharged enough from alternator
C need a capacitor to help keep a constant power supply?

its on a MK4 astra Sri 1.8

the subs been in a 1.7cdti astra 5 door (05 plate)
and a 2001 1.4 corsa sport and haven't had the problem in either

Need a capacitor, when the bass kicks in, its drawing more power from the battery, which will make you lights dim/pulse.

A cap will hold power and when the sub needs it, it will draw it from there instead of the battery
