hey guys this is me first post. Just a few questions..
I recently purchased my first car, a 1989 jx sierra with 122000kms on the clock

.
Anyways so far i have installed snorkel and spotties. However when im driving at night, spotties and head lights on
stereo blazing and a small led ligh strip on my battery power seems to get pretty low.. luckily llast time i had just enough
to start my car as i stalled iy and couldve been stuck out in the bush.. however no problems with alternator as battery charges when all this gear is turned off.. any suggestions as what to do so that my power supply can handle the gear im running??
