I dunno whether the battery for the diesel gem would fit. i have a 500watt amp, driving and fog lights, and now that i installed central locking if the battery goes flat I cant unlock the doors. So I got a expensive but good century battery. I have a diesel gem.

I'm running a 350CCA battery in my TD, as opposed to the factory battery rating of 250CCA. I currently have two sets of driving lights, a basic 4 channel amp and 4 in-cabin speakers and am running them without hassle off a factory alternator.

If you're worried about it, get yourself a much heavier duty battery, ie the largest battery that you can fit.

my lol gem i was runing under car neons, fog lights, about 6 strobs, three 400wattt amps. ruing 4 speakers and 2x 15inch 750 watt subs all on the stock battery and aultinator.

u shouldnt really run a large sterio with the car not runing. (i did yes) but its not good for the battery.

i NEVER had a flat battery (touch wood)over the 2 years i ran it
