My current battery is actually an NRMA one - 2254 Calcium. It seems to be doing OK.
Running a big sound system, you probably don't want to be saving weight on a battery. If it's a REALLY high powered system, you should be running capacitors to smooth the load out on the battery (car batteries hate short, sharp requirements for big power), and if you're running the audio system with the engine off, you want a decent amount of storage capacity - maybe even a second battery, or to do a battery relocation to the boot/rear.

Another good option is the Deka Intimidator. Top shelf quality like the Optima.
Personally i would say steer clear of Century, Exide & most RACV/NRMA/RACQ batteries. The quality is too spotty in my experience.
If you're on a budget I would reccommend either Federal, Amaron or Bosch.
Bosch has recently changed their production facilities overseas, and suppliers into Aust have also changed. So finding one & making sure it has decent warranty support is the hard part.
I would say Amaron is your best bang for buck if you can tolerate the fact they're fluro green. I have never seen a dud, or had one fail under warranty since i've been selling them (which is 4 or so years). Recently had a guy with a Prado replace one that was 7years old!
