looking to do a stereo install and the SC will come after...

Stereo = roughly 1600W (3amps + 1cap + optima red)

i like to run a separate batter in the trunk for the stereo and i understand that i need a smaller battery to accommodate the SC under the hood... so give me an opinion if i can get away with just one battery and what is the benefits of either method. Planning to do the big 3 (upgrading wires) as well. what gauge cables would you recommend and please give me ur advice.

Thanks

 

nothing less the 0 gauge audio cables for the system. And you probably should of posted this is the audio/video section
