Big 3 upgrade
 

Hello all,

Just a quick question, I'm redoing my car stereo. Right now I am running 2 amplifiers (alpine 400watt for interior and a kicker 2400watt for bass), possible adding 2 more or maybe just add a 5 channel amplifier ruffly 1500-2000 watts im considering adding a second battery in the trunk a Kinetik HC BLU Series.

The question is do I need to do the big 3 upgrade alternator, battery ground and engine ground in order to do this?

Thanks in advance

Chris
