Do I Need To Upgrade My Electrical if im going to be running a 2k amp in my car? i have a Nissan Versa 08 hatch and wanting to get a sq HDC3 and maybe a BASS CLEF SERIES BC2000D to run it. As im closing into getting everything custom box and everything i see people upgrading their electrical. alternator and a Separate battery or is that for like the more hardcore sounds? or would my stock alternator be sufficient? would my car blow up and make a hole in the earth?
