Few more questions about audio.

1. Splits can offer better staging, and aside from that, I'm pretty sure you can make better quality drivers if they are both seperate.. you don't have the crossover, tweeter and woofer all in one thing... But imo, it's worth the extra effort.

2. I would get fused, just to be safe... It's not needed, but I just prefer to be safe than sorry

3. Yes, that is correct, only run positive back from the battery. Your grounds will come from a bolt nearby the amps. As close as possible is recommended. The idea is to get something that bolts directly into the cars body or so, and rub away any paint, so it has direct metal to metal contact.

Ok, thanks. Do you know what fuse I would put in the distribution block? 200A near the battery I know. Off the dis. block there would be a 200rms 2ch amp (100rms X2) and a 600 rms amp both at 4Ohm. So would I need something like a 50A fuse in there if I was running 4ga wire to the amps?

EDIT: also do I need to run a fuse anywhere on the big 3 upgrade? In one video i saw a guy put a fuse inbetween the battery positive and the alternator (close to battery). Not sure what size it was, guessing 200A or something.
