Default Would a reducer cause a bottle neck?

Well the title is somewhat of a rhetorical question but serious at the same time.

This just crossed my mind today so i wanted to open it for discussion.

Everyone runs the largest power wire they can for the most efficient transfer of energy no? Reduces voltage drop right? Well based on my understanding this is only applicable in long distances. Such as 15-20ft you would want to be sure to run the right size power wire as a smaller wire would add resistance and cause voltage drop, heat buildup, possibly wire failure. But what about short distances...?

You could in theory power a 2000-3000 w amp with just a single 4g run if it were short enough right? Those that answer no consider the fuse on your 1/0 or larger wire. Its tinny but only for a short distance so little resistance is added.

So on to the question at hand. If you ran 1/0 or 2/0 cable the full length of your runs you could in theory terminate them with something like a 1/0 to 4ga reducer with little if any real impact, no?

I think I will pick some up and test just for fun and for $10 it would make a nice way to terminate your wire to your amps so that if/when you have to remove them your not fighting with thousands of little stands trying to get them back int he hold . Granted a 1/0 to 1/0 would be more idea for that but those aren't readily available from what i see. I'm sure toolmaker or Project DB could make some up.

Possible, I'm not debating the cost or if i could get 1/0 to 1/0 terminals just had the idea cross my mind and it kicked on my dim little light-bulb.

Pretty much like using dual inputs.

It won't effect it for the exact reason you think why. It's too short to make a difference.

I have 1/0 running into every one of my amps. I have VFL 350.4 that was overheating like crazy. I ran 1/0 ofc to it and the change in temp was deff noticable.

The TM ones are like 13.50 shipped per pair last time i checked. I would go with him, cause not all the stinger/knukoncepts ones fit into all amps

Was you running 4ga over a long distance causing the resistance to be high. What I'm suggesting is using 1/0 over a long distance to keep resistance low then poping a 4ga terminal post on the end to make it easy to connect to amps when you pull them in and out a lot. I'm suggesting doing this for an amp that is capable of accepting a 1/0 connection without the reducer and only using the reducer for convince. Not saying anyone should do this either only opening it for discussion because by my understanding of physics it wouldn't cause a problem.

It's just a connection. it can and will flow 100% of the energy through it if the set screws are set correctly.
