Question about input voltage and gain

[LoganSheehan 10+ year member]

Ok so my amplifier is ~ 1150w rms at 2 ohms

According to some website calculator i should have ~ 48 volts coming out the speaker terminals

I played a 50 hz test tone with all equlization off and 3/4 volume on cd player

And set the gain until i got ~ 48 volts

My question is say I am using wires that are too small.

Say 5 gauge power for 1150w rms and 6 gauge ground

I KNOW this is to small and my 0 gauge should be here thursday ...

I plan on doing the big 3 as well when they arrive

Anyway, will larger wires make my subs louder ?

And when I re-do my wiring ... Should I reset the gain or not ?

Say im getting 12 volts of power to the amplifier

If I re-wire and then get 13 volts it will be noticably louder ?

Im just confused haha someone clear things up for me.

If your gains are set then adding wire wouldnt make them louder, it just helps with your voltage drops. It will be loud on a consistant basis if its getting the right voltage, verses if you were getting drops. From 12 volts to 13 volts isnt a whole heck of alot and you probably wont notice a thing. I took my step-dads car that had 8 gauge one day and put 4 gauge in it for him for something to do. He didnt notice a thing.

5-6 gauge is plenty, actually. Most people just go bigger because they can, not because they need to. Kinda like having 5kW on the subs but only ever actually getting 1500 or so to them with music.
