Big 3 difference

[BlurredVision 10+ year member]

So I recently had a shop install me a stereo. Love it. It's my baby. 2 DB Drive wdx 12s and the mini a7 2000. Their 85.4 4 channel and memphis PRX comps. Hits hard. I upgraded my battery and decided to do the big 3. I upgraded the batt neg to ground and it got fairly louder. Today I upgraded the batt neg to frame and i got a lot louder. I can barely hit words now. When I do the power wire I can only imagine it'll get significantly louder again. Is this normal? It's literally blurring my vision now. I also had my edge sound deadened, which is already a quiet ride so it's all staying in.

The bigger wires makes your charging syatem more efficient therefore getting more power to your amp letting it run at a more efficient power therfore itll put out more power

It is astonishing the difference it makes. It went from feeling the wind to violent shaking and I'm not done yet.

The big 3 doesn't give more power. It only gives the power being supplied by the alt to recharge the battery faster more efficiently which in turn sends the power to the amp faster. Not more

Yea sorrry i missed a word there ment to say more efficient power to the amp but then again i might have it all wrong just going off of stuff ive read online

But is this typical? Were my amps that starved even with a batt in the back?

Yes amps need current. Battery power only works if you have a ginormous bank. Even then you have to overnight trickle charge them every now and then.

Correct a newb if im wrong, but adding even a single battery in the rear is simply not enough. that battery will not even come into play until you've successfully pulled down the alt volts to 12.8ish(secondary batt voltage)

after your volts are pulled down to 12.8v, then the secondary battery will start the conduct amperage and maintain amp load at 12.8 volts. thats only gonna keep your amps powered at 12.8. most cheap amps are rated at 14V output.Dont even have to be a cheap amp per se.

Hence why there are 14v and 16v batteries. both those systems require higher voltage alternators than the battery their charging. Some vehicles require 12v isolation for computer(Honda) , some dont.

although i just started learning, and could be wrong. So feel free to correct anything you feel may be misleading.

How long have the subs been in? There probably getting louder as they break in. But your amp will love the big3.

You cause be right on this. Had them about a week and a half. Added the power last night and that didn't sound louder but I can imagine event is very stable. I gotta buy one of those outlet voltage meters.
