Any update? I'd love to hear from the people that have actually at least attempting a more scientific approach to this.
File me a skeptic here as well. I'd consider myself pretty knowledgable in both car audio and DC systems and I can still only see 2 possible outcomes as to why anyone that installs this Ohmmu battery hears a sub difference.
1. The LA battery is faulty and can't provide the current needed. (No way this affects highs)
2. Replacing the battery causes the audio system to recalibrate which raises the gain on the sub.

I just read through this thread because I want to install a subwoofer. All was going well until someone mentioned installing an Ohmmu battery. Now I’m totally tempted to start there and then upgrade my sub. I too had a 1 farad cap in the 90’s and know the difference it made.
I just wanted to chime in and add that my December 2019 built Model 3 already had the 12v battery replaced once (I blame a faulty dashcam install). I remember the tech had to unplug a cable under the rear seat to replace the 12v battery. In any case, my audio and bass performance did not improve with the new battery. In fact, I would argue there was no change whatsoever. As an audiophile and coming from an amazing Bowers & Wilkins system (and previously Focals), the premium audio system leaves much to be desired.
After reading through this thread, I think I am going to purchase an Ohmmu because I don’t want to risk getting an error after installing a sub. If there is an improvement in soundstage and the highs lose the harshness I am hearing, this will be an added bonus. If the bass response improves, even better! The way I see it, if the battery makes the stock sub sound better, my aftermarket JL sub will definitely see an improvement.
I will share my feedback after swapping out the battery.
