    800W RMS Amplifier install on 2022 model Y with new 15.5V Li-ion battery/AMD system

    I wouldn't run from the front battery, yes at first it works but at least for me, over a few months of banging beats, the bass got weaker and weaker... switched to penthouse and back to banging.. although side note: my ground wasn't perfectly grounded so that MIGHT've been my problem. lmk

    800W RMS Amplifier install on 2022 model Y with new 15.5V Li-ion battery/AMD system

    I have my 500w amp banging beats for about a month now hooked up into the penthouse. I would like to say it has been going smooth but I've had 2 instances where I get the LV bad quality error. And going into service mode I have the "sharpCurrentRise", error. I am now setting up a full...

    800W RMS Amplifier install on 2022 model Y with new 15.5V Li-ion battery/AMD system

    That makes way more sense now! I appreciate the in depth response. Also; you used a 14v amp right? Or a variable one? I couldn't find anything on your specific amp on which input volts it takes. thanks!

    800W RMS Amplifier install on 2022 model Y with new 15.5V Li-ion battery/AMD system

    Can someone explain to me why putting a 15.5v and a 14v battery in parallel isn’t a bad idea.. because google says not to put any batteries of different volts in parallel.
