I’ve been looking around for information on and off for about a year now regarding adding an aftermarket subwoofer and amplifier to my car. Anyone have any experience and want to share their setup or issues?
For some other info, I have a 2022 Model 3 P with the factory subwoofer in the trunk. My car has the AMD system with the 15V Li-ion low-voltage setup which is why I’ve been seeing conflicting information.
I’d like to avoid the second battery route, so my options are somewhat limited.
Based on what others have said on here, Reddit, etc., I think my options are as follows:
Any help would be great. I can also link some of what I’ve read if needed.

Based on what others have said on here, Reddit, etc., I think my options are as follows:
- 300-500W sub
- Use a LOC to covert the signal from the factory amp. This would also allow me to use the audio signal as my remote (like on the LC2i Pro) for the amp.
- Use a 300-500W amp (depending on sub) that gets its power from the backseat penthouse.
- Should I stay safe with the 300W sub/amp or can I go with a more powerful 500W option?
- What adapters would make it easy for me to get the high-level signal from the factory amp so I can feed it into my LOC?
- Would the higher voltage (14 to ~15.6) from the penthouse be too high for an amplifier?
Any help would be great. I can also link some of what I’ve read if needed.
