Aftermarket sound system

[Robospartan]

Hi All

Does anyone know if installing an aftermarket sound system can be done without messing up the battery system in the Y?

I'm thinking of adding a small system (amp, improved speakers, maybe a bass tube, etc) to improve the sound but wasn't sure if this has been done successfully on the the Y.

Thanks!

With the small 12V battery that the Y has, you won't be able to run a decent multi channel amplifier. You will definitely need a capacitor or even an extra battery mounted somewhere. Another word of caution, the Y lacks, severely in certain areas, proper sound-deadening/proofing. Thus, if you increase the output of the sound system by adding speakers, you are asking for distorted output right out of the gate.

In the old days prior to Model 3 introduction, Tesla used to allow drawing power directly from its 12V battery terminals.

Since Model 3 introduction, Tesla has started to account for all power losses/usage from all known sources (including all outlets).

Thus, now if you draw power directly from its 12V battery terminals, it's not calculated as expected loss and this loss is unknown which will eventually prompt a service center request sooner or later.

To avoid that error message, you need to draw power from known sources such as cigarette lighter, USB, OBDII, spared unused powered sources in the cabin... However, in so doing, it might not enough for your new sound system.

To get more power, some advocate tapping the power from the 400V-to-12V DC-to-DC converter under your rear seat. There's high voltage around there so please don't get into an electrical accident!

Good luck!
