I know this is an older thread, but I was hoping someone might know where I can wire my turn-on wire for my aftermarket amp?

I'm just doing an amp and 10" sub in my trunk so I was hoping there's something near the rear of the vehicle that will allow this.


I have a 2019 Model 3. Thanks in advance!
 
I'm not sure how the ohmmu can change the way the car analyzes the current draw, but during my testing I found that my setup would work for about a week and a half before it would give me the error code. I'm using the penthouse connection with relay (my initial issue was related to a faulty relay) to power 3000 watts RMS of amplification. I plan on adding one more amp in the future to power the rears and center.
Hello,
Are you running secondary battery?
Thank you,
 
I recently finished my install and wanted to share it incase anyone wants to add an amp to their car:
Did you put any thermal fusing on that resistor? Eventually when resistors fail, they can burn up literally. Probably safe to put some kind of thermal break on that thing in case. Personally, I'm going to use relay and a 16ah headway type lithium battery and forgo the resistor. That way the battery acts as the buffer and shields the DC-DC converter from the big draw.
 
I guess I should correct myself. On a newer AMD tesla you will need a second battery to run safely any amp over 500w RMS depending on the type of amp. In the older cars with intel you can run much higher wattage without the need to add a second battery. the 15v battery in the AMD systems is very small and cannot support high current pulls without making the car think there's an issue and throwing itself into a kind of protection.
 
Hi everyone, just after a bit of advice if anyone can help. I was (casually) recommended a Kenwood KSC-PSW10ST powered subby to install in my 2022 Tesla Model 3 RWD. Specs are 1200W max power, 350W RMS. I have bought it but not yet installed. I'm trying to work out if the power draw is too great or if it's going to kill the 12v lithium ion battery/trigger errors. Any ideas? Is there a rough RMS I should be considering when installing an aftermarket sub?
 
Anyone know if the VCleft wire is still a good choice for a turn on signal for an amp? I have the 2023 M3 LR.
Was also considering adding a manual switch to turn the amp on myself, anyone see a problem with that?
Thanks!

I do not understand why people still use a dedicated turn-on wire. Simply use a lc2i with audio sense and use the lc2i for remote in to your amp/sub. Way easier and the entire system turns on when music starts playing.

Because those signal sense only work with high level input but for such as DAP, Bluetooth directly to DSP the signal sensing REM will not work.
 
FYI, it looks like JL Audio has new Stealthboxes for the Model 3 and Y:
 
Just figured I would post this for anyone else who stumbles across this. The end of last winter I started getting multiple alerts once every few weeks relating to the 12 volt battery not being able to be charged. Tesla replaced the 12 volt, error came back, replaced it again, and still error came back. I debated what to do, and the issues just disappeared as warmer weather set in. This fall on the first colder day the error came back. Turns out the 3 ohm resistor was no longer sufficient, presumably after a software update. I upgraded it to a 6 ohm resistor, and now after 3 months I am still error free. So for those endeavoring on this stereo journey, I would now recommend a 6 ohm resistor.
 
PAC audio now has adapter harness' available for both the can bus (helpful for remote turn on) and speaker connections that are plug and play.
The PAC audio CAN-Bus Interface Module (PAC CP1TSL1+CP1S) is listed for the 12V models. Anybody know of a solution for the 16V tesla models? (late 2022-now)

My 05 Lexus 430 W/ Mark Levinson was my last car, traded in last Dec. for my M3P. I was overall pleased with the Lexus audio, not great but OK. I am very happy with my premium audio, far and away the best car system I have heard. 17 pages and deep in to the Tesla electronics I just don't see the juice being worth the squeeze. Perhaps if I had the basic audio system I would understand.
