Hi,

In continuation to my earlier post 

I found better way of using stock AMP with after market radio.

 

Warning: DO AT YOUR OWN RISK. I WONT BE RESPONSIBLE IF YOU MESS UP.

 

What you need.

1.       Arduino UNO (I think you can use Nano also)

2.       CAN Shield 

https://www.dropbox.com/s/lmxbs6dnu5scp1b/MCP2515-CAN-Bus-Module-TJA1050-Receiver-SPI-Module-for-Arduino.jpg

3.       CAN Shield library (https://github.com/coryjfowler/MCP_CAN_lib)

4.       7808 Voltage regulator

 

Step 1:

Download and extract Arduino IDE and CAN shield library

 

Step 2:

Connect CAN Shield to Arduino as per below diagram

Step 3:

Connect  Arduino to PC, compile and upload below code to Arduino

 

#include <mcp_can.h>

#include <SPI.h>

MCP_CAN CAN0(10);     // Set CS to pin 10

void setup()

{

  Serial.begin(115200);

  // Initialize MCP2515 running at 16MHz with a baudrate of 500kb/s and the masks and filters disabled.

  if(CAN0.begin(MCP_ANY, CAN_100KBPS, MCP_16MHZ) == CAN_OK) Serial.println("MCP2515 Initialized Successfully!");

  else Serial.println("Error Initializing MCP2515...");

  CAN0.setMode(MCP_NORMAL);   // Change to normal mode to allow messages to be transmitted

}

void loop()

{

  // send data:  ID = 0x100, Standard CAN Frame, Data length = 8 bytes, 'data' = array of data bytes to send

  unsigned char stmp0[6] = {0x03, 0x00, 0x00, 0x00, 0x00, 0x00};

  byte sndStat0 = CAN0.sendMsgBuf(0x507, 0, 6, stmp0);

  delay(5000);   // send data per 5000ms

}

Step 4:

Build 7808 Voltage regulator, as per below diagram

Step 5:

Connect Arduino to car. I placed my Arduino inside amplifier(saved me extra wiring hassles)

That’s it.. If all goes well you should hear sound from stock amplifier

Use this connection diagram in step 2
