I am in the process of making an e-call. I am too cheap to buy the high end stuff. I haven't received all the parts for it yet but I cant hardly wait for the last part to come, the amp. I will post pics of the build process as it all comes together. I was just wondering what everyone else has done that has made one. I believe I am taking a different rout than most others have that I have seen or researched. Let me know I am curious, and if you have pics post them.
