Thanks for information, sadly i don't think removing picture will do anything since you can clearly see that ring back on every picture in next step. Most of the times that paper ring is not holding on cell with glue so it will fall off, this is just precaution to not throw it away or forget about it. I am however gonna bold those important things and add warning.

These are all basic things, not really worth mentioning.Congrats on your first instructable though.

Agree, but when you have a lot of power and much bigger system than stock then you want something like DSP to take care of it all. You don't really want to blow your 1000$ tweeters because you ran them too low.
