There is so much information, misinformation, disinformation etc. on changing out a Bose system on a 94 Seville to a self amplified unit.

So where am I going wrong with my plan:
1)remove all bose speakers. install new speakers and wiring to HU.
2)purchase proper antenna adapter
3)try to hook up the power antenna to the blue/white wire.
4)locate the power source (usually a red wire) hook to HU
5) no wiring harness is needed since new speaker wires are installed
