Ok so it seems completly insane. What I want to do is find a way to run my old deck as my media center within my house. My problem is simply that I cannot power the device. I have a battery and power adapter from an old ADT home security system. The adapter has a 16.5v load. The battery has a 13.5 - 13.8V "stand by use" and a 14.4 - 14.7V "Cyclic use". In the top right it said BD 4-12 Which I assume means 12V, 4Ah. So That confuses me a bit. Anyway.. The deck I would like to use is the JVC Jensen MP3310. I have everything other then powering the unit worked out. So I would greatly appreciate it if someone could possibly give me a hand.
