I have an '04 infiniti g35 coupe with the factory bose system. I want to replace the bose amp that sits in the back of the car. The factory HU has plus and minus outputsfor each speaker to this amp that are shielded. This is unusual, because usually speaker level inputs are not shielded. On the other hand, usually when you send a signal to an amp it is not at speaker level. So here are my questions:
1. Are these leads high level or low level? Where can you get this info?
2. What adapters are available to bypass this amp to use an aftermarket amp?
(I am installing an Alpine V12 5 channel amp that has no speaker level inputs.)
3. Would an LOC work here? Which one would work?
4. Is there anything else I should be thinking about?
