I've told them that I am keeping the stock amp to power the center and rear 2.5" speakers while a new amp will power all the other upgraded speakers. I was planning on getting one, but now I'm not sure.
Yes, they are correct that you do not need the line-out converter. You can get a simple hi level to low level rca converter to the amps. Or, if you change the factory head unit to aftermarket head unit and go directly from the pre-outs to the amps or aftermarket DSP unit such as the JBL MS-8 or Alpine PXA-H800. This method gives you the cleanest signal. Just make sure that hi-speed can bus signals are going to the factory amp.
Do, I think they are correct in their statements? I am not sure how the
Crutchfield advisors came up with that logic, when they promote themselves as expects. How do you take the factory component surround sound signal and convert into a full range signal needed for the aftermarket processor or an aftermarket amp. The answer is, a summing device.
The summing device will eliminate the pre determined factory crossover points in order to establish a clean foundation to start from. In many cases here, the subwoofer, front and rear doors. If you need additional tuning, then the aftermarket DSP processor is needed. The center and rear pillar can remain on the factory systems.
Without the summing device, you are stuck with the factory settings. In the JGC, these settings with new components will not sound right as they were designed to be.
Hope this helps and best for now.
