Hi people!

I just got a new Infinity Basslink unit and wanted to make the installation to my MAX. I know that I have to pass two #8 wires, one to the battery and another for grounding. There's also a need for a 20A fuse, but I have all this.

Where should I take the signal that goes to the Basslink from? I heard that you take it from the cable that goes from the BOSE amp to the speakers on the rear deck, but I still want to use the 8" subs on that deck. DO I need to splice that wire?

The sub has 2 RCA inputs and 2 speaker wire inputs. Which input should I use?

Thanks!
