New Hertz Build, but 9 line WHAT?
I have built and installed a few systems, but due to life and kids it has been about a dozen years since I built my last one. I purchased the following, but they said to install it with a 9 line wiring of which I have never done. Here is what I have and would appreciate any input:
2012 Ram 1500 Cew Cab
Factory RES Head Unit (keeping for now)
Purchased the following to replace exisiting:
Hertz HCX-165.4 (Rears)
Hertz HSK-165.4 2-way (Fronts)
Alpine MRX-F30 4 CH Amp
Dynomat for doors
9 Conductor Speed wire
8 guage Amp wiring kit
LOC wiring harness (bought before when I had planned on only adding a sub)
My question is, Do I use the LOC harness to tap into the wiring harness so as to avoid taping into the actual factory wiring harness? Or am I missing something?
My plan is to install the tweeters in place of the 3.5 in the dash.
