Reviving this thread for a little help with install of an Atoto F7 XE. I have somehow convinced myself that some forum threads and you tube vids has given me the knowledge to install a stereo, even though I've never done anything like this.
I think I have purchased basically all the wiring harnesses IN THE WORLD for this project based on this and other threads. I have a 2012 P4X with non-nav RF system. I am trying to "simply" replace the head unit and retain the RF woofer and SWCs.
I purchased
both the Metra 70-7552 (w/ swc) AND the Metra 70-7553 (w/ rca connectors for the speakers). To retain SWC, I have the BT bypass dongle thingy, and to avoid the popping I have a 4 channel ground loop whatchamacalit.
I thought the 7552 and 7553 would somehow work together, but obviously they don't, and now I have the age-old problem of too many female ends (99 problems...?). Sorry.
Anyway. Since I have these stupid things, can anyone help me understand how to merge the two Metras to make one usable harness? Would it be better to use the 7553 and harvest/ splice in the swc wiring from the 7552, or vice versa (harvest the RCA wiring from the 7553)? Do I actually use
both 20 pin plugs somehow? If so which harness wires go to the Atoto harness? Should I just take all of this to an installer? I can change a motorcycle clutch out, but I feel over my head with this...
While I'm at it, on this RF sub being over-driven by the 4 ohm outputs, would the ground loop isolators I got do anything to combat this issue, or do I need to get YET ANOTHER device to cram behind this stereo? Would I use the Scosche SLC4
instead of the ground loop isolators?
