Hooking up sub to factory nav.

Okay, I've owned about 30 cars and all have gotten a sub/amp put in them at some point. But still not quite sure/happy with the current installation on my new truck. Really just confused since nothing seems to be what I have read.

2012 with factory nav and subwoofer. I have installed a Lockpick, at JX500/1D 500W RMS Amp and a 13TW5-3 13.5" Single Sub. along with a 4 gauge wiring kit.

First problem I ran into was the splicing off the factory sub turn on wire wouldn't turn on the amp. I've read that this is a 5 volt lead so I assumed that was the problem. Ran a turn on wire to my Lockpick to bypass. Amp turns on now.

Second issue was hooking up the factory speaker lead wires on the harness. I read that these were high level so would need a low-level adapter. My amp had one built in so I used it. The problem was the sub volume was MUCH lower than the factory sub. Find out that those on the harness seem to be low level already. So I fashioned up an RCA cable to attach to the factory leads. Sounds is WAY better but I still don't think it's perfect. Having the gain on the amp turned all the way up and with the bass boost turned all the way up there still isn't hardly any clipping. Still seems like the factory leads aren't putting out enough power considering everything is maxed out.

My final problem comes down to the dreaded turn on "pop" when I start the truck. I have narrowed it down to being RCA related as the pop doesn't happen with the RCA cables disconnected. I suppose this can be fixed with an RCA "pop eliminator"?

Really just sharing my experience to see if others had the same problems or could possibly help others in the future.

I don't recall off the top of my head but I know there is a thread within this forum that shows the wiring diagram for just that sub harness.
