splice the remote wire withe the pink blue stripe wire that goes the the subwoofer switch...

Here's a breakdown of the wires going into the sub. Make sure these wires are properly hooked up at your headunit. Because I'm a techie, I'm going to ask a dumb question. Is the subwoofer button switched to on? Sometimes the easiest things are the ones we miss.

i have the crutchfield wire harness wired up to my alpine harness. so i pluged them in and thats it. yes my sub button was on. so i take the wire from the button thats pink and run it to my pink and blue wire on my alpine harness? or do you mean i have to do the wires up in your diagram wired up to my alpine unit as well as the normal speaker wires, almost as if their was two sets of each?

i told my kenwood that it was a 7x10 speaker and cranked up the through put and that little sub bumps enough my girlfriend complains its too much bass , i also turned up the WoW settings so it pushes more bass to the rear

As far as I know, the sub is being fed by the Right Rear and Left Rear lines from your head unit. First thing I would do would be to turn the fade all the way to the rear so only your rear speakers and the sub should be firing. If there is nothing going on back there, then I would check the harness. It wouldn't be the first time I saw a Crutchfield harness that was mislabeled. When I had my Crossfire, a few of the wires were flipped.

I dont have anything wired up to the wires going to the sub switch, and plus their was three harness's unpluged from my stock headunit, but i only have 2 connected back up for my alpine. I dont no what the third is, or what i would do with it.

[toyotaoffroadFJ]

just splice the remote wire on your deck to the pink with blue stripe wire that goes to the switch...you have to complete the circuit...2 minuteds and its done

[ThyIrishMen]

splice it so that all three are connected? so that it still goes to the button , but also to my headunit.

The third plug is for the steering radio control of the radio.
Problem I recently had was the
factory harness adapter To radio harness (Kenwood)
was calling for POWER Antenna from the radio. I know the Fj DOES NOT have a power antenna. But I did it anyway. So the sub would only would work on RADIO mode and nothing else. I went back and swap it with AMP remote to stock harness adapter. Work great now.
