ok so i really want to keep the stock head unit on my 2011 tc and well i want to connect my sub but i dont know what cable to hook the remote to. i know theres threads about this and all but each thread says to do something different. on the picture i have the yellow red light blue black and white cable. which would i hook the remote to or is it even those cables? is it on of the cables on the left? i am also trying to crimp it with the blue thing if thats what its called because i dont want to cut into it or anything. please help!. thanks. oh and as you can see in the pic i already tried the red and yellow wire but the amp doesnt even turn on!

 

I just use a t-tap and tapped into the red wire on that harness. That's you ignition wire on your stereo so you will have your amp turn off with the ignition. If your amp isn't turning in check your connections and make sure your splicing into the far right side (your right as you face the stereo) connector.

 

yea well ___ you can see from the wires you can see that i already tried with the red and yellow wire but the amp doesnt turn on at all with the yellow it should turn on cuz thats a constant 12v right? and well i tried the red too but no luck. could it be that they are not connecting right? and i know everything is connected right because when i plugged in my aftermarket pioneer the sub turned on!

 

Oh make sure your sub woofer controls are turned on. Your stock stereo has a control for that. I believe that's the only way it will send signal down the RCAs. You said you hooked up an after market pioneer stereo and everything worked so this may be your problem. Yes the yellow is 12v constant but I wouldn't leave it hooked to that your amp will drain your battery.

 

When radio unit is off, hold down the enter button down till the option screen turns on. Then go to SB woofer setting, then turn on.

 

Tried that but still nothing I can here the difference in the sound but no sound comes from my subwoofer I don't think my amp turns on at all

 

Do you have an indicator light on your amp? Are you getting sound from your subs at all?

 

yes i have a red light in the middle of the amp and it doesnt turn on! why!!!??

 

Check your fuses on your amp... That may help.

 

but im telling you it works cuz when i connect my aftermarket stereo it works fine! this is how i have it connected

 

Ok so I works when an aftermarket stereo is hooked up which means its something to do with your stock one. And you made sure your sub woofer settings are turned on? That's the first step the second step would be to see where your base levels and sub woofer levels are set in your settings.

 

yea. when the radio is turned off i leave the ssp button pressed then go to sub and turn it on. but no sound comes from the sub!
do you think the wire might not be getting connected right? is it fpr sure the red wire for remote?

 

Ok. Make sure in your audio settings your subwoofer level isn't turned to like -10 or something low like that.

 

its not man. im getting frustrated with this!!!! im pretty sure my amp doesnt turn on though cuz the light of the amp doesnt turn on!

 

Hmmm... Well that perplexing then. You have everything hooked up the same way you did on your aftermarket one? If it works one way but not the other then that means something is happening with your stock unit.

 

What head unit do you have? Is it the basic pioneer or any of the upgraded ones? This may help.

 

its the basic one with the rca outputs.

the amp doesnt turn on at all with the stock one. just to make sure which one is the cable im supposed to connect to? and also do i need a converter?

 

You shouldn't need a converter, the blue amp wire should be hooked into the red 12v ignition wire.

 

So Just to make sure im supposed to connect the blue remote wire to the red wire on the 19 pin or 6 pin connector?

 

Another thing you can try is to hook your remote wire in directly to you 12v line on the cigarette lighter port. That will give you the power you need and see if your amp turns on that way. Mine is in the 19pin I just double checked but either should work they are both 12v ignition... Honestly I would just tap into the cigarette lighter. Saves the hassle and it is perfectly acceptable your amp will still turn on and off with the car.
