Installing a subwoofer and need a little help.

So I bought a Pioneer TS-WX120A, one of those little compact subwoofers. This is my first time installing something audio related. Hooking it up to my stock head unit, I have everything installed except for one wire that Im not sure where to connect. According to the instructions it needs only 2A? Its to power the remote to adjust the bass and gain. I was thinking of doing a add a fuse to the fuse panel behind the little compartment on the driver side.
If someone could tell me where to hook this up it would be great.
I have a TRD sport with JBL audio if it makes a difference.

Posting a photo, will save a lot of explaining lol.

 

This fuse doesn't just power the remote. It triggers an internal relay to power the amplifier, switching on the 10A circuit.
You have several options:

1. You could look at the wiring diagram, there is a power antennae feed that could suffice, but you should make sure it doesn't turn off during CD/Aux play.
2. Instead wire the power from your fuse box, use an "Add A Fuse" that you can purchase from any part store. This will turn the amp on with the ignition power.
?. Optionally you can add a switch to this circuit so that you can immediately cut off the subwoofer but leave the stereo alone. (for when your kid borrows the car and plans to blow up yet another one)

 

I used the 7.5A acc slot and an add-a-fuse

 

Awesome, thanks for the info guys!!

 

how did this end up sounding and where did you locate it?

 

I like it, gives it good base, better sounds quality in general. I have a double cap, I mounted it under the middle head reste.
