Bad Radio Reception
Same question here, which color wire from your radio did you connect to the blue wire. I have the antenna connected, but I am only seeing a blue amp wire that has nothing to do with it. TIA, I may have to call Pioneer. BTW its a Premeire 980BT with the usual harness that everyone uses to hook them up to factory harness.
In my Sony instructions for my high end $199 stereo, it shows 2 purposes for the blue wire off the deck. One is for the antenna use and the other is for an amp use. I think you can only choose one.

ok. here is the story. not all aftermarket (ie sony, jvc, etc) have BOTH power antenna and amp turn on wires. some will only have the blue/white amp turn on wire. you CAN use the blue/white wire from the radio as well as the blue to power up the antenna wire (blue wire on mitsu harness). the only difference is that there will always be power going to the antenna when the radio is on. you can also use the blue/white of the radio to power BOTH the antenna AND the amp (that is your solution badbrain).
blue/while - amp turn on - 12v switched with radio - can be use to power amp, antenna, or both
blue - power antenna - 12v switched with tuner - can ONLY be used to power antenna (amp would only be on with FM/AM if you connected it with this)
blue/while - amp turn on - 12v switched with radio - can be use to power amp, antenna, or both
blue - power antenna - 12v switched with tuner - can ONLY be used to power antenna (amp would only be on with FM/AM if you connected it with this)

probably. most people don't realized its powered. all the mitsu aftermarket radio adapters come with the wire in the slot, but not all mitsu's have a wire on the factory wiring end. the evo does. you can trace it a bit to a seperate plug. i believe its a yellow wire on the factory side. i don't remember off the top of my head.
Thanks in advance.

Just wanted to say thanks to EvilBlueEvo8 for the info
I posted this elsewhere also, hopefully it might help others.
The difference is huge, I actually get AM now.

For those confused, antenna on Evo7-9 definitely has a booster and needs 12V.
I had no AM before connecting 12V to the antenna. Basically its like a figure 8 cable, one is the antenna signal, the other goes to the booster.
On the car loom side, the wire is yellow, which then connects to the antenna wire.
For aftermarket headunits, connect the antenna rem (usually blue) to it.
I thought the antenna remote was only to power an antenna mask physically up and down when the radio is turned on (radio - not headunit), but it can also be used to power the antenna booster - when the headunit source is set to radio.
Don't connect constant 12V (usually yellow) to it, or you'll probably get battery drain, if you don't have antenna rem (doubt that any headunit doesn't have it), you could use ACC (usually red)

Hope this helps others with poor reception.
