i put a pioneer head unit in and ever since my reception SUCKS. i have the stock antenna, and i made sure the antenna is plugged in the back of the unit.

is there any antenna boosters out there? hows it work and how hard is it to do?

thanks

did you make sure your antenna power is connected when you install the head unit? The Z already has an antenna booster.

 

dont know about that...i just hooked the colors up to the matching colors...tell you the truth i didnt see anything like that in mine.

 

Hooked the colors up? How do you know that the colors corresponds to the factory ones?

The anntenna Amp is pin 5 (G/W wire, guess that's Green/White)
On your 10 pin factory harness it'll look like this

2 4 - - 8 10
1 3 5 6 7 9

You won't see the Antenna amp unless you remove all the panels from your trunk. (see pic)

No point in buying something (ant. booster) you already have stock. Just make sure you connected it right.

 

so i hook up the g/w wires to the power and ground of the headunit? how do i know which one is ground the green or white?

thanks by the way.

 

I experienced an extreme degradation in performance of my tuner after I installed a new head unit myself. Can anyone please explain exactly what wire from the factory harness needs to be plugged into the Metra wiring harness in order to utilize the factory wiring antenna booster?

 

no no no. Your headunit should have a wire for the antenna. You hook the g/w wire to that. The g/w wire is the power, and the antenna (the one you plug into the headunit) is the ground. So if you didn't wire the g/w wire to the HU, the antenna amp is not turned on. Hence bad reception.
Look at your Headunit wiring diagram, there should be a wire for Auto Antenna (or something similar)

The g/w wire on pin 5 (out of 10) is the wire you need to hook up. (see previous post)

 

The remote turn on from the HU is blue and I'm assuming the wire in the harness is too. Without it hooked up you'll get about zero reception.

 

thanks guys, im gonna try that out after work if my flights cancled. ill let you know how it goes.

 

I think there is still some confusion going on and I am going to try and clear it up. On most aftermarket radio wiring harnesses there are 3 wires that don't always need to be used. They are as follows:

Amp Turn On Wire (usually blue): Used to signal the amp to turn on when the radio is turned on so it is not always running wasting your battery. If you aren't using an amp then don't worry about it.

Illumination (usually orange): Allows the radio lights to dim along with the diming of the gauge lights when you turn on your headlights. If your stock head unit doesn't dim then don't worry about it.

Power Antenna/Antenna booster (not sure on color): Allows the radio to raise a power antenna when the radio is turned on. This can also be used for an antenna booster because it will turn on the booster when the radio is turned on. Otherwise the booster will waste your battery.

 

welli just did it and wow, HUGE difference in reception! i saw the green/white wire but i didnt see an antenna wire, so i hooked it up to the ACC and it works beautyfully. thanks alot!
