OP,
glad to hear you figured it out. not sure where your original post was but I think the audio section its pretty slow. better off just posting in the 3rd gen section.
if you want to search for a topic just use google or bing to search the site
directly. You will get much better results.
TIP:
enter into google exactly like this >
site:toyota-4runner.org searchWord
btw when the forum says
thread views, those include clicks for outside like google, not necessarily registered members. It makes it look like everyone is ignoring the post but really that isn't often the case. Also if you want better responses make the post clear and easy to read.
Noise
Make sure your head unit is powered directly off the battery with a 25-30 amp fuse. If you have a separate amp, make sure that is powered with a separate cable to the battery.
I have NO noise with this setup. If you have noise when playing from a phone or MP3 player check if your ipod is pluged into 12v, unplug it and try using just battery to see if the noise goes away. In my truck the only time I have ever heard "feedback whine" is when I charge my phone
while playing music through the 3.5mm jack.
The next step to eliminate noise is to run your own 14g speaker wire to all doors.
Antenna
All, you should not need a separate manual switch for the antenna. I have an alpine head unit and I wired it to the factory harness. the antenna goes up when I have the radio on FM/AM only. if I power it on to use just CD player then the antenna stays down. this is similar to the factory setting.
maybe the radio you bought doesn't support this setup but all alpines do. there is also a possibility you are wiring it wrong.
PS, it makes it a lot easier for others to read if you separate your post into small paragraphs
