I have read the older posts regarding supplying 5v power to the antenna booster pink wire to enhance FM reception. Is there any reason to believe it would help AM reception? I have not done anything with the booster yet in my '04 Cpe, but I'm considering it. I get pretty decent FM reception by just plugging the adapter into the factory antenna wire and into the back of the HU. AM reception is non-existent. I would appreciate any help. Also, to those of you that have posted helpful hints and tips, it is very much appreciated and makes everyone's projects go much smoother.

Is the car tinted? My AM went to s.... when I tinted my lexus

This thread is probably one of the old ones you're referring to.

While it seemed to help my aftermarket radio get better AM, if you read down through the thread someone else eventually said that the module is not powered on when the stock radio is playing AM, only on FM.

All I know, if your AM reception sucks as it is, doing the mod can't hurt

Pics on the how to are gone, wonder if the radio shack part worked? 276-1770

pentavolvo

its a simple 5 volt regualtor

yes the radio shack part works. I did it in my C5. It's like 99 cents.

OK I got the part but cant find out how to hook it up , do you have a link?

markcz

With the metal tab pointing away from you and the black ceramic part facing up, the pin on the left (1) is input voltage, center pin (2) is ground, right pin (3) is output.



It wouldn't hurt to connect something to the tab as a heat sink also.

Thanks ,and on that note I have the D3 and MTX 704X amp after about ten minutes it cuts off , the light flashes and the amp is hot as a **** , is this thing too weak , its a 4 channel 420 watt , I have 4 speakers and the sub hooked ,10" sub ,sounds great whens its working ...

Your gains are probably set too high.

The easy way to set them:
-Turn the gains down all the way
-Put the radio volume on 30 (75% of max)
-turn up the gains until you hear distortion (probably about half way of full travel)

any way you can repost the antenna schematics from that old thread?

markcz

I lost many of my C5 scans when my hard drive crashed a few years ago, but I'll look when I get home from work tonight.

Try posting a new thread in C5 Tech asking someone to scan the antenna schematics. I believe they're in the entertainment section of the service manual.

i would love to see how you have that wired.....the amp seems like it is putting itself into protect, as your impedence is probably way to low for that amp

mojo1

I wish I could tell you , right now I have a cheap amp I am hooking up tp teh sub but its sounds like crap ...

mojo1

Pulled the extra amp , put it back like it was and souds good, until I started the car and I hear the high ignition whine through the systemIt was not there before

markcz

And click here for all of the C5 radio schematics and plug pinouts.

jdmvette

thank you once again mark.

now all i gotta do is get that piece from radio shack and splice it in.

mojo1

OK I did this , got it to sound good and it ran for about 40 minutes before cutting out. I did some research on the whine and I found a thread about a fuse that gets blown in the head unit , Ima thinking that is what happened. If so will the ground loop isolater take out the whine or do I have to tear into the unit ?

jdmvette

for keeping the page in my 1 week folder.

Wanna see a neat trick

- Click on 'add to favorites' or whatever you need to so you can put a NEW shortcut to CF on your browser/desktop/favorites bar/whatever.

- On the red forum bar at the top of this page, click on 'my recent topics' to get the dropdown box there

- RIGHT CLICK on any of the 'days' choices, click on properties

- highlight the entire URL address (you may have to move the mouse pointer down to get it all), right click and copy (or CTRL-C)

- cancel out of the properties window

- Go to the new shortcut you just created in the first step, right click and select properties

- On the 'web document' tab, paste the address you just copied from the recent topics window into the URL line

- At the very end of the URL you just pasted, change the number (if you clicked on the 4 days link it would be a 4) to 30 for 30 days, 100 for 100 days, 365 for a year, I think you get the idea...

- Under the 'general' tab, in the very top box change the name of the new shortcut to something that will tell you how many days you are searching. I made mine search 30 days of history, so my shortcut is named "CF 30 days"

- click OK at the bottom of the window to save the changes

- Click on your new 'CF 30 Days' shortcut link and it will display every thread you've posted in for the past 30 days

HAPPY SURFING

FYI, the search results will only display 250 threads, so searching 3000 days in an effort to see all of the threads you've posted in won't do much good unless you haven't posted much.
