After Market Double Dinn

[david49west]

 

After Putting up with the crap satnav and no Bluetooth

Ive fitted a parrot smart unit within the dash with a bit of cutting around the facia

 

I had to remove the amp in the back , and make some connections with the wires

coming to it from the front also fitted a high pass over for the 4 tweeters in the system

 

It all works fine BUT HERES THE ISSUE

 

the FM reception is low I've connected the aerial to the unit and checked the connections to the rear window

Is there any power amp within the aerial run , that was fed by a live wire from the old unit

 

any help on this matter would be good

 

cheers dave

Hi, check the link bellow.

Do you get power to the antenna, it should have 12v , I assume that it was getting power from the amp( not sure though).

Hope it helps.

Hi, then the easiest way would be to fit a digital antenna.

Or for further investigation, try disconnecting the radio and check if you still get power to the antenna, then disconnect the connections you made to bypass the amplifier (if you can do it one by one and check every time the power to the antenna is even better) and see if you still have power to it. In the bellow link you should see a picture with a radio c1 socket, pin number 5 is for antenna, is that connected to a pin(from the radio) that relates to "turning the antenna on". Plus make sure the wire is positive or negative.

Take a look at the link bellow, it shows an antenna amplifier with short leads, so I assume it is near the radio enclosure.

Also check this link too, try grounding the radio, from the radio case to the body),

From the plug diagrams ( thank you ) its got the 22 pin what sends the signal to the amp

from the ebay link the amp must be in the rear panel at the top near the plug leads

prob then powered buy the amp

I can use the signal lead from the old circuit to run a live down from the aux live wire so wont flatten batt

Quick update

 

the amp is in the rear headlining , there is a single fine black power wire to it

there is no wire like this from the radio plug or the plugs to the amp

 

so there prob is a relay ill rewire it from the aux lead

 

thanks for all your help
