Sirius XM antenna

Hey guys,
I just installed a Sirius XM antenna (

$59 SXV300V1 Satellite Radio Vehicle Tuner - Add to Any SiriusXM-Ready Car Stereo

SXV300V1) on my 2nd gen with a new Kenwood head unit (

$520 DMX7706S 6.95" Digital Media Receiver w/Bluetooth, Apple CarPlay and Android Auto

DMX7706S), I ran the antenna through the third brake light above the bed and was wondering if need to seal it with some silicon or something so water doesn't get through.

 

Would definitely recommend unless you want to do rust repair later.

 

I would def seal that with some silicone, Did you even need to run it outside though? I thought it would be fine just ran to the back inner roof-liner

 

I didn’t honestly think of that, I could give that a whirl, I’d assume the signal would be just as strong.

 

I put the antenna behind the third brake light on the underside of the roof and drove to work this morning, its a fairly open drive with a few tall trees and overpasses. The signal for Sirius cut in and out quite a few times, more than it ever has, so I ordered a new light / gasket and will install that and use some DAP auto marine sealant and keep the antenna on the roof, it was worth a shot but had better signal with it on the exterior.

 

I know im a couple weeks late on this, but i ran mine through a hole in the firewall that was already there and added a rubber grommet. Ran the wire out under a piece of trim and then up the windshield line with a small amount of silicone and its on the front area of the roofline on the passenger side... Worth a shot if you havent already sealed yours up

 

I ended up running it out the third brake light above the bed and using a marine grade clear silicone, once it cured that silicon is rock hard and its been through a few storms already and no leaks
