Hey guys, so I originally posted this in the 5th gen forum and I believe it was moved here. I thought it was the huge magnet in my new sub that was messing with my radio reception but it turns out its my aftermarket amplifier. It is unbelievable how day and night the effect is. I have a switch that I can use to turn my amp on and off from the drivers seat. If its off I can enjoy 10+ FM stations if its on I get 1 station and even that station comes in poorly. The second I turn the amp on the stations that were coming in perfectly clearly go completly static, and the second I turn it off they come in perfectly clear again.. talk about friggen interference. Well this is one of those things I didnt see coming. I like listening to radio.. its really all I ever listen to so this is more of a problem for me than most. I tried moving the amp into the back seat but it didnt help. I am hoping that maybe the combination of an external antenna, and a thin metal box around the amp might cut down on the interference but as of right now the radio is useless with the amp on. If anyone has found a solution to this or knows of a way to block the interference it would be creatly appreciated. I know a lead shield would do it but I dont know how I feel about 50+ lb in my trunk.

 

Could be the power supply of the amplifier causing RF interference on the reception. But usually this is more noticable on the AM stations than anything. Possibly the switched lead that you're using to turn the amp on is pulling current from something else that needs that current to work, like a factory antenna amplifier? Disconnect the switched lead that you're using and set that aside. Run a jumper lead from the B+ terminal on your amp to the remote turn on terminal on the amp to see if it still loses reception. Don't always run it like that as it will cause your amp to never shut down. Give that a try.

 

I disconnected all the signal cables from the amp and just left it connected to the battery and the ground, the amp was in no way connected to the stereo system, it was just sitting in my trunk and even when it was in no way connected to my stereo system the second it went on the radio went dead every time. So it is deff interference but I cant imagine what in the amp would cause THIS much interference.

 

Like I said, it could be the power supply of the amplifier. Must be oscillating at just the right frequency to mess things up for you. I guess the next option might be to borrow a buddy's amp to see if it does the same thing?

 

What kind of amp is it ? If its some cheapy am then i have to say im not surprised.

 

Its a hifonics tx1005d
