Subwoofer pooping

[Kingmobileaudio]

I have a TM-V71a installed and never had a problem till I went on vacation now.
It makes a pop when the mic is keyed up on 2m but not on 70cm. Most noticeable on high power

I have the rca's away from the coax. Heck it even does it without the rca's plug in<<< witch is why I am lost why this is doing this?

RF gets into the circuitry of the sub.. I had one on my computer that would do that all the time, and I run APRS 24/7/365. And 80m would drive it absolutely batsheet crazy.. Got rid of the sub..

Toroids may help at both ends of the RCA cable.. Good luck..

You might need a litter box for it.

Oh, wait, it's a subWOOFer. I guess that means you need to walk it now and then.

LOL.

I had that same problem when I had a tm-v7a installed in my 2001 Grand Am. I tried a few things, including finding a better ground spot. I never was able to solve the issue.

It's just wired how never happened till now. Only thing I can think of doing is a new amp or coax

My computer speakers did this on VHF as well.


My solution: replace speakers.


Picked up a set of speakers that specifically advertised as shielded for RF.


Not so sure about subs in a vehicle though.

Well, there's your problem right there! If it's wired, why not try disconnecting the subwoofer from the radio's RF output? There's a reason why the radio is also known as the "wireless".

(Couldn't resist.)
