Shark Audio motorcycle problems?

I have a 250w shark audio sound system
For motorcycles and I had it for 2 years almost and I recently moved it from. My suzuki to my Honda cuz the suzuki wasn't operational and It worked perfectly but a day ago just decided to have a sort of glitch.makes this weird distortion noise whenever I use the AUX mode but radio works fine
I've been playing my music loud but don't know what's wrong?

Possibly a bad ground connection

  • How much to install an audio system in my car? My car is a 2001 Honda Civic DX Coupe. I want to replace the stereo and also get subs and an amp. I may also need a sub box. Also, I'm new to audio systems and subs so I'm not sure if I should get a pair of 10's, 12's or just a single 15. My budget is around $250-$350 if that's possible. What would you guys recommend?
  • Honda Civic Audio Problem? The Honda is a Civic 2003, coupe. The radio appears to be working, but there's no sound coming out of the speakers. Sometimes the speakers come online, and makes a loud constant noise, with a little sound from a nearby radio station. The system is stock, original. The security code was validated. Is it just a loose connection, or is it something with the speakers/amp?
