Help!! Speaker noise (humm) with outside flood lights on

[gunner_bob]

Hello everyone!

I'm new to the FR forum, and appreciate all recommendations to help solve my speaker noise dilema. I own a 2010 FR Shockwave 29SALX with Clarion Stereo System with AMP (inside & outside speakers). While listening to the stereo with the (2) outside lights on, I hear a constant "buzz" or "humm" in the speakers. When I turn off the outside lights, the noise goes away and the speakers sound perfect. Possible ground? If so, where should I check for proper grounding? Also, does anyone have an electrical diagram of my FR Shockwave?
Thanks in advance for your replies.

Cheers!
Bob

I had a similar problem with a Vizio sound bar. I purchased a ground loop isolator for the speaker wires on eBay for about $8.00 and it solved the problem.

Where did you hook up the ground loop isolator?

Mine uses RCA style plugs and it just plugs into the speaker wires on one side and then the speakers on the other.
