great product for the money

Had horrible alternator noise. Ordered this product it helped eliminate 95 percent of the noise. The ground wires are a great add they helped eliminate more noise. Great product, great value. Would buy again

Works good even when used from a headphone jack

I had a significant amount of static when piping music from my laptop to an LCD TV (to use it as a remote monitor via its VGA & audio inputs). Without the Stinger, the static essentially ruined the sound of the music & was extremely distracting. With the stinger in the circuit, the static was almost completely gone, even though I was pushing the technology by using the laptop's 3.5 mm headphone output jack (it had no speaker jack per se). Now that I can listen to my stuff on the big screen without the static, I'm "ecstatic"! The Stinger also has the best quality I've seen in this kind of ground loop isolator.

Noise Reducer

This product reduces a lot of unwanted hiss, click and pop traveling through RCA audio lines. Great product but it's not magic, it only will reduce noise not make it go away completely.

Great difference

I was getting alot of the whine from the car electrical through my highs amp and i hooked 2 of these up one for the front and one the rear channel. I didnt have to hook the additional ground up and it cleared the sound right up and allowed my highs to sound a lot better nice and crystal clear.

Stinger SGN20

Excellent and does the job
No noise from the system

they look good

The male rca goes int the amp and the female rca is the lead from head unit. When i went to hook them up the decal on the top said opposite so i had to call co and they said the decal must be backwards which if they cant put a decal on right then what about the rest. But i didn't want to wait or hassle with return so here we are 4 months later and the work fine.
