Great product. Don't bother with the $125 blue jeans one, this one works exactly the same for 1/4 the price. I have a very noisy rca line due to my receiver being connected to my PC's graphics card via hdmi as well as splitting a single subwoofer out 4 times with cheap Chinese adapters and running it all through a random rca volume knob (which was producing feedback itself, the hum and "tapping" of the sub drivers was louder when the knob was at zero and was quieter around midway then really loud at max. When I would play a game and thus be using the graphics card the feedback on my 18" driver was insane I had to turn it off. Anyway I added this into the start of the system and 95% of all noise is gone and what's left can only be heard if you put your head right inside the driver cone so for all intents and purposes they're silent as I can't hear anything from the seat. I sleep in the same room and have been able to leave them on now when sleeping as even with all the amp etc turned off they were still getting noise from other appliances plugged in. Anyway great product, massive upgrade to my system for $35. Going to buy a small distribution amplifier to clean up and boost the signal which should further improve he quality. One last thing, prior to using this whenever I switched my heater on or off all the subs would pop as there was some electrical disturbance. Now this doesn't happen anymoreRead full review
