Feedback noise

Great price, looks nice, works but it gives off some kind of feedback noise. This was supposed to be just to add some tweeters to my system, after wiring it all up and powered it on I noticed the noise, went thru all my wiring, checked all my grounds and noise didn’t go away. Finally I pulled the rca to the and and the noise disappeared. So I swapped out the amp with a larger JL amp I have using the same wiring and no noise. Wish I had tested it before installing, I ran all the wires and cut to length, waste of wire, money and time. I do not recommend this product.
