My experience

Bought this for my speakers but got told it wasn't need because my speakers aren't as loud lol. I'm a beginner so I just bought this cause I got told . I do have cousins that do use this though for their louder and much bigger speakers. Highly recommend if you have big speakers or subwoofers
