    Sir Giovanni, saan po ang shop niyo? Ipapaayos ko sana Kevler ampli ko. Hindi pantay ang volume niya at kahit naka-off na ang volume control, may sound pa rin. Pag dahan-dahan mong ilalakas, di siya lumalakas pero may point na biglang lalakas. Ang unang lalakas yung left channel. Hindi sumasabay ang right channel kaya pag lumakas na ang right, hindi na pantay ang volume. Mas malakas ang left kaysa right. Volume control ba ang may diprensiya? Pls reply back.
