My boss instructed me to install their power amplifiers and bass speakers. It took me a lot of time to finally get it done. Thank you for your guidance. The effect was very good and I was very satisfied.
I bought Harman Catton's bass horn before, and I felt bass or almost felt it. I bought their power amplifier through the introduction of my boss. The two were matched together, and the effect was immediately good. Now there is a very good bass.
