in this video I will show you how to make dc 12 v powerful bass audio amplifier using TDA1558Q 4 cannel amplifier IC. in this circuit I used this as 2 channel bridge mode sot the out put is 22W X 2 and need dc 12V 3-5 A power supply or car battery. Use large heat sink to prevent from over heating.
PCB layout is in the link bellow.
