ZK-3002 Amplifier Board 300W Dual Channel,600W Mono TPA3255 Chip Pure Rear Stage Power Amplifier Board

Project: home made Bass guitar amp!I started the project with a similar 160 watt amp board available on Amazon. That one was okay but not great quality. And easy to destroy because negative power isn’t negative speaker! Instant destruction!! Not sure on this unit.. but avoid if possible! This unit has much better soldering and components.Good:•plenty of power•quality construction•built in speaker pop protection circuitBad:•needs a good preamp•supply voltage is high, not as easy to find lying around
