If you are talking about the single supply TDA based version, it may be. The breadboard is not one of a best in the market but it's still a breadboard, we all know that they are not useful every time you need a good quality signal even in audio applications. However I moved every component to try making contact if there were missing ones and it was the same. By the way, the split supply version worked very well so I don't think it is a breadboard problem.
I designed a bridged TDA2030 amplifier and made the PCB, it sounded pretty good. I am going to make two separate bridges for the woofer and tweeter and cool it down with a PC cooler, it should keep the temperature below 100°C I think. Anyways I am planning to use a NTC to control the gain when the HS is near 120°C to avoid overheating. I know that the chip has a built in thermal turn off but I don't want it to stop sounding.
