Hi all how are you. I hope u are fine. Just a quick question. The driver of my hartke b30 is damaged and i have another one of the same size but is 200 watts and 4 ohms. The original driver is 30 watts and 8 ohms. Will the driver with 4 ohms hurt the amp? Will the output of the amp be like 60 watts instead of 30 watts because of the new driver 4 ohms?
