After reading rave reviews on the Harley Boom Audio speakers I decided to buy a set. The reviews were on the money with great sound, less volume needed and great appearance. The discover was this. I never thought to even look at the Ohms rating on these and now that I have decided to maybe replace my head unit I find that all of the head units I like are 4 ohms and do not recommend using 2 ohm speakers because of heat to the head unit amp. Is there any way around this with out changing the speakers. I really like them.
