500a2 crossover frequency
This is one of the amps with the crossover module inside the amp? You'll have to take off the round plastic cover and pull it out to see what it has in there. They are interchangeable and made several settings. Usually the were 90Hz if installed in 1 position and flipped over it was full range, you could get others to cross over your Tweets too. As I recall they had to have that module installed or it will send square waves and damage your speakers and maybe the amp.
