I have two Alpine Type R's in the mail from ikesound.com. Magnolia Hi-Fi has pretty much convinced me that the best amp to power them (that's in my price-range) is a 500W Alpine mono-block amp. I am most impressed by its sound and push on the subs. However, it's $500 retail. Do you think that would be a good buy? What else would be a good buy that would offer me good SQ and SPL in a decent blend that's $500 or less? I appreciate all comments, except those made by player haters.
