they are now hooked up w/o any crossover, just my hu sending rear speaker signals to my amp. they knock hard for 6.5", i put them into my rear deck, and when I fade the music all to the rear, they make my rearview shake pretty good. also slightly shake my seats. a very good midbass driver.
i've heard morel makes good tweeters, but i havent heard any personally. what about building your own crossovers? has anyone around here done that? is it tough for one to build a high quality crossover or do you just need to buy high quality caps and coils?
