I have Halo Extreme with upgrade crossover and Seas millennium tweeters. They sound fantastic. Crystal clear and great mid range. Large Soundstage and perfect center. I'm using 2 Prima Luna Evo 400 amps to run the tweeters and mids. 2PS Audio 1200m monoblocks running the 8 12in woofers. Soon I will be changing the woofers to more efficient and powerful ones. The stock are a little weak. Overall money well spent.
