I Just installed these speakers along with a hifonics 6406 amp, and polk mom mmc570's in the rear. These Speakers are absolutely unbeleiveable. The highs are incredible. The mid range punch is so outstanding as well, they really pack a hit. The low end is good, but not like other low end speakers, which is why i bought the momos in the rear. My entire system is one of the best i have ever heard without a subwoofer, definitely think about my combination because it cranks! Awesome sonic electronix thanks!
