I just got JL TRxi's put in my Jeep Grand Cherokee. For their base line of speakers, they are absolutely amazing. 6x9's in front, 6 1/2's in the rear doors, 3 1/2's in the dash. All six speakers cost me $280 installed. I added a JL 12" sub in a custom-built enclosure for another $350. I've had nothing but high end components in the past and never had a system that sounded better. I may never buy "expensive" speakers again. I had to be talked into getting these "lower end" coaxials installed by my installer who's put in $8k systems in for me in the past. I couldn't believe my ears. They're perfectly balanced with crystal clear highs (not harsh), balanced mids, and ample bass. Plus they're much more efficient than components. I recommend running good clean power to them for maximum effect. I'm running an old set of phoenix gold x series through them and they sound superb. A 500 watt mono and a 75x4 watt amp. An Avic Z1 is the brains of the system. I can listen to them at loud volumes for hours without getting fatigued. Don't waste your money on components. Trust me, with today's techonology and media formats, these are the way to go.
