Cowboy, If I can remember correctly from my '98 TJ it had two 4x6's in the front dash and two 5 1/4's in the sound bar. Like JMA said, it is hard to go wrong with Infinity. Kappa's are the high dollar Infinity's while the Reference series is a little more friendly on the wallet. I'm running 6 Infinity Reference speakers with a Infinity Kappa Perfect Component 10" sub. Boy does that sub hit hard. The key to good clean loud speakers is an amp. You want your speakers to sound real good? Power them up.
