Review: Fit in my 02 TJ - sound good! - Fit great in the soundbar of my 2002 Jeep TJ. Sound great too
Review: For the money, they hit! - I have a 91 VDub Wolfsburg Jetta that I have been spicing up, reliving my youth. And last year I bought some 3.5 Rockville 3 ways. I didn't realize the Boss headunit(my father is a car dealer, he pulled it from a car and gave it me) I am using has a built in 300 watt Amp. The Rockville speakers were only 30 watts. I replaced them with these Boss speakers and also put in some 3.5 Boss Chaos, 140 watt. I hooked it all up with the Rockville 6x9s and wow what a difference! I am probably going to get some Boss 6x9s so I have it all Bossed out! I bought a 10 inch Rockville sub for the spare tire but I don't even think I'm going to hook it up. For the money, you can't go wrong with these speakers and the 3.25 Boss Chaos! I can't wait to drive my car to work tomorrow! Beastie Boys will rockin!!!
