Conclusion: These are very good and loud 6.5 components. I've followed Jbl products which they are very durable and have good quality. I recommend these for good highs and average lows. These are priced very affordable and are my substitutes to Focal 6.75 165's.
Conclusion: As everyone says... These are powerhouses that have tons of low mid bass! I love them. The tweets aren't shrill or harsh like a lot of other brands. I have 75 watts rms running to them off an alpine mrp300 and they just crank! Possibly my favorite components I have had. If not I would tie them with my last kappa set. Great value for the low price! I would def. buy these again.
Conclusion: Best 99 bucks i ever spent, loud clear and stage perfectly, way to go jbl. I've been in car audio for over 2 decades, almost owned everything, diamond rockford focal, these jbl's get the job done...very pleased.
Conclusion: Replaced some infinity components that were weak in the midbass. Got a great deal on the jbls. Sound much better in the low end and midbass. Highs are decent but couldnt say if i 100% like them or not. I am still using the infinity crossover.

Conclusion: These speakers sound great in my Saab 93. The mid-woofers JUST fit to the point where my installer shaved a little bit off the back of the door grille to ensure they didn't hit when they're moving. They have a lot of mid, I mean, when a chick hits the lower notes it's almost too much but that can be sorted out with an eq/x-over. I'm powering with Pioneer GM-D8604 and they sounds great. One of the speakers where blown and Sonic Electronix returned it.
Excerpt: Just bought my second set of P660c 4 6 inch drivers and 4 tweeters added concert sound to my 2500HD Diesel. Excellent sound when driven by the GT05ez midrange was great clear along with the tweeters great highs love them all
Conclusion: Ok first off I have never liked Jbl before. Upon install immediately blew my mind I was laughing and crying. I am so confused these aren't even broken in and are completely insane. Ok first the biggest thing is the low end insane low end like subs so if you want usut mid bass look else wear like focal. These have insane low end bass it's complete insane I've heard tons and tons of mids and components nothing comes close. Next is volume insanely loud just nuts.
Excerpt: Insane low end insane low end like subs pound hard and low. I'm still in shock this is insane. Incredibly loud and clean. There is no flaw none buy these right now I'm telling you it's the worst choice you'll ever make if you don't buy these buy them right now forget sets that cost ten times more no need buy these I'm still in tears from them.
