Hi, I am in the process of upgrading my 6 1/2" front speakers and would like to get unbiased input from people that know alot more about car audio than I do. I have norrowed down my choices to: JBL P660C 90W continuous 94dB (2.83V @ 1m) 45Hz – 23kHz 2 ohms JL Audio C5 650 75 Watts continuos 89.5 dB @ 1W/1m 48 Hz - 25 KHz (± 3 dB) 4 ohms Polk Audio MM6501 125 w continuos 94 dB 40-25kHz 2.7 ohms I will be driving my fronts with an amp rated at 90w x 2 @ 4 ohms 160W x 2 @ 2 ohms The rear channels of the amp are briged to drive a 12" sub. I am a classic rocker so maximizing volume and having good sound quality is important. Does anyone have experience with any of these speaker that they can share? There's not a car audio shop near that has any of these speakers available for display which makes this a tougher decision.
