[QUOTE="AWD PSI, post: 7063666, member: 625722"] The polks are pretty well broken in now and the bass has improved noticeably, nothing earth shattering but impressive I think from 4 6.5's, vibrates my side mirrors and that's more than the stockers could do. The rear coaxial speakers put out more than the front components which brings me to my question: How can I find out what my front components are crossed over at? I'm assuming they are crossed over because the bass output is lower than the rear coax's. Could that be a function of my doors being mostly sealed? The crossover unit only has tweeter attenuation controls, -3, 0,+3 and the specs on my comp set say range is 35Hz-23kHz and the coax specs are almost identical at 35Hz-22kHz but they hit harder. The manual and polk's website offer no insight. The amp gains and xover settings are the same and haven't been set yet. The only thing I've done was add a touch of bass through the eq in the headunit. Maybe it boosts the rear a little bit more? I did the phase/polarity check by fading front to back and left to right. On all speakers bass was weakest on one speaker and improved when faded back to the middle. Fading front to rear, bass was stronger in just the rear as compared to just the front, but was strongest when the fader came back to the middle. I'm currently reading through the gain setting sticky and speaker FAQ thread so I can start tuning and kind of know what I'm doing. I found this entry in the Speaker FAQs to use as a rough guide. Will this get me close? Suggestions appreciated.
