[QUOTE="kouger, post: 8855511, member: 689597"] So from what I can tell, the driver and the tweeter are connected together. The cap is inline with the tweeter. The cap has a marking on it 3.3 uF. 63WV When I put my meter on across the cap I get 8 ohms When I test across the tweeter connectors I get I get 6.2 ohms When I test across the driver / cone I get 2 ohms When I test across the pins for the speaker wires I get 2 ohms Now I just bought the JBL GX328. This is the spec from their website: Power Handling: 25Wrms, 75W Peak Frequency Response: 90Hz – 21kHz Impedance: 2.3 ohms Sensitivity (@ 2.83V/m): 89dB When I test across the pins for the speaker wires I get 2.4 ohms. There is a cap on the JBL GX328 with the marking of 3.9 uF. 5 0 V. One side of the cap is connected to the smaller of the two pins and the other is running under the sticker on the magnet and goes inside somewhere - can't see it. So I connected up the GX328's and I did notice that the volume is slightly lower on the GX328 than the original speakers. The other thing that was a big difference is that the GX328's have more bass and what seems to me like less mid. The high pitch sounds (like cymbals of a drum) are much clearer and more prevalent. The original speakers seem to have much more mid than the GX328 - could this be because of the capacitors. Would removing the capacitor from the GX328 cause any damage to the speaker - or swapping them with the original speakers capacitors make any difference. I would prefer to get more mids out of the new GX328 - I don't care if there is more base from them as it seems sound better in the car - just not crazy about the low mids. One thing I am happy about is that there is no distortion when a call comes in. Oh, I also bought the JBL GX428 and will probably swap that out with the center one. GX428 4" coaxial car audio loudspeaker Power Handling: 35Wrms, 105W Peak Frequency Response: 75Hz – 21kHz Impedance: 2.3 ohms Sensitivity (@ 2.83V/m): 90dB Any idea what the cap on the GX328's is for? Thanks for your help. Thanks again for your help. [/QUOTE]
