Stock Tweeters with Aftermarket Speakers?

Hi Guys

I originally had a set of JL 3 way components, the stock tweeters were disconnected. One of the comp. tweeters recently burned out, and since the kicks i built were a little ghetto, i decided to ditch the comp. all together.

Anyway, I now have Polk DB650 (coaxials) on all four doors, I needed the upper staging so I decided to reconnect the stock tweeters (stock wiring).

Is this OK, ohms wise? The coax are 4 ohm and the stock tweets are 4 ohms, does anybody know the final ohms, 8 or 2? I dont know if they're wired in series or parrallel.

Thanks in advance.

vpkb,
Without digging thru my and others old links on this topic, I believe the speakers are wired in Parallel. this would yield a 2 Ohm load, which is, as I recall the load with the stock speakers.

If you use stock wiring, the factory tweeters and the door speakers will be wired in parallel.

In a normal two-way system with crossovers on both the tweeter and woofer, two 4 ohm speakers do NOT create a 2 ohm load, even when the speakers are connected in parallel. That's because the crossovers make each speaker's impedance very high in the frequency range above or below the cutoff frequency. Example: crossover at 2500hz; woofer is 4 ohms below 2500hz, but much higher above 2500hz; tweeter is 4 ohms above 2500hz but much higher below 2500hz.

Note that that no speaker has constant impedance at all frequencies. Most "woofers" have a rising impedance at higher frequencies. A coax or component speaker with a crossover is a different situation. At high frequencies the impedance of the tweeter is probably the deciding factor.

I don't believe Honda had a low pass filter on the factory door speakers - they were run full range. We don't know the impedance of the factory speaker in the range of the tweeter, but I bet it rises well above 8 ohms in the range of the tweeter.

Lotta words I know.....I think you are taking some risk by connecting the factory tweeter in parallel with your new speakers. If your new speakers are 4ohms in the frequency range of the tweeter and if the factory tweeter is 4 ohms, your amplifier will see a 2 ohm load.
