Okay that make sense. The door speaker work with the dash and tweet disconnected, but the dash speaker will not get power unless the tweeter is also connected. This is why It seems to be a different circuit.
It was just a simple replacement of the factory "3.5" (cone is same size as my
3" dayton). Sound is more crisp and clear while slightly louder than stock, maybe. Sound pretty balanced to my ear. Wil have to try with the tweeters bypassed ala soundman98.
3 parameters for choosing this speaker. Power handling (30wrms), flat response and good off axis response, then cost. For $12 a speaker, I'm pretty surprised. Or maybe the stock just really suck.
Edit: @
LimitedSlip I just got done "auditioning" the sound with and without the tweeter. Did this by keeping the tweeter in the passenger side channel and bypassing it in the driver side. Here what I found:
1. The side with the tweeter bypass plays a bit louder. No surprise.
2. Sampling some smooth k-pop R&B styling of DEAN and his broad vocal range. The tweeter channel sounded more 'complex'? here was more definition like in a larger room or concert hall ( this is with all of the bass boost turned off or into the min setting and rear channels completely off. ).
The no tweeter side sounded more natural, like he is sitting right in font of me singing than in a concert hall. The tweeter side sounded "larger?" The no tweeter side I feel lacked some high frequency response. With a different dash speaker with better off axis high end response would probably do better than the one I have without a tweeter.
