This is a weird problem, and may be Integra-specific. My car has stock tweeters AND mids in the doors (and stock mids in the back). Looking at the wiring diagram, the wiring harness runs a single pair into each door, and then there is a capacitor matrix that forms a simple crossover of sorts to run the tweeters, which are daisy-chained off the mids. So in the dash you have four pairs of wires for front and rear, left and right, as you'd expect.

When I wired up my amp, I bought a wiring harness adaptor so I could easily plug into the stock harness behind the dash and not hack it all up. I ran four pairs of speaker wire up into the dash area and connected them appropriately to the four channels on the harness.

When I first put audio into the amp after getting everything going, I noticed that in the front, only the tweeters are working. I'm not getting any sound from the mids. The rear speakers work fine. This seems weird to me - if the tweeters are AFTER the mids in the circuit, everything should work, right? I've tried turning up the volume a fair amount from the head unit, thinking maybe I wasn't providing enough power to run both speakers in the doors, but that didn't help. I haven't tried fiddling with the gain on the amp - it didn't seem like that would make a difference if the head unit volume didn't.

Anyone have any other ideas about this? I'm stumped. Thanks!

Sounds to me like the woofers are blown, as you say the tweeters are just paralleled, [daisy-chained] off the mids, and the tweeters work, [so the 2ch of the amp wired to them must work] that only leaves the mids, they are blown or unplugged. 94
