Does anyone else notice that the subwoofer is fighting the front speakers? If you send the system a sine wave signal anywhere from 45 to 60Hz the total volume goes down when you turn the subwoofer up. Weird?!?! Perhaps it is the ANC? Is it wired out of phase? It looks like they may have gotten a bit heavy handed with EQ? It started with not hearing much bass out of the sub when playing music and then I started investigating. The subwoofer works but something seems really wrong with the overall setup? Overall sound is weak for what is in the car. Just wondering if anyone has made any progress with this system? I am tempted to flip the wiring to front speakers or sub as a test but the car is brand new. Phase checkers just seem to get confused with what was designed in. Given the integration, aftermarket radios/amps seem out of the question. I don't really need a SPL monster but some bass would be nice.
