I've ran some RTA for the speakers and looks like there's not much bass roll-off happening at all. The vehicle is also sending out full spectrum on all speakers.I do not have my I5 yet (hopefully in a month or two), so I am just collecting information and thinking about speaker and amplifier upgrade options. No factory supplied OEM crossovers outside of the head unit (e.g. in the doors) is my understanding.
Reports here are that some owners believe there is full spectrum on some of the speaker wires (e.g. because of blocking capacitors on tweeters). I am always concerned about some kind of filtering / shaping inside of an OEM head unit, but have no first hand information yet. I guess there should be a way to play some tones from 20 Hz to 20 kHz and to watch the corresponding signal amplitude at the various speaker wires.
Anyone run active yet?
Most of my parts are starting to come in and have been trying to understand the vehicle.
Currently installed a subwoofer for now.
Would like to try to run my own separate speaker cables.
