My 2009 CX-7 has the Bose system from the factory (9"s in front doors, 3"s on the dash, no subwoofer) and I'm wondering what my options are for aftermarket upgrades? I'd like to keep the factory headunit to retain the trip computer, dash clock and steering wheel controls along with the general OEM aesthetics.
From what I understand the Audison Bit One can accept balanced line or speaker level inputs, is this a viable alternative to replacing the headunit? If so, are would it would work from the HU pre-outs before the factory amp? Or would it be best to run it on the speaker level outputs of the factory amp? And how would the inbuilt factory amp crossovers come into play?
From what I understand there is a bit of sound processing done in the factory amp... center dash channel mono, crossover points and possibly even the actual volume control. I have attached the system wiring diagram if that helps.
Just so you know where I'm going with all this, the long term plan is an active 3-way front stage. Dyn, Cresendo or HATs (yet to audition to decide). Probably running off a couple of Arc 300.4 amps. Sub is undecided at this point too, I'll decide after the fronts are in. I was originally thinking about putting in a double-din HU with integrated navi / bluetooth etc, but I'd prefer not to if I can get away with it.
I'm more than open to thoughts and opinions, it would be much appreciated.
And here's the wiring diagram.
