I have 2012 IS-F with ML. The stock Subwoofer was removed and a JL 10W7 + XD600/1 + LC2i was installed. I am still not satisfied with the sound and consider upgrading the speakers.

But before I do that.. I need to know if I should get an Audison Bit Ten or One? I know the One has the channel output. I have a concern that the Bit Ten does not have enough output for the all the speakers and sub in the car.

 

Did you ever get the bit one or ten. ? From what little I know about the 10, the one would be too much for your system unless u plan on upgrading and adding more amplified channels

 

I never upgraded... but now considering the AP8.9 bit .. with built in amp.. I don't need SPL but SQ.

 

If your running speakers with crossovers then the bit ten will do jus fine. If your running active then the bit one.
