E70 Premium Sound upgrade
I have the Premium Sound (Professional) in my 2012 X5. I am considering swapping out the subs for more bass. Has anyone had any luck with this? The Premium Sound already has great bass, but it is a little lacking in the low low end. I am not sure if this can be solved by new subs to replace the stock under the seat, or if I would have to increase the watts of the amp as well. Any thoughts? I may just add another sub with the logic 7 harness....just curious if there is a decent upgrade for the subs that are in the car already.
