Check to see if there's a steering wheel control module from alpine for your vehicle.
Also, just use a mounting bracket to put the new HU in. Atleast the gap will be blocked off.
You are correct. If you tie into the back speakers you won't have independent control of the bass from the speakers and the subs. Turning up the bass would result in the speakers distorting.
I assumed you were using the OEM HU. If so then the way I suggested is the only way. If you use the alpine the just use the sub-pre-out for the sub amp
