A few questions for you all.

What is the best replacement deck interface on the market? Soundgate, PAC or maybe someone I haven't heard of yet? Which one do you all suggest I use? I want to keep my Onstar, Bose, chimes, and the XM Radio if possiable.

What size sub is in my console? Is there only one sub?

Is there a way to tweak more bass out of the factory amp?

Both Soundgate & PAC are great interface companies to deal with. The other company that does changer interface & XM radio is BlitzSafe. The OEM system is limited to what it can do and can not be tweaked to get more out of it. If you want better performance from the sound system, you'll need to replace components of it with aftermarket equipment. If it's like the other Bose sub woofer's then it's a 9" flat free air sub.

There is no way to keep your factory XM if your remove the factory radio.
There is a single dual voice coil subwoofer in the center console, i think it is a 5.25" subwoofer. Replacing the head unit alone is not going to give you better sound or more bass.
