Hi everybody. i just wanted to share my sub replacement build. Apparently Image dynamics makes something that can be used in IB set up. Moreover, IDQ v.3 and IDMAX v.3 have a little bigger cut out diameter than standart 10" subs. I think they are 9.6". Stock Pioneer sub is irregular and the rear deck hole will leave extra space around the 9 1/4 sub. So, if you want increased SD aka surface area nearly of a 12 inch sub in your GS you can use ID subs. Just make sure you feed half of the recommended RMS for your new sub and put dynamat on the rear deck ( top and bottom to eliminate rattles).
