300ZXSC300

I'm in need of help. I'm stripping my entire back seats, back rest, and trunk to put Dynamat on those area. I have about $800 dollars worth of it and starting it this coming weekend.

I need to know what the OEM Subwoofer Specifications are. All I know is it's a 8''.

I'm looking for a replacement Subwoofer either in that same location of the size 8'', or a standalone Subwoofer in the rear trunk. Haven't yet got to that point yet.

Also, what speakers will fit the rear of the SC300?

5 1/4'' is the OEM size for the rear speaker. Any chance 6.5'' will fit?

Can a 10'' Shallow Mount Subwoofer fit in the OEM 8'' Subwoofer area?
