rear deck speakers shaker 500

I searched around and didn't see this in a thread.

'11 GT with shaker 500

I noticed the cheap rear deck speakers seem to attached to the deck with no internal ( cabin) openings . The deck doesn't seem to have any evidence of a port/grill cloth , just a solid piece .. seems odd..

SO is Ford relying on the resonance of the decklid ? or am I missing something?

I plan on upgrading , just curious as to whether ported rear deck speaker openings is a normal mod

Thanks in advance

I crawled back there over the weekend . sound comes out fine however it's rigged .. I'm sure a decent set of speakers will be an improvement and the access is easy .

Access is far from easy. You have to disassemble half the interior to get to them and then have lots of patience backing the torx screws out next to the window.
