THe first car I saw with front-facing rear speakers was Mary Diaz's car in Atlanta - a base coupe.

The system was so much better sounding than factory. BY FAR.

 

I am assuming that you cut a hole in the carpet that matched the inner diameter of the fabricated mount and then drilled through the carpet for the mounting screws for the woofer speaker frame.

Then you mounted the speaker cover on top of the mounted speaker.

So, if additional maintenance behind the carpet is required, the midrange woofer needs to be removed before the carpet is pulled away from the back.

 

100% correct

the only item not installed are covers over the speakers.

they’re behind the seat backs so I didn’t bother.

I did discover one downside.
Another full day on the highway, rear speakers were turned up and thumping along.

Couldn’t figure out why I needed to stop every 90 minutes for. Rest stop break. Then it hit me. The subs were Eviscerating my kidneys.

but the sound was great.

 

Cool! Does not sound good for old guys like me.
