INSTALL
I first pulled the seats, style bar, carpet and shouldertbelt covers.
The parcel shelf was next.
You can see once it's removed the area where the subs will sit. Then the first
of many many fitment checks.
I marked the sub outer frame while in the car, then made a template for the cutout.
Some more triple checking fitment.
Then placed the shelf on a cardboard box for support. It made it a lot easier when I went to cut it.
Cutouts done and back for another fitment check.
Now into the car for a clearance check. Note the drivers side cutout: the gas tank is in the way.
Here the corner of the gas tank has been massaged with a ten pound sledge
hammer (lightly).
Then some underside views to check clearances.
More clearance and fitment checks. Then cutout the backing, rubber and carpet.
Everything ready for bolt in. I made some foam gasket and used some stainless bolts and self lockin nuts.
All bolted together and ready for install. I had to drill clearance holes
where the bolts go.
All finished with the stylebar back in place.
A couple last shots of the install done and the amp mounted in the trunk.
The amp box will have a plexiglass top with several vent holes.
You may have noticed it's sitting in the trunk well. It fit perfect there.
