I ended up using the CD changer bracket; fastened the amp to it using strong double sided tape (the sort used to hang bathroom mirrors on tile walls) and it worked out great.

I first intended to use the CD changer bracket but I do not feel it is up to the task of supporting the much heavier amp.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I'm adding a new amp to my 03 986. I have removed the old amp and CD changer and the new amp will go where the CD changer used to be. I first intended to use the CD changer bracket but I do not feel it is up to the task of supporting the much heavier amp. So I am now looking at mounting it directly to the bulkhead/firewall with an MDF mounting plate in between. Question is how to affix the mounting plate to the bulkhead. Is it safe to screw it directly to the metal, or is there anything behind the CD changer location that can be damaged? Where exactly is the gas tank?

POST 2Original post

Quotes source post: 303353

Directly behind that bulkhead...............

POST 3 / ORIGINAL POSTEROriginal post

Quotes source post: 303357

Are you kidding? Gas tank directly below the battery, right in front of the passenger (my car is RHD)??? In between the crumple zone and the cabin? I really hope I am misunderstanding you...

POST 4Original post

No, you are understanding me correctly, and that is exactly where the tank is……

POST 5 / ORIGINAL POSTEROriginal post

Oh dear. Looks like I'll have to use the changer bracket. Or maybe the 2 bolts which held the bracket can be used. I realize it's not the easiest to find a place for the tank in a mid engined car but still...

POST 6Original post

Well, as the engine and trans are in the rear, it had to be behind the front bumper, on wheels being towed behind the car, or where it is.

POST 7Original post

You still might be ok fixing to the bulkhead as the tank is fairly low slung And quite a strange shape! Measure twice cut once.

POST 8 / ORIGINAL POSTEROriginal post

Okay, I am looking at four screws, two at the extreme top of the bulkhead and two 200 mm further down. From your pictures I do not believe the tank is located so high.

POST 9Original post

I would have thought that Mr Porsche would have wanted to keep the centre (center) of gravity as low as possible.

POST 10Original post

Quotes source post: 303390

The opening in the top of the fuel tank pictured is directly beneath the battery..........

POST 11Original post

Use silicon or some other adhesive to mount a piece of MDF to the firewall. Then screw the amp to the MDF. No worries on whether you may or may not puncture the gas tank.

POST 12 / ORIGINAL POSTEROriginal post

Quotes source post: 303404

That's a great suggestion, why didn't I think of that? I have lots of 6 mm marine plywood lying around. Assuming there is space to insert a sheet between the carpet and the bulkhead I'll use the two CD changer bolts and my trusty PL400 adhesive to affix it. Voilá, invisible mounting plate.

POST 13Original post

Using plexiglass might be easier and it would "flex" a little. The bracket doesn't have much force on it. I managed to fit my larger amp over the existing bracket with only one "modification piece" made out of plexiglass. It tightened down nicely. Not much weight either.

POST 14 / ORIGINAL POSTEROriginal post

I ended up using the CD changer bracket; fastened the amp to it using strong double sided tape (the sort used to hang bathroom mirrors on tile walls) and it worked out great. Unfortunately one of the two threaded nuts in the bulkhead fell down - impossible to retrieve or replace - so the bracket is now held by just one bolt until I figure out a solution.
