DHC: How much space above gas tank?

[moss0031]

Hello all,

Long time lurker, first time poster. I was planning on installing some speakers in my rear deck of my 79 DHC (yes, they will be muffled by the tonneau when the top is down). How much clearance is there between the gas tank and this panel? I've tried to check the parts diagrams, but I couldn't find one that showed this very well. Just though i would ask before I start drilling.

Thanks!

Er, about 1/8 inch. The tank fits right up against the panel, with only a couple of rubber strips keeping it away from the metal.

Aren't you glad now that you asked first? [:D]

Mine are on the top of the shelf where there should be plenty of room.

6x9's will fit in the front doors but you have to heavily modify the door cards. i can here mine clearly with the top down at 70mph. ( I made my own door cards rather than cut the originals)

I should note that it is a pair of 6x9s that I'm looking to fit with a mounting depth of about 4 inches. Right now I'm considering some sort of wedge-shaped (naturally!) enclosure to fit above the panel. Probably something I'd have to build myself as I don't trust the amount of rear vision I'd have with these:

@stevie: That's not a bad idea, looks like there might be enough space to fit a decent sized speaker there. Only thing it could foul would be the seat when moved fully rearward (though in my case I have Miata/MX-5 seats so they are a bit thinner than the stock seats). Other place i was just looking at is the back panel immediately behind the rear deck (so they would mount vertically). However, I'm guessing that they wouldn't be able to protrude much from there without fouling the top/hood when lowered.

@peter: DHCs aren't lucky enough to have the parcel shelf.

@Red: Thanks! That's what i feared ... does the tank run the full width of the panel? Any chance I could squeeze them in on either side?

No room there, tank and mounting point for the seat belts being in the way ...

Thanks Beans, that is the exact picture I was looking for. I appreciate it.

Maybe I should just fit a fuel cell in the trunk!

I thank you also, Beans. I needed to see that too. Does everything below it have to be removed to get the tank in and out? I was about to check the Haynes book. [:)]

There have been plenty of threads on this forum in regard to removing/replacing the fuel tank that will provide useful tips on how to do the job unlike the Haynes book which is largely a waste of ink and paper.</font id="Comic Sans MS"></font id="size2">

You could always do what Orange Rag did to his car.





"They are from a late 90s Saturn s series 4dr. It is screwed on to the door panel from the back so I attach them the same way. You may need to put longer fastening clips on the bottom of your door panel so they secure to the door.(because of the heads of the screws or use flat head screws)
There is lots room for speakers so I upgraded mine. I think I paid $20.00(Canadian) for two door panels, than I had some spray vinyl dye and presdo! a cheap fix and my kind of budget."

I attached small speakers from Radio Shack under the top strut covers. That gave me sound from the back as well.

Funny but since I got the new engine in, I don't seem to turn the stereo on much.[}:)]

I have added a box with 8 Walmart speakers in series/parallel, across the shelf between the seat belt reels. The box is just big enough to hold the 4" speakers and provide enough space behind the speakers for them to operate properly.
I started out making a wedge shaped box. tapering down under the hoodsticks all the way to the back of the shelf. When I put the hood down, I found the hood would not go all the way down. The box needed trimming, so I marked it and cut it off, then sealed the back with another piece of plywood. I used some scrap 3/8" plywood I had lying around to build the box. I also used plywood to make interior partitions (baffles) separating the speakers, but put holes in them to allow air movement inside. The speakers were installed on the face of the box, then wired together in series/parallel to equal the 8 ohms needed for each side.
The speaker box makes good sound, is right behind your head where it doesn't need to be so loud, and clears the hood cover when it is installed. On mine, the inside snaps won't quite snap (the ones behind the seats) but I never snap those anyway. This method of using the smaller speakers apparently is used by Dolby, according to my brother Jim.

@Dan B: Sounds interesting and is the direction I am currently thinking. Happen to have any pics handy?

I've already enlarged the door panels to fit 6.5" speakers and installed tweeters in the dash. For the rear, I'm now considering making an enclosure out of fiberglass to fit both 6x9 speakers (angled back at 45 degrees or so, however they lay the flattest) behind the seats. If i put that in place instead of the existing trim panels (and with removing the rubber mat underneath) hopefully it won't obscure the rear view too much and still allow the top/hood to be fully stowed. Granted, there will be issues with the tonneau, but I'm not as concerned with that.

[Dan B]

Unfortunately, I left my camera at the office. If I remember to get it tomorrow I will take some pictures.
This design allows for full top stowage and the top cover or whatever you call it fits over it to where you cannot even tell the speakers are then when the top is down. If I take pictures you won't be able to see that because I have the hardtop on it now that the weather is cold. The top frame/hood sticks fits behind the speaker box.
