I am going to swap out my bose system with something a bit more up to date and I am trying to find out if anyone has done a stealth sub install in their C4 (1984 specifically) in those storage compartments behind the seats.

I am reasonably sure that there is enough enclosure space with some of these new "small space subs" but I am wondering if anyone has some pictures of a similar install to give me an idea of how it looks and/or how they did it.

 

I put a 10" back there and love it. Don't have the time to write it all up right now, but the inner lining was pulled out, two wooden cross braces added (some strong butt epoxy hold in place, silicone around), rubberized undercoating all of it, silicone on EVERY gap, a 3/4" piece of wood was cut to fit an inch or so under the plastic of the door so the speaker wont hit the door, 6 or 7 screws are there to keep the wood in place, and silicone all along the edges of the wood and screws. After all that, I believe around 8 holes were cut into the back side of the door to help sound when it is closed, but it still sounds better with the door open.

I'll try to get some pics soon, but can't right now, too tired.

Forgot, polyfill was added in there, and I didn't take pics as the work progressed, which I should have in hindsight.

Here are some pics

 

very :cool: , that definately qualifies as stealth. How much internal air volume did you end up with after modification to the storage compartment?

 

I'm not really sure, we didn't measure. It was at least 1 cu ft though. Not exactly the best way to build a sub box, but I'm extremely happy with it for what I wanted.

If anyone knows how I can hide the 2 amps in the back like the sub, let me know! Same with the 6 disk. Right now the plan is just to build a bottomless floor to sit over them

VERY NICE INSTALL! I am looking to do the same...do you have any pics of it during install? How does it sound? I like the way my 6x9's sound now...but just need a little more "kick"....Great job!

 

Love the install... that is choice!

I was under the impression that you had two subs from your first message, but I am glad to see it is just a single. That is what I want to do when the snow flies up here.

I can see that you drilled a few holes in the bottom of the door covering the sub, I am guessing this is to let more of the bass into the cabin. If that is correct, did you try it without the holes first and were unsitisfied, or did you just do it all at once since you were already making the mess?

Also, in my 84 I have a larger chamber under the tray that sits in the top half of the storage compartment. (in that larger 'under-bin' they have the torx tool to remove the top) You mentioned that you did "a lot" of sealing work during your install. Is that because of modifications you made to that lower bin, or because later vettes don't have a similar storage system?

I appreciate the pix and they do give me a good idea of what I am going to have to do. I hope that you figure out something cool for the install of your amps and cd changer. I would love to see some progress shots of that.

Like I said, this winter I am going to do a similar install, I will be sure to document my successes and failures for you all to laugh at!

If the pix got attached to this I am sorry, I'm new to this CF.com business...

 

I measured mine... it comes in at just UNDER 1 cf.

like .99 and change. your average 10" requires about .70, so there is enough room to work.

 

No, I wish I had my camera at the time, but I left it at my house. My friend and I did the work at his. There is plenty kick for me, but I wasn't looking for something to shake the car apart, just some thump. Right now, I haven't adjusted the amps and head unit to make the stereo sound its best (I'm too lazy right now :lol: ), but it sounds pretty darn good to me, a lot better than the Bose.

 

We drilled the holes before listening to it, since the doors were already out of the car. Right now, the door will rattle if I turn up the volume, and there is a noticable difference with the door down, and up.

There was just a small bin that wasn't held down by any screws, it just pulls up to access the bottom. I'm not really sure what yours looks like :confused:
The side of the cubby closest to the seat back had some pretty large gaps around it, especially at the corners. There was also a large gap between that wall, and the plywood base for the sub, since the wall is at an angle, and we didn't cut the plywood at an angle for that. We should have though.

I'll try to remember some pics for that :crazy:

 

I'm gonna take a lot of pics when I install my 10" Kicker Comp VR in that compartment. :p: :D

 

I did the same thing, but couldn't keep the bin door because I went to a 12". I have an 85 so both compartments are usable (think after that ABS took up most of the space on one bin). Still need to finish my MDF mount, but normally just have the carpeting laying over it, so it is pretty much hidden from view.

 

I don't suppose you have any pix of the install?

Did you fabricate a box inside the storage area, or did you seal it the way it was described above?
