Glad to be part of this forum.
I'm trying to add a sub to my C4 and have researched a ton of old posts. Most are too old to see pics of the Passenger side storage compartment Stealth sub.
Any thoughts on how to do one or but one ready to install?
I hop I didn't miss any recent posts about it. Looking to do a 10" sub.
At the same time I'm looking for the best option to install 6.5" speakers in the door but don't have an enclosure there other than the Bose one.


Thanks

 

I almost went with that option of installing one in the storage compartment but instead made to mounting adapters from 1/2" plywood and used 8" shallow mount subs in the stock speaker locations. I get plenty of bass and used a 6.5" component speaker system in the front stock speaker locations. I used the back half of the enclosure and 1/2" plywood for those. All is hidden and there's no evidence of aftermarket speakers. It should be just a matter of making a template for storage component and fabricate one. Could make it out of a piece of cardboard and fiberglass for that matter.

 

So am I looking at this correct?
The first pick with no driver is the one for the sub?
The second pic is the front door with the components mounted? You sliced the BOSE enclosure so you could put a new top on it and remounted inside the door?
So you wouldn't have any speakers in the back other then the subs?
All your mids and highs would have to come from the components only in the doors?


Thanks!

 

That's exactly what I want to do. Good to know a 8" will fit. This is in a coupe and not a convertible right? The rear bose speaker locations? Do you have pics of it installed in the car? I found mb quart 8" shallow mount woofers for like 60$ a pop.

 

I made up a similar template out of Lexan.. My concern was. I have a Alpine Type R 8" sub in it's own enclosure - driven by a Pyle PLBA530FRD this combo can take on many 12 - 15" setup's. I'm sure would crack the fiberglass. Factory compartment.

 

Sounds incredibly awesome! Could you give any suggestions to me. Do you have any pics of your sweet set-up?

 

I used most of the compartment behind the passenger seat for my box as well:




Its like GM wanted Vette owners to have subwoofers!

I just installed a sub-woofer in the storage compartment behind the passenger seat. I have a convertible so any loss of available space is a big deal.

The Kenwood KSC-SW11 is a really cool sub-woofer and its easy to install to an existing system with no sub-woofer output, or a new system with a dedicated controls. Its really small and tucks down into the storage space; up tight to the waterfall.

I installed a layer of high-density 1/4" foam on the bottom of the storage area and then used OEM black carpet to line the walls. It just made a nicer install. Amazingly, the sub really kicks. It doesn't take much in a Corvette as the cabin is pretty small anyway. I mean, the sub won't rattle people on the sidewalk nor win any decibel competitions, but it's incredible inside the car where sound quality is paramount. I presume you are more interested in how it sounds in the car than in the car next to you at a stop light. It is self powered so no need for an additional amp.

Trust me, its a great little unit and such a bargain. I'll insert a photo of what it looks like below. I don't have any of it installed in my car yet. Check it out though.

 

That's very cool. Is the storage compartment the same in the Vert as it is the Coupe? Mine has a plastic insert inside each of them which I assume I would dispose of and create something different to hold the sub in. Thanks again

 

I don't know if they are exactly the same or not. I would think so, however.

Mine has the little plastic trays too. I installed my sub below all that on the passenger side. I removed the plastic trays and the carpeted liner and installed the sub on the bottom -- tight to the panel that separates the cubby from the passenger seat. I've been told that panel is called a "waterfall". That made it so the liner and plastic tray would fit back in as they always did. The only thing is that I'm sure the plastic tray is going to rattle from the subwoofer. So I put felt weatherstrip around the lip of the tray to prevent it.

 

This is installed as my pilot test. Sorry not very Pretty.. The Alpine SBR-S8-4 Sub. I purchased with it's own enclosure. I found the combo $50 more then the woofer alone. Free shipping.. Excellent deal. The Pyle 5 channel amp has plenty of power. To Drive 4 speakers and your sub. Tuning to match your head units output. Later. I will attempt to complete my Lexan face Alpine woofer and separate ported enclosure in the factory compartment tray. As we know. a 8" sub can be installed in this space. I'm positive installing this Type R directly in the tray compartment will crack the car. You would not believe this is ONLY a 8" sub

 

Hey... By the way, I wanted to mention to anyone who cares that working with ABS is easy and cheap. I read a thread on a tuner site about speaker enclosures and building custom center consoles, etc. One of the respondents was talking about using ABS to build things. So, interested, I decided to get some and try it myself; especially since there is so much ABS used in Corvette interiors and exteriors.

I found a local plastics vendor called Keltech Plastic in Tacoma. I bought a big sheet of 1/8" ABS for about $10. Its easy to cut and sand with a Dremel tool or any other wood working tools. I also discovered that you can bend it without snapping it in a sheetmetal break. I had to build some things with it to augment the rear speaker installation in my C4. I bent it and cut it, riveted it together where necessary, then softened it with MEK and glued with ABS cement. It works really fast and really well. I also found on another website that if you take ABS shavings and mix with MEK you can make a creamy ABS paste which you can use to glue and fill; even build whole sections and mounts. I took a Kerr fruit jar and used fine shavings from cutting the ABS to make the ABS concoction. I also added part of a jar of ABS glue. It works well to brush it onto areas where you want to fill or build up, then I'd trowel it into the place and shape as needed, and then put wide masking tape over it to hold it in place and make a smooth finish. After about five hours of sitting, I could peel the masking tape off and sand.

It works so well that I'm irritated I didn't find this out years ago. There are so many occasions when it would have simplified customization or repair of something.

I just thought I'd share it with you guys in case you wanted to build enclosures or something that isn't heavy like MDF or fiberglass and looks OEM.

 

The above, having a non-Vette project in mind for dash updates.
