Looking for someone that has put a box in the hole for the roadster. Got an 07 and a 10" sub I want to install. I hate free air so I'm looking for ideas.

 

ppl have fiberglassed/dynamatted the cubby...but thats as close as you will probablly get to a BOX

 

but here, get this -> http://www.wickedcas.com/product.php...2&cat=0&page=1

It should do the trick...

Good Luck - and let me know how it sounds!

 

The problem with just trying to make an enclosure of the space in the cubby behind the seats is that it is way to big for a normal 10" sub, easy 1+ qft. With that big volume the sub will not take much power without issues of failure.

I made two enclosures of MDF/fiberglass in my ZR, but I also made a new panel to go across. I"m not a fan of 100% fiberglass enclosures unless they are really thick and well dampened using dynamat or similar. It will generate a hollow sound if it is just bare fiber glass.

I'm looking into making a drop in enclosure to replace the factory sub but still nothing ready, hopefully later this spring when I have some more time.
It will be 0.6-0.8 qft sealed for a 10" sub firing into the seat and held in place using factory bolts.

 

What about putting a box in the trunk would that cause too much trunk or tonneau rattle? I want to put a sub in the stock spot too.

 

OP this is your best option.
