My uncle used to have one of those (25 years ago)... i always wondered what's the plastic grill on the back for?

Put a hayabusa engine in it, this should give you room for a bigger battery

The plastic grille is nothing. The designer wanted the tail lights to go all the way from the bottom tot he top of the hatch and designed the parts that way. Renault did not find it cost effective so they slapped a plastic grill to cover the holes.

I posted a pic of the car in the "the donut shop" titled. "the beast"

The project with this car is a no go. I'm not shopping up a classic car. I'm gonna continue with the MX-3 I have but it needs a new motor before I get going.

if you build the wall properly sticking to the very outside of the interior ull have way way more than 10 cubes to work with.

id recone 2 of ur subs to 15s and use them. Build the enclosure as big as you can for starters and brace it to the outside of the car as much as possible. Minimum two layers of 3/4 mdf in all spots plus as much 2x4 bracing as you can fit.

Build ur back wall as strong as possible.

Build the baffle 4-6" thick and heavily rounded over.

Have the wall farthest to the passenger side molded into the b-pillar.

Deaden the cab with the best deadener you can afford

Shrink the enclosure bit by bit to tune

it can be done without "chopping the interior" a 6" baffle is too thick though, and stay away from bracing the box interior with 2x4!!! if you can manage though, get a plate of 3/16" steel and solidly laminate it to 1.5" of mdf. screw a frame of 2x4 around the perimiter you you can move the rear wall inward and secure it while tuning.

you will probally tune very high so keep that in mind while tuning. try port length after tuning without it, it will strongly indicate wether your inclosure is too large and once you are at the correct volume, your score should decrease by tuning down using port length, it will only be a gain when your enclosure is too large.

and careful with your angles inside the enclosure....a slight angle will help push the rear wave toward the vent \_____/......like this! big 45's will cause your wave to reflect dramaticly and collide with the waves that reflect off the flat surface of the rear wall.

if you try big 45's while the enclosure is too large, it will apear as a gain only because they are taking up volume.

yes there are guys on this forum with more "wall" experience, but no-wall follows similar principals regarding enclosure, just a little more work to get the dbzzzzz!

try it for sure, dont be a panzy lol GOOD LUCK!!
