ok so i finally need that boom boom sound in the car. I tried this method so i will have room in the back and have access to the spare tire.

 

here is another angle, i'm gonna try black cloth to make this look stock

 

the box turned out to be 1.32 Cubic feet, i'll place some cotton inside to make it a 1 cubic feet to match with the sub. The one i'm using is Alpine Type R 500 watts rms/ peak at 1500 watt. I wish i could find a blue sub but i guess i'll settle with power rather than look.
By the way if you dont know how to measure cubic feet of these type of box, here is the lesson. I filled the inside with water till it's full and then just pour it into a cubical box to measure the cubic feet volume =] Use your algebra math skill

 

here's some update pics

 

nice. that looks like either fleece or suede covering. lookin good tho.

 

thanks, i tried to find that cloth that are on the door panel but had no luck, if anyone know where to find these material, let me know, much appriciate.
by the way, nice blue car dude =]

 

here is the finishing look, i was be able to use the trunk space and have access to the spare tire

 

Nice, looks good.

How does it sound??

Do you shake all the windows and mirrors?

Good job.

 

oh dear, i just finished the installation, this is so far the best box i have built lol. It's have a very nice warm strong bass, i tried to crank it up to 8db and my rear view miror shook all the way down. If anyone was gonna install a system for their car, this is exactly wht i would recommend. It's type R alpine and Hifonics brutux BX1500. Try to calculate your cubic feet to 1-1.3 3/4" wood. I don't know if it was the cubic space inside the car or what but it sound very good, better than my Chevy Blazer. I will take some finished pics later tonite when i get ahold of my camera
