I am going through the process of adding 2 subs to my JL which has the the 8 inch alpine upgraded system. Bought the drivers side stealthbox and an additional JL 10TW1-2 which is the same sub that's in the stealthbox i ordered. Figured some of you may want to see how I built out the factory sub housing to hold this sub. Photos below.
Since the sub was smaller then the cutout hole for the factory Alpine sub, my plan was to fabricate at least 1 MDF "ring" (found 2 to be the right amount) to mount into the existing 8 screw holes, using the existing 8 screws.
I started by building the first ring which would sit into the recessed slot in the factory housing. I used a 1/4'' MDF sheet to cut this first layer.
I used the trim ring as outline and then sanded away to get it to fit snug.
I then built a second "ring" to sit on top of this one and fill out the rest of the opening. they are not the same shape as the second layer i wanted to go all the way to the upper edge of the factory box.
Then drilled holes and counter sunk the top so that the screws will hold it all together. Missing some photos in the timeline here, but i think you all will understand. Then measured 230 cm hole (matched JL audio hole spec size) cut it out with my jigsaw and sanded some more. I test fit everything many times to make sure i was happy with how they were aligning.
once i was happy with the fit, spray pained it black and thats where i am at so far. I am still awaiting other parts to arrive from crutchfield and JL including my amp, wiring kit, and the stealthbox for the driverside.
Will add more once it's all in.
