Question about Car Audio & Video
One has a hole and they sound blown. how do I fix it
Do a google on "speaker reconing" - you will find some services that can do this as well as companies that sell kits for you to do this.
I have not done this myself, but would recommend a service - unless you are quite gifted with your hands using tools.

On the amplifier side, I will need the wattage, and frequency of the speaker to tell you what amp you will need.
Subwoofers differ in only one way. You get an "Open Air" and a "Closed air" subwoofer, That being said, you'll have to check on your magnet which one you have to make the boxes for that sub. If it is an "Open air" Subwoofer, you should see a "wire mesh" or "grid" in the centre, at the back of the magnet. If it is a "Closed air", the magnet will be solid with no hole whatsoever.
If it is a "Open air" sub, your boxes should be sealed with silicone, and no ports are to be cut in your box.
With "Closed air" subs, you should have 2 ports below your sub and the port sizes should be around 50mm in diameter. You should start with a 100mm long piece in the one box and add 50mm increments to "tune" the port up to 250mm, depending on the frequency of bass you require.
On a 15 inch subwoofer ranging between 80Hz and 120Hz, the box size required should be around 27 liters, meaning that you will end up with a box of 16 inches high, x 16 inches wide, x 16 inches deep. Or 320mm high, x 320mm wide, x 320mm deep.
