WooHoo! I just finished my DIY 15" Sub project. (i had a lot of help from the DIY forum -thanks!).
The sound is incredible and i am very pleased. The bass is deep and tight.
The total project cost was less than $300 (with the old/unsed amp i already had and labor from Dad in his workshop).
Now movies and music have much more definition and impact.
See the DIY forum for project details.
