Thanks a lot forthe support. asume that in a matter of weeks i wil start the work on this small project. I like your design because is more simple to make in comparison with the other more complex designs.
The only problem is that for the moment i find it very hard to get a subwoofer like yours(here it cannot be found) and i think i will go with the something similar from pioneer or alpine(do you have any recomandation?).
