Alright guys i just got 2 Alpine type R SWR-1040 10" for a hatchback mustang how should i do the box. ported or sealed? power is not going to be a problem they are going to be over powered big time :cool: I originally wanted to get some 12s but i ended up getting some 10s cheap so i have a huge amp for em now. but anyways anyone know some good dimensions and perhaps a page that has a tutorial on building boxes. thanks [img]graemlins/beer.gif[/img]
