okay so i have a cobalt wanted to go with an alpine type x or i wanted to get an olympus but a few reviews have driven me away from the type X
i have a kicker 1000.1 so i think im going to use two kicker alpine type R's
so now im going to build a ported box but i have a cobalt with VERY limited space
so i was thinking about aeroports does anyone have a design with round ports for type R's?
what do i even make them out of!?
