So, n buddies of me now wants to improve his bass in the car a bit. he has a vectra stepback, with ski bag and also openings in the hut rack. the music is mainly electronic, trance, hardtrance, techno… that’s why I thought that a band pass here would be an optimal solution. since he would have installed the whole optically somewhat attractively we thought to build the front side of the housing out of plexiglas. now the questions: 1: which sub and which level would be recommended It would be worth it ( both for max 500€ ) to found optically he would prefer the installation of 2 woofern, which would be recommended there?I think that a higher quality would be the better alternative. 3: how thick does the plexglass have to be, 20mm ? 4: how do I get the plexiglass on the edges really tight? so, that’s it for now in the rough… thx & gruss alex
