I recently ordered subs and amps and such and I was wondering, if I placed the sub facing upward in my trunk would this be a bad idea? its in a sealed box too.
That might cause excessive trunk rattle . Its a trial & error thing - generally facing it to the trunk is the prefered choice. try both ways & pick what u like best .
I don't know what that car even looks like but U cannot really damage your subs by where u put em - so like i said , go actually try different placement positions & pick 1 .
