I have a 2004 seadoo sportster LE and want to install a stereo in it since it didnt come with one factory. wondering if i could get some help on where to install the headunit and speakers. i know where i want to mount the sub but not if its the best location. i was also told i will need to build a special box to keep moisture/water away from it. if this is true could anyone be able to give me some ideas on the best way or point me in the right direction? also im sorry if this thread is in the wrong location.
