ok, so i'm pretty unknowledgeable about stereo stuff - and i don't know where to begin searching. i'll list off basically what i want to do and some questions and any assistance and recommendations on gear you might provide would be great. so essentially what i want to do is run 4 regular speakers and one sub. i want to build a sub box similar to what greg72 has done on the drivers side. i might do a second box, but for storage on the passenger side. i'm thinking to put my amp under the drivers seat, and maybe use some of that grating which you can buy at home depot to protect it from stuff rolling around. i have a couple ammo boxes for a center console, and i was thinking to put my deck in there. i think i'll drill some holes around the faces of the boxes where the stereo is actually attatched for air flow. i'm not looking for impecable sound, but i want it to sound pretty decent. i want the sub to just fill out the sound of my music - i'm not looking to ricerize my truck. my front speakers i'm just going to put in the kick panels up front. i can't decide what to do with the rear speakers - the only thing i can think of is to build them into the storage and sub boxes and make the point upward - but i don't know if that will kill the sound. i don't really want to put them in the cargo space, as all the stuff i keep back there might inhibit sound. i was also thinking to build tool boxes into the walls back there anyway. so here's my main questions. i'd like some recommendations on how to mount my rear speakers (is pointing them straight up on either side of the truck ok) and i need some recommendations on cheap gear. again, i'm not looking for anything amazing, just relatively low-end, but decent stuff so i can have some tunes. thanks for any help!
