about the sound system:
If you spend the money in the right places you will only need half of the speakers you mentioned. I upgraded all the (4) factory speakers to Kiker ones and a pioneer pro sub. For the bass with kenwood radio and kennwood amp for mids and highs also a kiker mono amp for the bass and I have more volume/bass/mids & highs than I know what to do with.
If you were building something other than a work truck then 9 speakers might be ok but for a work truck....overkill.....Unlesss you park the truck down the street from the job site with the radio blaring so you can hear it from far away, lol.
