Well it not much but I can install radios,subs,amps,door speakers, and maybe anything else that has to do with radios if needed done. I've done all my own installs. here is a few pictures of my install of my sound system in my tundra. I have a pioneer radio, door speakers 6 1/2 in all doors. Sub 12inch 1200 watt and power acoustic 300 watt amp.
