Need info before installing new system

[Anonymous]

I have a 2003 US spec SMT and want to replace the stock system but before I start I was wondering about hardware for the installation. I am putting in a Kennwood HU (KDC-3027A), Focal Componets( 165 V Slim) and a Blaupunk amp (GTA 250). I spent some time reading the other threads but I can't figure out what else I should get to get a nice clean install and prevent me from running back and forth buying unexpected parts as I do the installation. Any one have any suggested parts such as the wiring harness, mounting brackets, ect? this newbie thanks you

The only parts you will need are speaker brackets (make your own or use the plastic Mr T 1's)

A Toyota loom for the kenwood headunit

wires 12 aug about 4 -6 meters and a soldering iron or crimpers

If your instakling the amp make sure you buy an amp kit with fuse hodler and earthing straps etc
