I installed it myself. a 1000 watt Audiobahn amp with an 800 watt 10" Audiobahn sub.
It took about 7 hours to install because i had to find a good place for the REM wire. My HU doesn't have anywhere for it, so I had to attach it to an open accessory fuse.
holy fuck is it worth it though. it felt good to do it myself too. I ran all the wires through the door panels and back paneling, put the sub box in the open area behind the seats and mounted the amp on top of it.
so far i've done all the modifications on my truck myself which makes me feel good about it.
And the sub is loud enough to make a nice impact, but it's not violent enough so i all hear is rattling. it's fucking perfect.
