Yep I've been playing around with tuning it and so far it's been great. The plan was to install the tweeters on the door, but getting the wiring across was going to be a pain, so currently they're just fleece taped to the dash
I also bought an underseat sub (

I currently have all the audio components on a marine ply board, and have that behind the back seat. I'm planning to add a fridge/inverter/drawer system so once that's all planned out I'll mount it all in a more permanent position and trim the cables so there's less spaghetti everywhere:

I've got 1 8 Pin DT connector for audio in from the factory head unit (this preserves the factory fader/balance control) and one 12 Pin DT connector out for the 4 speakers and 2 tweeters. The sub I wired directly to under the front seat.
My amp also has 6 inputs, so I'm going to wire the UHF radios external speaker to this so I can get that through the speakers too.
