VZ ute audio install help

[blueheeler-aus]

So far I've made a custom fiberglass sub box, & installed a reverse camera and runing all the wiring for both ready to be hooked up to an amp and a new head unit. I'm now looking at the install of door speakers/crossovers and tweeters, + the amp and head unit. I purchased a set of focal 165KR2's. After taking the trim off the drivers door it looks as though theres no room to put the crossover inside the cavity of the door. Ive seen 1 video on the web where they left it in the door pocket on the outside but that looked crap. There must be a good spot to fit both crossovers on the driver and passenger side. Any suggestions and pics would be a great help.
Also can someone tell me the best spot to feed wires from the battery + through the firewall to connect to the amp.
I was looking at attempting to replace the factory dash tweeters but I cant find any diagrams on how to attempt this without breaking something, I've only found a the how to take apart the centre console.
Any help on any of theses problems would be appreciated.

I Jammed the passenger one up in the gap to the left of the glove box - I wrapped it up in foam pretty well before so it wouldn't rattle though. I did the same with the other side.

Yeah I had a look at it today, perfect spot for both crossovers, put them in today. Thanks for that one & only. Now just need some advise on the wiring to the battery & information on the dash for the tweeters.

I have my tweeters where the stock ones sat, but I fiberglassed over the vent looking bit and put a 35mm hole in the middle so they sat flush. As for your power i ran mine over to the passenger side of the engine bay and through a grommet under the alarm horn (right up behind the strut tower), behind the kick panel, along the side under the plastic covering the kick board, then to the amp. For the earth I bolted onto the seat mount.
