Just bought a 2020 Expedition Max with the 202A option package that had a few other options (i.e. Nav., Captain’s chairs, sunroof). Opted for this over the Limited due to about a roughly $6,500 price difference when similarly equipped. My kids are just going to wipe buggers on the inside anyway. However, I just couldn’t take the 6 speaker stereo. I’m not looking for amazing sound, but this stereo is weak. I’m totally fine with the stock Bose setup in my Q7 and Boxster, but this just wasn’t going to work.
So at 350 miles all the door panels came off, and new speakers went in. Also put in a Rockford Fosgate PBR300X4 amp which fit nicely in the extra space towards the dash under the center console (a bit up from the cupholders). Hopefully it won’t overheat (time will tell). I retained the factory head and spliced in to the factory harness (using line level inputs). Made me queasy in the process, but all went fine.
Project is almost done, and it sounds much better. Not perfect, but not like crap like before. I can hear the stereo now over the road noise.
However, just wanted to post a few ideas that might help:
Easiest point I found to run power for the amp was the grommet for the hood release cable on the driver side. Unfortunately, that’s opposite the battery so it’s not ideal, but it’s easy to reach.
Tweeter wire feed for front A posts actually split off in the door at the factory speaker, not the head unit. Made using the aftermarket speaker crossovers (mounted in the door) very easy. I retained all factory wiring.
Cutting holes in the rear door panel for new tweeters with a dremel is very easy. There are already holes (probably for the B&O system) in the back of the panel that almost act as a guide.
System still lacks deep bass, but for a $700ish upgrade, I wasn’t expecting a ton of bass. The sound is a bit “crisp” but I don’t hate the sound anymore.
Last step is the Forscan removal of the fake engine noise (and auto start), which I’ll work on soon.
