Just wanted to say thanks to @Gregs24 for the post and answering my messages, ARAMP1 for the link on the connectors and Ninjacoupe for the link for the grilles. Made the whole experience very good. I went a slightly different direction with my 2023 Mach 1. I purchased a used woofer w/enclosure...
Normally a size 12 wide, I am having an issue with catching the brake when pushing in the clutch. Gonna try these. Picked up used and cheap. They are a bit narrower.
2023 Mach 1 Mustang wheels including sensors with Michelin Sport Cup 4 tires. 275/40R19 (10 inch wheel) rears 255/40R19 (9.5 inch wheel) fronts. Like new. 900 miles on them, never smoked. Wheels are 99%. One of the rears has a nick in a spoke, shown in the pics. $1700. Serious offers...
