Your MT is deterrent enough for the 99.9% of average car thieves.
Don't listen to the. 223 with suppressor guy, what you need is something like a 300BLK with suppressor. Something subsonic to really be quiet and not draw any extra attention.
I've seen issues like this if you don't disconnect the battery beforehand. Something about not disconnecting the battery but unplugging the sensors makes it go haywire.
It's a pain in the ass how they have the fogs now. You have to take the entire front end off to get the facia off that they're mounted behind. Made the mistake off not aiming mine (after market) correctly and now I have to take the front off for like the 4th time to fix them lol
Curious if they replaced the evap box, which requires removing the entire dash. But if you bought new and hadn't had that issue not sure what it would be.
Sounds terrible though!
Not showing that this posted earlier, but there are options to upgrading the amp if you want to spend the money. I'm sure there are other cheaper options as well.
However, this is an excellent reference video of how to remove interior components.
