My brother has a very similar corolla. 2015 I think. The Alpines may be a different ohm load for the factory power and it may be shutting it off. Are the tweeters factory and what model Alpine speakers?
The factory corolla tweeters have a crossover capacitor ..so that should keep your ohms stable ...if I was to guess the terminals are occasionally touching metal of the door and shorting the radios amp chip ..you can check on this by looking close to where the wires attach ..solution..wrap tape around terminals on speakers to make insulation ...or and add duct tape over metal a couple layers where speakers might touch..
I have an aftermarket head unit, it's a Kenwood, not sure the model but was around $600 dollars and no the tweeters are not factory I put some cheap sound stream tweeters on there as far as model for the alpine speakers I can not remember, I bought them at bestbuy for around 100 bucks if that helps
I replaced the factory tweeters with some sound stream tweeters, I noticed the positive and negative both have 2 wires running to them so my guess is one comes from headunit and other leaves to door speaker, and I put in a speaker baffle because I thought maybe the wired were getting wet but the problem continues so I don't think it is touching metal, and I did use screws to mount but I'm not sure if it's warped I will have to check on that one
A speaker wire grounding to body will shut a Kenwood deck down so will a tweaked basket with voice coil short ..both issues can be intermittent
My head unit works fine the subwoofer and rear speakers still play music, it's just the 2 door speakers that stop after a day or 2
Are the rear speakers stock ...some corolla owners are having a problem in the picture where the rear
The rear speakers are also Alpine, I haven't had issues with those, I previously had kickers on the doors but switched them thinking they were the issue
