Were you able to upgrade the speakers?Hey there, I just bought a '21 XSE with the standard audio as well and plan to upgrade. Since I already have some Audiofrog GS25 and GS60 speakers laying around from a previous upgrade, I'm planning on going that route up front. The GS25 should just drop right into the dash and give a nice mid/full range upgrade. I took the door panel off on mine and the original speaker is a 6x9 looking housing with a round 6 3/4"ish speaker in the plastic. So one of those metra 6.5 > toyota 6x9 adapters should work. I'll document it all as I go, but I have to figure out a good small amp/DSP combo for it too.
