I actually like the stock head unit in my Scion. It has more features than any of the aftermarket units I have hanging around, and it plays MP3s.
But, the speakers lose it at any kind of volume. They're OK, but they break up at the levels I like.
Someone posted something in a Scion 'Forum' about making speaker baffles for larger speakers. It can't be all that bad, can it?
Oh, yes it can!
THe speakers are one piece with the 'adapter'! So, you can't just pull the baffle, remove the speaker and install a new speaker! I was going to order something from either Crutchfield or EBay, but someone posted instructions for making adapters, so I'll get some 3/4" MDX and make them. But, I don't have a jigsaw!
So, I got the back panels out and made my discovery. I have three sets of MB Quart 5.25", and one set of 6.5". I figured I'd remove the 5's from the rears and install the MB Quarts.
Time was running out; it was approaching 5:00 and we don't have any decent "Big Box" stores arond here, so while looking for a fan in the cellar, I found some 6" 'adapters' I had yanked from a Honda to use in my Supra for the front doors. I had them modified for my Quarts, so, I stuffed them in the Scion, but only one bolt would hold, so I modified the basket and mounted them.
It was tight getting my large frame in there, but I got them in, and it sounded GOOD! I figured I'd try the fronts.
Same speaker set up: the adapter IS the speaker. And besides, WHO THE HECK RIVETS SPEAKERS INTO THE DOORS?!?!? Damn!!!
Project for another day...
