I bought the $249 dollar CD/MP3/WMA headunit from The Warehouse and I am IMPRESSED++++ with it. It puts out 50w x4 and doesn't skip or anything, it even survided the crash when I rolled the car three times and I pulled it out of the wreck and put it in the new celica
With the Celica stock speakers which are allready fantastic, the 50w x4 makes them thump, so far everyone who has gotten in the car says, "Oh.. you got your sub hooked up, sweet!"... I can't wait wait to actually hook up the sub now, hahahaha.
