My 240 wagon has never had a radio installed in it. I'm looking to get a CD head unit in the near future, but I'm at a loss for the installation. I know how to install car stereos (I've done it before), but I'm a little confused about the setup here. I know that there's wiring for two front speakers, but what about the back? I've seen 4" speakers mounted just behind the rear doors in other 240 wagons. Is that the standard mounting place? Is there any built-in amps or anything that I should know about before hooking anything up? Also, I'm looking to add some bigger speakers in the back to give it some bass (not something that's going to shake the streets, just enough to make music sound more natural),what would you guys recommend for positioning? The only thing that I can think of is to build a box or two to house speakers, as I can't really see any place to put any. Thanks in advance! <IMG SRC="http://www.swedespeed.com/ubb/smile.gif"><P>
