New to the forum, second post. I have been reading about upgrading the speakers and sound on the LC/LX. It seems that almost all of the post for the upgrades use an upgraded amp? and some sized speakers are different 6.5 vs 6.75. I am not an audiophile and really just want to upgrade all of the speakers as the stock speakers seem pretty lame and possibly one or two might be blown. Is there a problem with just upgrading the speakers and not the amplifier. 2005. The subwoofer looks to be a 6"? and the doors 6.75? Only want to spend a couple hundred bucks total. Thanks
