Im looking to replace my speakers at the front with 17cm Component speakers. They come with tweeters and crossovers can someone please tell me if I would have to use the new tweeters and crossovers or can I just wire in the speakers and the tweeters that already exist would this sound ok or would I get phasing issues and/or it would just sound crap. Has anyone done this?
Also If I have a head unit that provides 50W x 4 output and front and back speakers have a RMS value of say like 70W each what does this do to the sound do they just not work to their full potential or something.
Any help much appreciated real newbie to this kind of stuff!!!!
