[QUOTE="Doxquzme, post: 8864916, member: 689267"] I do have over forty years audio experience, but I don't know everything for every car ever made, that is true. Crutchfield has a huge database and does many installation on 1000's of cars, they too know quite a bit. As for the speakers referenced in the chat, doesn;t matter, I was trying to get information relative to if all the wire leads were dedicated or not. I didn't need to ask about the rear speakers because as general rule, you do the frequency dividing one way or the other in a factory/OEM setup. My suggestions are based on a lot of experience, not just conjecture. The question then becomes, are the wires dedicated frequency/speaker dependant, electronically crossed or passively using an inline dividing network (crossover). If it's electronic as the video suggest it might be, then run the bass wire to the bass driver and the tweeter wire to the tweeter. The fact that a tweeter is connected to the woofer chassis, coaxially mounted to the pole piece, mounted somewhere else, mounted across the grill, etc. is not the relevant issue. If as the commentator in the vid is correct and the amp is doing the frequency dividing work, then yes, wire the bass wires to the bass drivers and the tweeter wires to the tweeters. In the drawing I provided, you would just snip the wire coming out of that magnet and connect directly to the tweeter wire feed from the amp bypassing the cap (which you could just tape off or remove altogether) and the other wire to the woofer. If a coaxial speaker has no cap inline it will have a separate dedicated connection on the bass driver frame. Wire it up respective of which goes to which - done. ;) [/QUOTE]
