I have fitted a pioneer "DEH-50UB" head unit and four "Juice JS63" 6.5" three-way speakers in the doors. Although these are three-way and include tweeters they are low down so loose some of the highs. I am wanting to wire in a set of tweeters in the A-Pillars or mirros covers taking a feed directly from the cables going to the front speakers. If I hook up using splice connectors to these cables and buy tweeters that have built in or inline crossovers will this work? The main issue I am having is that the tweeters I would like to use are the JBL GTO17T but these are 2ohm. Is this Ok as I don't understand about the resistance.
