ok..i plan on replacing all 6 of my speakers...but i was wondering, what size are the tweeters, i think im gonna change from pioneer speakers which i love..and try some audiobahms which ive herd are very very nice. anywho..so im also gonna be wiring the speakers to an amp..i have an MTX amp that rated extremely high 90x4 and im never gonna give it up!! its gonna go into all my cars..lol. so im wondering, if i hook up the front channel to the speakers, AND tweeters...assuming they are all 4 ohms, wont they be wired to be 2 ohms?? i know about wiring...but w/ subs, but why would the speakers be different?? so anyone can give me some answers!
