SO YOU CAN wire 4- 8 ohm tweeters per crossover and they remain 8 ohms each. This site says,"4 speakers wired in series-parallel, two of the speakers are wired in series with each other, other two speakers are wired in series too, resulting systems are wired in parallel,if all four speakers are 8 ohms,result from this wiring is 8 ohms." The diagram shows(i think i imagined it this way before seeing diagram), + of crossover wired to + of 1st tweeter, + of 1st tweeter to + of 2nd tweeter, - of 2nd tweeter to + of 3rd tw, - of 3rd to - of 4th, - of 4th to - of crossover. So maby i will wire 4 tweeters per crossover this way and they will remain at 8 ohms each and have a longer life than only 1 per crossover, even though im using a crossover with improper 6 or 12 db. Im using what i have til blow out day.
