This is the thing. I'm confused about the 4 speakers/2 tweeters. A 10" sub can be powered with a bridged 2 channel amp or a mono amp. The 4-channel amps power 4 speakers. Do the tweeters have to be powered as well, or are they joined with the front speakers. I've been been reading up on car audio systems but the tweeters still confuse me. If you guys can, just explain this to me. Thanks.

 

Components come with a crossover that splits the signal. High's go to the tweeter, low's to the woofer. So a 4-channel amp will power the front channel speakers (woofer/tweeter) and the rear channel speakers (coaxials).
