i just got the 6 1/2" d661a componets for christmas. when i was wiring them up i got one side in and, tested it. the tweeter sounds strange. like very unclear. there was a point were my mark got messed up and i lost which one was positive and negative for the speakers and i thought i had the correct one. if im out of phase could that make the tweeter sound weird.? everything else is fine, thanks for any and all help.
