How do you wire kappa 6x9 693.7i (dual coil) with kicker 600.4 amp. There are two voice coils and a block that has 4 wires out to the speakers then the positive and negative to the amp. I am asking because mine is not sounding right. I have the positive/negative to the amp and then the 4 wires +-+- to each coil on the speaker. 1 sounds great and one sounds distorted. Do the ohms matter when wiring them and should they be bridged? Thanks Brad
