i suppose a 2-ohm resistor on each one would fix that. By the way I got these speakers for basically nothing and they're better than stock. I traced the problem to broken corroded wiring. That happens when wire is made on a Friday before a long weekend at the wire factory.. corrodes itself inside the insulator. I know if I wanted a boomin sound system, I would get the whole setup amps and all however in my opinion...here goes... subwoofers are a bit too "donk" for me.
