so i just bought the INFINITY KAPPA 6"x9" 3 WAY 330 WATTS 693.7i and it came with crossovers can i just hookup the crossovers to the negative and positive wire from my car? because i did it and it works fine. so the speakers work and the tweeters. because i dont feel like buying a amp for the speakers. thanks.
just hook the crossovers where it says source or input to the wires from the car and then the woofter to where it says and same with tweet. and it will work fine. just get an amp is you want them louder
