OK, I have a JBL 6-1/2" 2-way component system in the front doors only and JBL 6"X9" 2-Way speaker in the back. All hook up to a JBL 4 channel amp. Now when I open one door (L or R) I get more bass in the car, What's up wit dat? did I hook something up wrong?
Hollaback. Thanx.

 

Cancellation maybe?


Did you try flipping the polarity on one driver?

 

No I didn't, but I will try it out. Thanx.
