Ok I got a question about crossovers. I have the Avic-n1 and I have a JBL BP600.1 sub amp. The Pioneer has a low pass x-over on the sub out that is adjustable between 50-80-120 hz and the jbl has a low pass x-over built in as well. Neither one can be turned off. The pioneer sub out can be turned off but the x-over can't. The jbl is always on as well since it is a monoblock they didn't let you choose fullrange just low pass. So what will happen with the 2 x-overs on? Should I try to have them exactly the same or what? It just doesn't sound right the way it is right now. Sounds like the frequencies are way off due to having 2 x-overs maybe fighting each other. Someone please clarify this for me.

 

it won't matter if both x-overs are on. what ever the lowest frequency is will be the frequency going to the subs.so if the pioneer is 80 and the jbl is 50, the 50 hertz will be the x-over point.
a little note, the jbl has 2 sets of inputs for rca's. if you are using only one set, get some Y adapters and connect the 2 sets of rca inputs together. you will see an increase in sound.

 

Thanks for the quick reply. I already have the splitters on there. I've had this amp in other cars before and I love it. I haven't had any issues with it ever heating up or shutting down and won't buy another amp until this one dies. It has more than enough power for me and Is by far one of the best amps I have owned. I have the same amp in my Protege 5.
