SO today im working on getting the wiring in place for the sub im installing in my 07 limited.

My question is this, are the outputs from the radio filtered, as in, do the front speakers receive full spectrum sound are the rear speakers (subs) just low pass?

Im going to tap the factory wiring pre-amplifier and piggy back those rear speaker inputs to the amp for the sub, im just wondering if I should pick up a low-pass filter or not if the signal is already filtered by the stock headunit.

 

So far as I know, all 4 places receive the same signal.

 

The rears are filtered in the amp so if you break it out from the HU you should be getting full.

 

thanks, for now i want to leave to stock amp in place until i (might) do a full system.

 

how can i wire the rca jacks straight into the amp??? back subs dont work ..connector broke...what color are the rear subs on the amp clip?
