Pathfinder Subwoofer
can I install a subwoofer and amp to my factory In Dash unit?
I have a 2000 infiniti qx4 (pathfinder). I found a Great Deal on subs and amps with all wires. I just would like to know if I can use my factory in dash unit or do I have to buy a new one
DO NOT JUST TAP INTO THE WIRES!! You will fry your in dash and factory amps. You need a hi-low converter. This you should tap into the wire that goes from your factory amp to the speaker. The QX4 is a lot more complicated than a normal Car Stereo because it uses amplifiers at each speaker. Use the HI-LOW converter.
My suggestion would be to get a new in dash anyway. Even though you can do it without the the new in dash, it will sound much better with an aftermarket unit and you will have greater control
