It would be best to kill those lows on the doors, you could go up higher esp if you are doing 6 Db/octave, like 500 Hz or so, it will sound cleaner and save those from getting slammed real hard. If you have an (at least 4 channel) amp for the highs why not just do it F/R?? EQ them together if you have to.I know the rear door speakers do not go low enough for subwoofers.
Wiring in for the front doors.
My question is, has anyone seen anything in how low the rear doors will go ?
Wiring in my 6 channel lcq, and if the rear doors will go down to 80, 100 or 120 hz then I can leave it alone, if not then I will have to do things different.
Like wire the front doors and rear doors to the rear channel on lcq, then to a 4 channel amp for front and rear doors, and can adjust frequencies and front / rear levels on doors from amp, and splicing a line to the subwoofer also, so the front door speakers will go to line in for subwoofer and f/r door speakers.
